Q: Does Verific replace constant expressions with their respective values?
I have in my Verilog code:
parameter size = 8; reg [size-1:0] foo;
I expect the range of "foo" to be [7:0]. How do I get the range [7:0]?
If run-time flag "veri_replace_const_exprs" is set, Verific will replace constant expressions with their respective values in static elaboration.
In C++:
RuntimeFlags::SetVar(" veri_replace_const_exprs", 1) ;
In Tcl:
set_runtime_flag "veri_replace_const_exprs" 1
