Occasional ContributorTiming error on Arria 10 PCIe core design
I have an Arria 10 design with a PCIe core (hard-IP, 8 lanes, gen 3, Avalon memory-mapped, w/ DMA). The only timing errors I am getting are related to the reset generated by the PCIe core. The rese...

Frequent ContributorHi Sir,
I compile PCIe example design in Arria10 using 18.1. The worst recovery slack that i get it 0.792. I think it is impossible the palce and routing cause the violation change from 792ps to -700ps.
What is the device speed grade (or OPN) that you use for your compilation?
Suggestion, can you duplicate a copy of your design to other directory. Remove other logic component as much as possible and remain PCIe IP, compile and see if you still get the same timing results.
