Linux中使用Makefile来运行QuestaSim

本文主要是介绍Linux中使用Makefile来运行QuestaSim，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

环境：Win7x64，VMware15.0，centOS7.0，QuestaSim10.7c

假设已经编辑好了一个全加器还有运行这个DUT的testbech，代码如下：

点击查看代码 
// filename： full_adder.v

module full_adder(
  input wire a_in,
  input wire b_in,
  input wire c_in,
  output wire sum_out,
  output wire c_out
);

assign sum_out = a_in & b_in & c_in;
assign c_out = (a_in & b_in) | (b_in & c_in) | (a_in & c_in);

endmodule

和

点击查看代码 
// filename: full_adder_tb.v

module full_adder_tb; 
  reg ain, bin, cin;
  wire sumout, cout;
  
  //task 1: createan instance
  full_adder u_full_adder(
    .a_in (ain),
    .b_in (bin),
    .c_in (cin),
    .sum_out (sumout),
    .c_out (cout)
  );

  //task 2: clock and reset generator 
  parameter CLK_PERIOD = 20;
  reg clk, reset_n;

  initial begin
    clk = 0;
    forever begin
      #(CLK_PERIOD/2) clk = ~clk;
    end
  end
  
  initial begin
    reset_n = 0;
    #100 reset_n = 1;
  end

  //task 3: drive the stimulus and capture the response
  initial begin
    #110 ain = 0; bin = 0; cin =0; //00
    #20 ain = 0; bin = 1; cin =0; //01
    #20 ain = 1; bin = 0; cin =0; //01
    #20 ain = 1; bin = 1; cin =0; //10
    #20 ain = 0; bin = 0; cin =1; //01
    #20 ain = 0; bin = 1; cin =1; //10
    #20 ain = 1; bin = 0; cin =1; //10
    #20 ain = 1; bin = 1; cin =1; //11
    #50 $finish;
  end

  //task 4: check the result
  always @ (posedge clk) begin
    if(!reset_n)begin
      $display("%t:%m:resetting...",$time);
    end
    else begin
      $display("%t:%m:resetting finish!",$time);
    end 
  end

  initial begin
    #115 if({cout,sumout}!=2'b00)
      $display("%t, Error: {cout,sumout} = %b, ain = %b, bin = %b, cin = %b", $time, {cout,sumout}, ain, bin, cin);
    #20 if({cout,sumout} != 2'b01)
      $display("Error: {cout,sumout} = %b, ain = %b, bin = %b, cin = %b", {cout,sumout}, ain, bin, cin);
    #20 if({cout,sumout} != 2'b01)
      $display("Error: {cout,sumout} = %b, ain = %b, bin = %b, cin = %b", {cout,sumout}, ain, bin, cin);
    #20 if({cout,sumout} != 2'b10)
      $display("Error: {cout,sumout} = %b, ain = %b, bin = %b, cin = %b", {cout,sumout}, ain, bin, cin);
    #20 if({cout,sumout} != 2'b01)
      $display("Error: {cout,sumout} = %b, ain = %b, bin = %b, cin = %b", {cout,sumout}, ain, bin, cin);
    #20 if({cout,sumout} != 2'b10)
      $display("Error: {cout,sumout} = %b, ain = %b, bin = %b, cin = %b", {cout,sumout}, ain, bin, cin);
    #20 if({cout,sumout} != 2'b10)
      $display("Error: {cout,sumout} = %b, ain = %b, bin = %b, cin = %b", {cout,sumout}, ain, bin, cin);
    #20 if({cout,sumout} != 2'b11)
      $display("Error: {cout,sumout} = %b, ain = %b, bin = %b, cin = %b", {cout,sumout}, ain, bin, cin);
  end
  
  //task 5: dump wave form with the compile option -debug_all
  initial begin
    $vcdpluson;
  end

endmodule

方法一、运行QuestaSim界面来进行仿真

打开终端

输入：which vsim //查找QuestaSim位置并确认其可用性

输入：vsim 打开软件

balabala：

New Project: Name: full_adder, Default Library Name: work

-> Add existing file: full_adder.v, full_adder_tb.v

-> Compile All

-> Start simulation: work.full_adder_tb.v

-> Object: Add Wave -> Run or Run all

 

方法二：新建makefile，代码如下，终端输入make即可：

all: create_lib compile simulate 

create_lib:
	vlib work

compile:
	vlog -l comp.log -sv full_adder.v full_adder_tb.v

simulate:
	vsim -l sim.log -voptargs=+acc work.full_adder_tb -do "log -r *; run -all"
	
clean:
	rm -rf *work mti_lib transcript modelsim.ini *wlf seq.cr.mti seq.mpf *.log

 就可以啦。

 

两个小问题：

1、QuestaSim中代码模块字体显示过小的问题

2、novopt is not defined的问题

Good Luck !
