To operate the test bench for the Micron SDRAM VHDL model, follow the directionsgiven below:1. Be sure all supporting files for the SDRAM are compiled into your library:         util1164.vhd      stdlogar.vhd      io_utils.vhd      mti_pkg.vhd2. Next, compile the mt48lc1m16a1.vhd file and the test.vhd file.3. Simulate the "tb" architecture. This is the testbench for the SDRAM.
