I modified the SPI OVM testbench that can be downloaded from Mentor's web site. The testbench is customized to test our design. I have been using Mentor's Questa tool to run simulation while we evaluate the tool. The testbench has worked with Questa. We are also evaluating Cadence's Incisive. I started to compile and run simulation with Incisive. It apprears to compile OK but $cast does not seem to work right.
seq_item_port.get_next_item(req); $cast(cloned_item, req.clone()); ap.write(cloned_item);
This works fine with Questa but not with Incisive. The data members in req are defined but not cloned_item after $cast.
Is there any reason that this does not work with Incisive? Questa was sourceing OVM-2.1.2 source code.
