-Usage

-PCK_FIO is a VHDL package that defines  fprint, a function -for formatted file output. -

After installing the package you can call fprint as follows: -

  fprint(F, L, Format, fo(Expr_1), fo(Expr_2), ... fo(Expr_n));
-where F is the filehandle and L is the line variable. -

The argument Format is the format string, which consists of ``normal'' -substrings which are copied verbatim, and format specifiers, starting with -'%'. -A typical format string looks as follows: -

   "Arg1 = %6r, Arg2 = %10d, Arg3 = %-5r\n"
-The remaining arguments are the expressions whose results you want to write -to the file, embedded in fo function calls. There can be 0 to -32 of such arguments. The expressions can be of any type for which an fo -function exists. String expressions can also be called directly. -

-

-

-The file output function 'fo'

-The fo (file output) functions do the trick. They -return a tagged string representation that is meaningful to format specifiers. -Here are some examples: -
  fo (signed'("1100"))   returns "S:1100" 
-  fo (unsigned'("1100")) returns "U:1100" 
-  fo (TRUE)              returns "L:T"
-  fo (127)               returns "I:127"
-The internal behavior of fo is irrelevant to the typical user. -

The fo function is currently overloaded as follows: -

  function fo (Arg: unsigned)          return string;
-  function fo (Arg: signed)            return string;
-  function fo (Arg: std_logic_vector)  return string;
-  function fo (Arg: std_ulogic_vector) return string;
-  function fo (Arg: bit_vector)        return string;
-  function fo (Arg: integer)           return string;
-  function fo (Arg: std_ulogic)        return string;
-  function fo (Arg: bit)               return string;
-  function fo (Arg: boolean)           return string; 
-  function fo (Arg: character)         return string;
-  function fo (Arg: string)            return string;
-  function fo (Arg: time)              return string;
- -
-
- -

-Format specifiers

-The general format of a format specifier is: -
   %[-][n]c
-The optional - sign specifies left justified output; default is -right justified. -

The optional number n specifies a field-width. If it is not specified, -fprint -does something reasonable. -

c is the conversion specifier. Currently the following conversion -specifiers are supported: -

-
-r
- -
-reasonable output format (inspired by Synopsys VSS)
- -
Prints the ``most reasonable'' representation e.g. hex for -unsigned, signed and other bit-like vectors (not preferred for integers)
- -
-b
- -
-bit-oriented output
- -
-d
- -
-decimal output
- -
-s
- -
-string output (e.g. in combination with 'IMAGE for enum types)
- -
-q
- -
-``qualified'' string output (shows internal representation from fo)
- -
-{}
- -
-Iteration operator, used as follows:
- -
-%n{<format-string>}
- -
In this case, n is the iteration count and is mandatory. Iteration -can be nested.
- -
-

-Special characters

-To print a double-quote,  use '""' in the format string (VHDL -convention). To print the special characters, '\', and '%', -escape them with '\'. To prevent '{' and '}' -from being interpreted as opening and closing brackets in iteration strings, -escape them with '\'. -

A newline is specified in the format string by '\n'. -

-

-

-Things to notice

-The fprint function expands into VHDL write and writeline -commands. As in plain VHDL, nothing will be written to the output file -until a writeline is given. Therefore, don't forget to include -'\n' -commands in the format string, or it ``will not work''. -

The preferred format specifier for integers is, naturally, %d. -This calls the VHDL write for integers. If you specify a field -width that is too small, the field will automatically be expanded. If you -use %r for integers, the field is not expanded automatically, which -means that some digits are simply thrown away. This may sometimes be useful -but it is also dangerous. Look at the test bench output for differences -between %d and %r output. -

When using the %d format specifier, the VHDL constraints for -the allowed integer range apply. -

In VHDL, signed/unsigned types have been standardized only relatively -recently, in the package IEEE.numeric_std. The lack of a standard -has caused (and is causing) portability issues. The most popular non-standard -package that defines signed/unsigned is IEEE.std_logic_arith from -Synopsys. PCK_FIO has been developed with this latter package, and still -refers to this package by default. However, PCK_FIO  works with -IEEE.numeric_std -as well. To use IEEE.numeric_std, replace the reference to IEEE.std_logic_arith -in the source code.  This needs to be done consistently in a design -database (e.g. in the PCK_FIO test bench as well). -

-

-

-Methodology notes

-The obvious application for fprint is in test benches, to produce -output files that trace the simulation behavior. -

