error when passing a string to ncutils

JMGGL

This is what I am trying to do:

parameter [1023:0] chip_name="tb_top.I_0.";

wire [1023:0] path_name;

assign  path_name    = {chip_name,"module1.module2.signal"};

$nc_mirror("signal",path_name","verbose");

 

*And the following message error appears:

Non-string argument specified for $nc_mirror task...

 

I tried to pass directly  path_name, without concatenation, and same problem. Also with other ncutils: nc_force, nc_release... Does anybody know how to do it?

Thanks in advance.

  • Thanks Tim, but still with same issue: Non-string argument specified for $nc_mirror task...

    You were right when you said that the path was empty, so I fixed it.

    Now I mixed your solutions:

    parameter [1023:0] chip_name="tb_top.I_0.";

    reg [1023:0] path_name;

    initial  path_name    = {"\"",chip_name,"module1.module2.signal","\""};

    $nc_mirror("signal",path_name,"verbose");

     

    With initial $display("signal %0s",path_name),  the path seems to be correct:

    "tb_top.I_0.module1.module2.signal"

     

    Any other idea?
