simulate PCIe in Pipe mode - simulate PCIe in Pipe mode Dear Intel Support/Expert, I have some problems while simulate AN829 in PIPE mode. I am using Quartus 21.3, PCIe Gen3 8 line. I can run in serial mode, but failed to run in PIPE mode. 1. question. I noticed that at this link Design Example - PHY Interface for PCI Express (PIPE) - Intel Communities it claimed that the PIPE only supports Gen1 and Gen2. is this true in the latest Quartus 21.3. if true, then ignore this post. if not please have a look at the attached file. it has detail description of the problem I have. thank you, David Replies: Re: simulate PCIe in Pipe mode Hi As your question been addressed.
