hello everyone 
I have question on verdi compiler.
Usually we use parameters with pre-processor keyword `define
I defined on tb_top.v like this,
`define TARGET_FPGA
`ifdef TARGET_FPGA
`define SBIT 8
`else
`define SBIT 6
and I used parameter on tb_sub.v that defined on tb_top like this,
module tb_sub (
input [`SBIT:0] A,
input [`SBIT:0] B,
output [`SBIT:0] O
);
In this case, vcs or ncsim compiler dose not make trouble to interpret the pre-processor
BUT, verdi compiler make a noise.
*Error* failed to find identifier SBIT
how can I avoid this message??
Best Regards,
Billy
