I have a program that, in post-translate simulation (XST synthesis, ISE simulation, 10.1i) locks up in loading one of the input streams, but works OK in behavioral pre-synthesis simulation of the Impulse C HDL output. Any ideas? Attached is the screen shot from ISE, notice Memory collision errors reported at ~ 100 ns, and input stream hostcontrol locks up at ~ 200 ns. When working properly, as it does in pre-synthesis simulation, many more data points will be loaded into hostcontrol - it won't lock out hostcontrol_rdy.

Thank you.

Hi,
Your description and emailed screenshot are not enough to troubleshoot the issue. Please send your complete Impulse C project (.c,.h, .icProj) as well as HDL testbench files being used for review.

Best Regards,
