pcie gen3x8 DMA EndPoint with HPTXS path is not meeting timing - pcie gen3x8 DMA EndPoint with HPTXS path is not meeting timing Hi , I have generated an FPGA model with PCIe DMA EP and onchip Memory as shown in the attached "DMA_EP_OnchipMem_model.png" file. I have instantiated an Onchip Memory of size 16MB. Seeing Setup violations due to large Routing delay's as shown in the "Setup_viol_Data_Path.png" What is the ideal method to fix these Setup violations?

Or you can add pipeline stages.

Just to let you know that Intel has received your support request and I am assigned to work on it. Allow me some time to look into your issue. I shall come back to you with findings. Thank you for your patience. Best regards, Wincent_C_Intel Replies: Re: pcie gen3x8 DMA EndPoint with HPTXS path is not meeting timing I realized that the longer IC (Inter Connection) delays are due to the paths to farther Block RAMS blocks. When I reduced OnChip memory size from 16MB to 2MB , The design met Setup time. Is there a way close timing without reducing the Block RAM usage? Regards Siva Kona
