15 years agoQuartus 9.1 PCIe pinout fiasco..
Anyone else get bit by this?
--------------------- Quartus II Mapping Issue with PCI Express (PCIe) Interfaces Using the Hard IP Block The Quartus II software versions 9.1, 9.1 SP1, and 9.1 SP2 incorrectly allow logical channel 0 to be placed in any physical channel for ×1 and ×4 PCIe Gen1 interfaces with the hard IP block. For correct operation with the hard IP block, logical channel 0 must be placed in physical channel 0. This issue is fixed in the Quartus II software version 10.0; however, Altera recommends upgrading to the Quartus II software version 10.0 SP1. If you have already designed or fabricated your boards using the incorrect mapping, file a service request using mysupport.altera.com for assistance to remedy this problem -------------------- My board is built and assembled already. I spent the last two weeks trying to figure out why my PCIe express core wouldn't work till I found this in the errata. When I compile it under 10.x it now errors out on the pins I chose for PCIe. Yes, I've logged this with Altera support. The response was effectively "I don't see a problem, your design compiles fine in Quartus 9.1".. Sigh... If anyone has received a coherent support response on this issue, please share it. I'm hoping I can use the soft PCIe core to work around this. Bet I have to pay for it.
