参考如下文章安装Synopsys EDA开发工具

Synopsys EDA工具的结构

下面使用Synopsys的EDA数字综合仿真工具直观感受以下数字设计的基本流程：

数字模块设计&仿真

counter_tb.v

`include "timescale.v"
module counter_tb;
  reg irst = 0;
  reg iclk = 0;
  wire [3:0] ocnt;
  initial begin
    irst = 1; #100;
    irst = 0; #300;
    $stop;
    #1000;
    $finish;
  end
  always begin #5 iclk = !iclk; end
  counter counter_test(
    .irst(irst),
    .iclk(iclk),
    .ocnt(ocnt)
  );
  initial
  $monitor("At time %t, ocnt = %d", $time, ocnt);
  initial
  begin
    //$dumpfile("counter_test.vcd");  //$dumpvars(0, counter_test);
    $fsdbDumpfile("counter_tb.fsdb"); //testbench的名字       
    $fsdbDumpvars();
    $fsdbDumpSVA();
    $fsdbDumpMDA();
  end
endmodule

timescale.v

`timescale 1ns/1ps

counter.v

`include "timescale.v"
module counter(irst, iclk, ocnt );
  input irst, iclk;
  output reg [3:0] ocnt;
  always @ (posedge iclk)
    if(irst)
      ocnt <= 4'b0000;
    else
      ocnt <= ocnt + 1'b1;
endmodule

Makefile

all:
	iverilog -o counter_test $(notdir $(wildcard ./*.v))
	vvp -n counter_test -lxt2
	cp counter_test.vcd counter_test.lxt

sim:
	gtkwave counter_test.lxt

vcs:
	vcs -R -full64 -timescale=1ns/1ns -fsdb -f file.l

verdi:
	verdi -f file.l -ssf counter_tb.fsdb

clean:
	rm -fr *.lxt *.vcd
	rm -fr counter_test

file.l 是verilog源码清单文件：

counter_tb.v
counter.v
timescale.v

VCS编译&综合，执行make vcs：

vcs -R -full64 -timescale=1ns/1ns -fsdb -f file.l

verdi查看波形，q退出ucli%,执行make verdi,实际上是执行如下命令查看波形： 

verdi -f file.l -ssf counter_tb.fsdb

波形和GTKWAVE得到的波形是一样的：