Another interesting application for fprint is to produce info, -warning and error messages in your models. As it can take arguments, fprint -is much better suited for this task than VHDL's assert or report -statements. Actually fprint produces its own (few) warning messages. -

An advanced usage is the generation of test vectors in a specific format. -Instead of using the fo functions, you can write your own set -of functions that return the symbols of a specific test format in a way -that is understandable to the fprint format specifiers. As an -example, when a high output value should be represented using the symbol -'H' it suffices to write a conversion function that returns "B:H" and call -it in combination with the %b format specifier. -

-

-

-Parametrization

-Prefix and postfix strings for bit-oriented and hex-oriented output are -parameterizable in the packages to accommodate different output styles. -The settings in the distribution are such that hex output is indicated -by the prefix '0x', while  bit output prefix and postfix are empty -strings. -

You can adapt the output style by modifying the following constants -in the package header: -

   -- prefix string for hex output -
  -- VHDL style:    "X""" -
  -- Verilog style: "h'" -
  -- C style:       "0x" -
  constant FIO_h_PRE:  string := "0x"; -

  -- postfix string for hex output -
  -- VHDL style:    """" -
  constant FIO_h_POST: string := ""; -

  -- prefix string for bit vector output -
  -- VHDL style:    "B""" -
  -- Verilog style: "b'" -
  constant FIO_bv_PRE:  string := ""; -

  -- postfix string for bit vector output -
  -- VHDL style:    """" -
  constant FIO_bv_POST: string := ""; -

  -- prefix string for bit output -
  -- VHDL style:    "'" -
  -- Verilog style: "b'" -
  constant FIO_b_PRE:  string := ""; -

  -- postfix string for bit output -
  -- VHDL style:    "'" -
  constant FIO_b_POST: string := ""; -

-

-

-Test bench

-Included in the distribution is a file TB_PCK_FIO.vhd with a test -bench for the PCK_FIO package. The file PCK_FIO.out.gold contains -the expected output. If you run the test bench it should produce the file -PCK_FIO.out -that should be identical to PCK_FIO.out.gold. The source files -should be analyzed in a VHDL library EASICS_PACKAGES. -

A good way to understand fprint is to inspect the test bench -and what it produces. -

-

-

-Known limitations and problems

-This VHDL package is an implementation of a flexible concept. It is likely -to be extended and modified in the future. Backward compatibility is not -guaranteed. Therefore, it is not recommended to give this package the status -of a company-wide standard package (or even worse, a VHDL standard package). -Rather, it should be linked with a particular project (and it can be regarded -as a standard package within that project). -

PCK_FIO is written in standard VHDL Std1076-1987. Nevertheless, some -simulators/versions have problems with the package. The following is an -overview of currently known issues: -

-Usage

-PCK_FIO is a VHDL package that defines  fprint, a function -for formatted file output. -

After installing the package you can call fprint as follows: -

  fprint(F, L, Format, fo(Expr_1), fo(Expr_2), ... fo(Expr_n));
-where F is the filehandle and L is the line variable. -

The argument Format is the format string, which consists of ``normal'' -substrings which are copied verbatim, and format specifiers, starting with -'%'. -A typical format string looks as follows: -

   "Arg1 = %6r, Arg2 = %10d, Arg3 = %-5r\n"
-The remaining arguments are the expressions whose results you want to write -to the file, embedded in fo function calls. There can be 0 to -32 of such arguments. The expressions can be of any type for which an fo -function exists. String expressions can also be called directly. -

-

-

-The file output function 'fo'

-The fo (file output) functions do the trick. They -return a tagged string representation that is meaningful to format specifiers. -Here are some examples: -
  fo (signed'("1100"))   returns "S:1100" 
-  fo (unsigned'("1100")) returns "U:1100" 
-  fo (TRUE)              returns "L:T"
-  fo (127)               returns "I:127"
-The internal behavior of fo is irrelevant to the typical user. -
  -
The fo function is currently overloaded as follows:
- -
  function fo (Arg: unsigned)          return string;
-  function fo (Arg: signed)            return string;
-  function fo (Arg: std_logic_vector)  return string;
-  function fo (Arg: std_ulogic_vector) return string;
-  function fo (Arg: bit_vector)        return string;
-  function fo (Arg: integer)           return string;
-  function fo (Arg: std_ulogic)        return string;
-  function fo (Arg: bit)               return string;
-  function fo (Arg: boolean)           return string; 
-  function fo (Arg: character)         return string;
-  function fo (Arg: string)            return string;
-  function fo (Arg: time)              return string;
- -


