我尝试使用Icarus编译带有其测试平台的mux.sv设计模块,但是出现以下错误vvp: array.cc:906: void compile_var2_array(char*, char*, int, int, int, int, bool): Assertion `0' failed.
Aborted (core dumped)
。
下面是测试平台的代码段
`include "mux.sv"
module tb_mux();
bit a0, a1, a2, d0, d1, d2, d3, d4, d5, d6, d7, out;
// read
bit expectedOutput;
int passedFile;
integer i;
bit [11:0] testvector[2047:0];
// design unit under test instantiation
mux dut(.out(out), .a0(a0), .a1(a1), .a2(a2), .d0(d0), .d1(d1), .d2(d2), .d3(d3), .d4(d4), .d5(d5), .d6(d6), .d7(d7));
initial begin
$readmemb("testcases", testvector);
passedFile = $fopen("passed.txt", "w");
if(passedFile)
$display("file opened");
else
$display("couldn't open the file");
end
task assertOutput;
begin
int unsigned cases = 0;
for (i = 0; i< 2048; i++)begin
{a0, a1, a2, d0, d1, d2, d3, d4, d5, d6, d7, expectedOutput} = testvector[i];
#10;
if(a0 == 1'b0 && a1 == 1'b0 && a2 == 1'b0 && out == expectedOutput)
cases = cases + 1;
else if(a0 == 1'b0 && a1 == 1'b0 && a2 == 1'b1 && out == expectedOutput)
cases = cases + 1;
else if(a0 == 1'b0 && a1 == 1'b1 && a2 == 1'b0 && out == expectedOutput)
cases = cases + 1;
else $display(0);
end
$fdisplay(passedFile, "%d", cases);
end
endtask
endmodule
我的测试台可能会发生什么错误,以产生此错误?
答案 0 :(得分:0)
我必须将位数据类型更改为逻辑,以使其可以与伊卡洛斯一起使用。
