Can HSPICE accept parameter as string which used in .so file?

[Hyunseok]

Hi Guys,

I'm trying to use HSPICE circuit file using external library(.so file).
I can't find what is the problemes in below process.

1. .so file
In this external library, I want to input 'string'. So Here is sample C source code.

#include <stdio.h>
#include <string.h>

static double char_match(char *c1)
{
     if (strcmp(c1,'test_string'))
     {
         return 0;
     }
    else
    {
        return 100;
    }

2. .sp file
With this circuit description, string can't be imported to "char_match" function

*
.option CFLflag
.cfllib './sample_cfl2.so'
.cfl_prototype char_match(param)

.param p1=str('test_string')
.param p2=char_match(p1)
...

And Here is the debug message

**warning** (sample_cfl2.sp:xx) Parameter XXX is ignored
 Using CFL library ./sample_cfl2.so

  **error** (sample_cfl2.sp:9) Illegal character in statement in column   xx : char_match(p1)
  **error** (sample_cfl2.sp:9) Illegal character in statement in column   xx : char_match(p1)

Can anyone help?
