SpectreHDL is no longer supported since MMSIM61

coolono

仿真时出现“Spectrehdl is no longer supported since MMSIM61。Exiting AHDL compilation”
请问该怎么解决？

修改相应SpectreHDL文件为等效的Verilog-A文件，或者使用5141自带spectre。

通常这是电阻的AHDL模型出了问题，不过SpectreHDL和Verilog-A语法还算接近，所以修改还算容易。
例如module定义语法不同，前者是

1. module  (端口1，端口2，端口3……)(参数1，参数2，参数3，……)
   
2. {
   
3. ……
   
4. }
   

复制代码

后者是

1. module (端口1，端口2，端口3……);
   
2. ……
   
3. endmodule;
   

复制代码

例如热力学温度定义不同，
前者是$temp()，后者是$temperature。
例如节点语法不通，前者是node，后者是electrical。
例如analog语法不通，前者是

1. analog {……}
   

复制代码

后者是

1. analog begin……end
   

复制代码

在例如模拟赋值语法不同，前者是

1. V(p,n)  <-  Expression
   

复制代码

后者是

1. V(p,n)   <+   Expression
   

复制代码

另外建议Verilog-A的文件开头加上一句

1. `include "discipline.h"
   

复制代码

总的来说，举个例子，一个电阻的模型被修改成了Verilog-A格式如下：

1. `include "discipline.h"
   
2. 
   
3. module polyres_hdl (n2, n1, ctrl2, ctrl1); //(wr, lr, rtemp, jc1a, jc1b, jc2a, jc2b, tc1, tc2, etch, tnom, rsh0, rmaxvcoef, rminvcoef)
   
4. electrical     n2, n1, ctrl2, ctrl1;
   
5. 
   
6. parameter real lr=0.0;parameter real wr=0.0;
   
7. parameter real rtemp=($temperature - 273.15);
   
8. parameter real jc1a = 0;parameter real jc1b = 0;
   
9. parameter real jc2a = 0;parameter real jc2b= 0;
   
10. parameter real tc1 = 0;parameter real tc2 = 0;
    
11. parameter real etch = 0;parameter real tnom = 25.0;
    
12. parameter real rsh0 = 1;parameter real rmaxvcoef = 3;
    
13. parameter real rminvcoef = 0.33;
    
14. 
    
15. real dt, absv, vc1, vc2, tcoef, vcoef, r0, weff;
    
16. 
    
17.     analog begin   
    
18. dt = (rtemp - tnom);        
    
19. vc1 = jc1a + jc1b / lr;        vc2 = (jc2a + jc2b / lr) / lr;        
    
20. absv = abs(V(ctrl2, ctrl1));        
    
21. tcoef = 1.0 + dt * (tc1 + dt * tc2);        
    
22. vcoef = 1.0 + absv * (vc1 + absv * vc2);      
    
23.   vcoef = min(vcoef, rmaxvcoef);     
    
24.   vcoef = max(vcoef, rminvcoef);      
    
25. weff = (wr - 2.0 * etch);        
    
26. r0 = rsh0 * lr / weff * tcoef * vcoef;        
    
27. V(n2, n1) <+ I(n2, n1) * r0;   
    
28. end
    
29. endmodule
