seeing is beliving :)
the modelsim precompiled version was offered by HT-LAB for free for some time, but that did not trigger my curiosity level - but now as also EDIF version are available its really simple and easy to test drive the CPU86 ipcore in FPGA! it took about 1 hour to get the core todo something in an Virtex4, the utilization in FX12 was 51% of the slices.
there is ChipScope Pro snapshot of the first succesfull test.
and the CPU86 is from HT-LAB
Hans are you here?
