a5,hard ip of pcie,how connect perstn？

Question

the perstn from pc mother board`s pcie slot is not connect to the dedicated io pin of arria5, when fit, error report.how can i fix it?

altera_forum · Answer

The perstn from motherboard needs connect to pin_perst of pcie core.

If the Arria V FPGA has 2 PCIe cores, each PCIe core instance has its own pin_perst signal. You

must connect the pin_perst of each Hard IP instance to the

corresponding nPERST pin of the device. These pins have the

following locations:

- NPERSTL0: bottom left Hard IP block

- NPERSTR0: bottom right Hard IP block
