Benchtest dependign on configuration

[Olaf Petzold]

Hello,

is there a way to find out inside the bench test which configuration is
used/mapped for the dut?
E.g. a feature is generated by generic and I want to use the same TB for
both (feature on/off).

Thanks
Olaf

I would have the testbench drive
the DUT generic map with
whatever generic value is appropriate.

Thanks Mike,

you mean to instance two duts, configured by generic map each? No use of
configurations to swap between both?

Thanks

I would either test
two direct instances in one sim

vsim test_foo;

or script multiple sims with appropriate
generic constants driven from the command line.

vsim -Gsome_feature=true test_foo;
vsim -Gsome_feature=false test_foo;
