ASIC/FPGA Design and Verification Out Source Services

A simple c-code program to read a memory array from verilog RTL, using VPI.

1. The former page discussed the simple verilog file, which served as the example's DUT. Then I explained the c code. This page presents the script, which used to compile and run this simple test.


2. The script is generic and it assumes that both verilog and c code use the very same name. If any step in the script compilation (c, verilog, simulation) fails, the script stops.


3. I used the free verilog simulator, icarus. It has a special command to compile the c-code vpi, iverilog-vpi, which makes life easier:
   clear;./cmp.unx itr | tee 1.txt
   
   #!/bin/bash
   
   rm $1.vvp *.vcd
   iverilog-vpi $1.c || exit
   iverilog -o$1.vvp $1.v || exit
   vvp -M. -m$1 $1.vvp || exit
