Bluespec $display within function

Bluespec complains when I try to use $display within a function definition.

It is only allowed within a rule definition.

Is there a way that I can get to display variable names within a function?

I think it might be using the ActionValue# but I cannot get the syntax right. I also cannot find examples online.

Thanks

Solution

  • One correct syntax is -

    function ActionValue#(rtype) func(...)
= actionvalue
    do something;
    $display(...);
    return val;
endactionvalue;
