Using Quartus 19.1 and Platform Designer on Windows I get an error when executing Generate on a Cycleone IV GX where I have instantiated a PCIe interface using PCIe hard IP. This works in QSys on Quartus 16. Is there a work-around or am I stuck using 16?

Hi David,

I installed the quartus lite 19.1 in my PC and I also get the same errors when generating the Qsys. Looks like this is a valid issue.

I reported this to the development team.

However, from your side, I will suggest you just stick on the older version. The reason is because for Lite edition, Intel planning to obsolete it in the future, thus it is unlikely we will put any fix for this. After get the confirmation, mostly it will just go with an errata/known issue.

Also, for Cyclone IV, I don't see is there any enhancement implement in recent quartus version. So, using the older version or newer version will give the same results. My suggestion is if you want to upgrade, maybe can consider for older version like 17.1, 18.0 or 18.1 see if this version also give the error. If not, then it is good to go...

I am sorry for the inconvenience caused.
