Hello

I have Quartus Prime Standard edition 21.1. also my FPGA is Cyclone IV (EP4CGX150CF23C8).

Regarding the Altera Generic Quad SPI Controller 2 look at page 262:

Even EPCQA device (EPCQ128ASI16N) is not mentioned still probably this core need a quad mode of AS.

Also in Platform designer this core is greyed (when 'Show IP for all device families' is marked):

And it simply disappeared when marked 'Show IP for active device family'.

As I understand Cyclone IV is not supporting ASx4 mode.

Thank you

Alex
