Honored ContributorHi Hua,
--- Quote Start --- We are indeed using QII 12.1sp1, and the first line of the generated vhd file also indicates it was generated from 12.1: -- megafunction wizard: %IP Compiler for PCI Express v12.1% I also double checked the MegaWizard configurations page by page against the copy that worked (and compiled in 11.0), they are the same. --- Quote End --- Using a file-difference program would be easier :) Did you check the ALTGX_RECONFIG component? Have you read through the document I wrote and posted with this thread: http://www.alteraforum.com/forum/showthread.php?t=35678 I haven't tried these designs with 12.1sp1, but I know they worked with the tools I used when I wrote the document. You could download the code and check it out. --- Quote Start --- Basically we supplied the same source files and configuration files as far as I can tell, to two different compilation processes (11.0 vs 12.1sp1), both compiled successfully but one image fails to be detected by BIOS. Is there anything in the hard core that I can use signaltap to check if the it is in working condition? Like checking the link status or something like that? --- Quote End --- Check the configuration controller completes its reset sequence. The PDF in the thread linked to above has some SignalTap II traces you can try to re-produce. Cheers, Dave
