下面是 C 中用于模糊输入的代码。 我试图将其转换为 verilog 语法, 但我在数据类型和数据类型上有很多问题。 错误会继续堆积 。

float fuzzify_MF(float x,a,b,c,d) //x=crisp input 
{ 
float dom; 
if ( x >a && x <b) 
{ dom=(x-a)/(b – a); } 
else if (x>c && x<d) 
{ dom=(d-x)/(d-c); } 
else if (x>=b && x<=c) 
{dom=1.0; } 
else 
{ dom=0; } 
return dom; 
} 
问题回答

why dont you try using PLI. Try this link : PLI tutorial

您可以使用 PLI 解决这个问题, 但是如果你想看起来很酷, 并且仍然能解决这个问题, 请使用 系统 Verilog 的 DPI 。

http://www.project-veripage.com/dpi_tutiment_1.php

您可以在 Verilog 中通过使用 PLI 导入“ C” 函数。

包含以下带有 C 函数的标题文件 :

#include <svdip.h>

现在在 Verilog 模块中 :

module top;
  import "DPI-C" context function shortreal fuzzify_MF(shortreal x, shortreal a, shortreal b, shortreal c, shortreal d);
  shortreal t;

  initial
  begin
    t = fuzzify_MF(<Arguments>);
  end    
endmodule
