Hi, I read a paper on FPGA design. It has the following statements:
"Successfully simulated programs might not work on device because synthesizer tries to optimize design and it can delete some connections which affect result. Hence a good knowledge of synthesizer is of importance in FPGA program development."
I have done some small and medium FPGA projects, but never experience surprising synthesis result as the above statement. Could you give me an example to show the XST synthesis control to turn a failure to success?
Thanks,