To support null-terminated strings, the function fo(Arg: -string) processes Arg up to the first NUL character, -if any. If you want the whole string to be outputted you can just enter -the string as a direct argument in fprint.  See also the -examples in the testbench. -

-
- -

-Format specifiers

-The general format of a format specifier is: -
   %[-][n]c
-The optional - sign specifies left justified output; default is -right justified. -

The optional number n specifies a field-width. If it is not specified, -fprint -does something reasonable. -

c is the conversion specifier. Currently the following conversion -specifiers are supported: -

-
-r
- -
-reasonable output format (inspired by Synopsys VSS)
- -
Prints the ``most reasonable'' representation e.g. hex for -unsigned, signed and other bit-like vectors (not preferred for integers)
- -
-b
- -
-bit-oriented output
- -
-d
- -
-decimal output
- -
-s
- -
-string output (e.g. in combination with 'IMAGE for enum types)
- -
-q
- -
-``qualified'' string output (shows internal representation from fo)
- -
-{}
- -
-Iteration operator, used as follows:
- -
-%n{<format-string>}
- -
In this case, n is the iteration count and is mandatory. Iteration -can be nested.
- -
-

-Special characters

-To print a double quote,  use '""' in the format string (VHDL -convention). To print the special characters, '\', and '%', -escape them with '\'. To prevent '{' and '}' -from being interpreted as opening and closing brackets in iteration strings, -escape them with '\'. -

A newline is specified in the format string by '\n'. -

-

-

-Things to notice

-The fprint function expands into VHDL write and writeline -commands. As in plain VHDL, nothing will be written to the output file -until a writeline is given. Therefore, don't forget to include -'\n' -commands in the format string, or it ``will not work''. -

The preferred format specifier for integers is, naturally, %d. -This calls the VHDL write for integers. If you specify a field -width that is too small, the field will automatically be expanded. If you -use %r for integers, the field is not expanded automatically, which -means that some digits are simply thrown away. This may sometimes be useful -but it is also dangerous. Look at the test bench output for differences -between %d and %r output. -

When using the %d format specifier, the VHDL constraints for -the allowed integer range apply. -

In VHDL, signed/unsigned types have been standardized only relatively -recently, in the package IEEE.numeric_std. The lack of a standard -has caused (and is causing) portability issues. The most popular non-standard -package that defines signed/unsigned is IEEE.std_logic_arith from -Synopsys. PCK_FIO works with both packages,  but refers to the standard -package IEEE.numeric_std by default. To use IEEE.std_logic_arith -instead, replace the reference to IEEE.numeric_std in the source -code.  This needs to be done consistently in a design database (e.g. -in the PCK_FIO test bench as well). -

-

-

-Methodology notes

-The obvious application for fprint is in test benches, to produce -output files that trace the simulation behavior. -

Another interesting application for fprint is to produce info, -warning and error messages in your models. As it can take arguments, fprint -is much better suited for this task than VHDL's assert or report -statements. Actually fprint produces its own (few) warning messages. -

An advanced usage is the generation of test vectors in a specific format. -Instead of using the fo functions, you can write your own set -of functions that return the symbols of a specific test format in a way -that is understandable to the fprint format specifiers. As an -example, when a high output value should be represented using the symbol -'H' it suffices to write a conversion function that returns "B:H" and call -it in combination with the %b format specifier. -

-

-

-Parametrization

-Prefix and postfix strings for bit-oriented and hex-oriented output are -parameterizable in the packages to accommodate different output styles. -The settings in the distribution are such that hex output is indicated -by the prefix '0x', while  bit output prefix and postfix are empty -strings. -

You can adapt the output style by modifying the following constants -in the package header: -

   -- prefix string for hex output -
  -- VHDL style:    "X""" -
  -- Verilog style: "h'" -
  -- C style:       "0x" -
  constant FIO_h_PRE:  string := "0x"; -

  -- postfix string for hex output -
  -- VHDL style:    """" -
  constant FIO_h_POST: string := ""; -

  -- prefix string for bit vector output -
  -- VHDL style:    "B""" -
  -- Verilog style: "b'" -
  constant FIO_bv_PRE:  string := ""; -

  -- postfix string for bit vector output -
  -- VHDL style:    """" -
  constant FIO_bv_POST: string := ""; -

  -- prefix string for bit output -
  -- VHDL style:    "'" -
  -- Verilog style: "b'" -
  constant FIO_b_PRE:  string := ""; -

  -- postfix string for bit output -
  -- VHDL style:    "'" -
  constant FIO_b_POST: string := ""; -

