Access custom VHDL types in TCL script

Hi Guys,

I'm having a custom type in VHDL:

type alu_op_code is ( ALU_OP_IDLE, ... );

Now having a testbench written in TCL i wawnt to force signals of type alu_op_code.

How to actually do that? For std_logic data this is possible usng:

force signal_name '0'

But how to use that with custom types?

Thank you in advance! Cheers Robert

I think this is why my testbenches tend to be in VHDL.

If all else fails you can add a tedious but trivial VHDL wrapper to interface between everything-is-an-integer land and a decent type system.

Thank you for your response. This is what I did meanwhile. It works but I thought if there other possibilities.

Not sure what simulator you use but if you use Modelsim you can force enumerated types.

signal opc : alu_op_code;

force -freeze /bla/opc ALU_OP_IDLE 0

Good luck, Hans
