SV %p support for class objects

[svenka3]

Hello, I see vvl throwing error for %p - a handy format for class object printing in SV (See below for sample error). I have pasted a code as well below.

Is this easy to add in Icarus?

Thanks Srini

iverilog -g2012 a.sv [Srinivasans-MacBook-Air-2:src/WIP/run_dir] srini% vvp a.out ERROR: a.sv:17: $display does not support argument type (vpiClassVar). ERROR: a.sv:17: $display does not support argument type (vpiClassVar).

Code:

program p; class a; int a1; endclass : a

class b extends a; int abcd; endclass : b

a a0; b b0;

initial begin : test a0 = new(); b0 = new(); $display ("a0: %d b0: %d", a0.a1, b0.abcd); $display ("a0: %p b0: %p", a0, b0); end : test

endprogram : p

No, I don't think this is easy. VPI access to class variables does not appear to be implemented in vvp. Also, the compiler converts packed structs to vectors, so vvp has no knowledge of the struct members.
