Dear Sir,
I have questions about Spartan 3A FPGA post simulation.
Can I believe the result of FPGA postsim?
I check the postsim waveform and find a cell (XBUF) inserted by PAR tool between output PAD and the latest FF. This XBUF is not expected.
And cell delay is so large.
How should I do to delete this XBUF?
Thank you very much.