-

-

-Test bench

-Included in the distribution are the files TB_PCK_FIO_1987.vhd and -TB_PCK_FIO_1993 with a test bench,depending on the standard you're -running, for the PCK_FIO package. The file PCK_FIO.out.gold contains -the expected output. If you run the test bench it should produce the file -PCK_FIO.out -that should be identical to PCK_FIO.out.gold. The source files -should be analyzed in a VHDL library EASICS_PACKAGES. -

A good way to understand fprint is to inspect the test bench -and what it produces. -

-

-

-Known limitations and problems

-This VHDL package is an implementation of a flexible concept. It is likely -to be extended and modified in the future. Backward compatibility is not -guaranteed. Therefore, it is not recommended to give this package the status -of a company wide standard package (or even worse, a VHDL standard package). -Rather, it should be linked with a particular project (and it can be regarded -as a standard package within that project). -

PCK_FIO is available in either standard VHDL Std1076-1987 or standard -VHDL Std1076-1993. Nevertheless, some simulators/versions have problems -with the package. The following is an overview of currently known issues: -

Arithmetic operations involving UFix, SFix and other - -- numeric types. - -- The operators are overloaded for most of the sensible - -- combinations of SFix, UFix, UNSIGNED, SIGNED and INTEGER. - -- - -- IMPORTANT NOTE: - -- Arithmetic operators return a result that is wide enough - -- and precise enough so that no information is lost. THIS IS - -- SIGNIFICANTLY DIFFERENT FROM THE BEHAVIOUR OF numeric_std. - -- In the detailed description that follow, "scaling" means - -- the numerical value (weight) of the least significant bit - -- in a fixed-point value. - -- - -- ADDITION returns a result whose least significant bit - -- is the same as the least significant bit in either operand, - -- and whose most significant bit is one position higher than - -- the most significant bit in either operand. Addition of - -- two operands having the same bounds therefore results in - -- a growth of one bit at the most significant end. - -- - -- SUBTRACTION where one or both operands are signed behaves - -- in the same way as addition. Subtraction where both operands - -- are unsigned returns a result whose most significant bit - -- position is the same as the most significant bit in either - -- operand, and whose least significant bit is the same as the - -- least significant bit in either operand. - -- - -- MULTIPLICATION returns a result whose width is the sum of - -- the widths of its two operands, and whose scaling is the - -- product of its two operands' scalings. - -- - -- UNARY NEGATION always gives a result having one more - -- significant bit than the operand. - -- - -- ABSOLUTE VALUE always gives a result having exactly the - -- same subtype as its operand. - -- - -- In binary operations where one operand is a fixed-point type - -- and the other is an integer numeric type, the integer operand - -- is first converted to a fixed-point type of the same subtype - -- as the other operand using Copy_V with default rounding and - -- overflow modes. The operation is then performed between two - -- fixed-point operands in the normal way. - -- - ------------------------------------------------------------------ - - - ------------------------------------ - -- A.1.

THIS IS - -- SIGNIFICANTLY DIFFERENT FROM THE BEHAVIOUR OF numeric_std. - -- In the detailed description that follow, "scaling" means - -- the numerical value (weight) of the least significant bit - -- in a fixed-point value. - -- - -- ADDITION returns a result whose least significant bit - -- is the same as the least significant bit in either operand, - -- and whose most significant bit is one position higher than - -- the most significant bit in either operand. Addition of - -- two operands having the same bounds therefore results in - -- a growth of one bit at the most significant end. Addition - -- of an integer to a UFix or SFix is accomplished by first - -- converting the integer to the same subtype as the other - -- operand, thereby giving rise to one-bit growth; default - -- truncation and rounding modes are used for the conversion. - -- - -- SUBTRACTION where one or both operands are signed behaves - -- in the same way as addition. Subtraction where both operands - -- are unsigned returns a result whose most significant bit - -- position is the same as the most significant bit in either - -- operand, and whose least significant bit is the same as the - -- least significant bit in either operand. - -- - -- MULTIPLICATION returns a result whose width is the sum of - -- the widths of its two operands, and whose scaling is the - -- product of its two operands' scalings. - -- - -- UNARY NEGATION always gives a result having one more - -- significant bit than the operand. - -- - -- ABSOLUTE VALUE always gives a result having exactly the - -- same subtype as its operand. - -- - -- In binary operations where one operand is a fixed-point type - -- and the other is an integer numeric type, the integer operand - -- is first converted to a fixed-point type of the same subtype - -- as the other operand using Copy_V with default rounding and - -- overflow modes.
