Why does the Arria 10 nPOR input not keep the PCIe IP in reset?

Description

When using Quartus® Prime software versions 16.0 and later, the Arria® 10 PCI Express® Hard IP npor signal does not reset the HIP when driving a 0 or 1.

Resolution

As a work around in v16.0 the RTL can be modified to enable a user side reset, by making the change below.

Change the USE_ALTPCIE_RS_HIP_LOGIC =1 , module "<variant>_altera_pcie_a10_hip_<letters>.v

This problem will be fixed in a future release of the Quartus software.
