Passing arguments from irun command line to top module

You can use -defparam. -DEFparam parameter_pathname=value, eg. -defparam top.dut.u1.param4=8 .... Best regards, Mickey

How would you pass an enum to the defparam? I get weird numbers in the parameter.

Thanks in advance,

Is this what you're referring to:

typedef enum bit {NO, YES} bool_t;

module test;
dut dut ();
defparam dut.p = NO;
endmodule

module dut ();
parameter bool_t p = YES;

initial $display ("p is %n", p);
endmodule

Uhm, interesting enough the example you are using is working correctly (tried on edaplayground.com), but this one does not work correctly:

typedef enum bit {NO, YES} bool_t;

module test;
dut dut ();
endmodule

module dut ();
parameter bool_t p = YES;

initial $display ("p is %n", p);
endmodule

the -defparam options passed to incisive does not overwrite the locally defined parameter. Moreover I have the following situation www.edaplayground.com/.../ufn where the outcoming output of the parameter value is completely wrong.

What is the main difference between these examples?

Thanks for your support,

Al

It looks like ENUMs are not getting taken from command line. If I pass the numerical equivalence (NO=0, YES=1), then it works as expected:

irun test.sv -defparam test.dut.p=0

p is NO
