Hi,

Thanks for the answer.

I would like to identify EPCS16, EPCQ32 and EPCS64

We are also using arriaV which has little bit different programming style to empty memory.

We use also other FPGAs as well.

Programming is done external MCU to the memory. The one MCU code is used for all the FPGA and meories and we would really like to see the

memory type we are facing by reading some info from the memory.

I think that EPCS don't support (except 128) "Read device Identification" and EPCQ doesn't support "Read Silicon ID", am I correct ?

What do they return if "Read silicon ID" is used for EPCQ and "Read device Identification" for EPCS ?

So what is the return value for the reads that aren't meant for them ?

Do they return always same value ?

Of cource we could read always both "Read device Identification" and "Read Silicon ID" but is there a change that we could get mixed by determining what is the memory we are up against ?
