To operate the test bench for the Micron SDRAM VHDL model, follow the directions
given below:

1. Be sure all supporting files for the SDRAM are compiled into your library:
   
      util1164.vhd
      stdlogar.vhd
      io_utils.vhd
      mti_pkg.vhd

2. Next, compile the mt48lc64m4a2.vhd file and the test.vhd file.

3. Simulate the "tb" architecture. This is the testbench for the 256Mb SDRAM.
