Using FPP mode in Quartus II for Cyclone IV devices

I am taking over an old project at work using a Cyclone IV device (EP4CGX150F23C7N). I can get it to compile just fine which makes and .sof file. We need to convert it to a .pof file since we are usi...

I assumed the same thing, that maybe they just dropped the 'fast' part and are now calling it Passive Parallel.

The passive parallel x8 mode does appear in the mode drop down, but when I click the generate button I get a pop up window with the message 'Device EP4CGX150CF23 does not support Passive Parallel x8 scheme'.

This is what makes me think there might be a setting wrong somewhere in the project, because I know this device supports that mode. In fact I just programmed it using that mode with the pof file I generated in the 12.0 software and it is working just fine.

I dont believe we have a licensing issue - our SW license is current. We are using the Qsys PCI IP, and other then that just some basic megafunctions and I did not think any of that needed a separate license. But I am just getting up to speed with this - I will look into the licensing issue a bit more.

I already have an open service request with Altera but so far they have not responded with anything helpful...

Thanks for the reply!
