New ContributorI used EPCQ16ASI8N to replace EPCS16SI8N, but I found out that I can't burn the program.I found in the datasheet that the structure of EPCS16SI8N is AS × 1, EPCQ16ASI8N has AS × 1 and AS × 4.The ordering code of EPCQ16 is only EPCQ16ASI8N. How do I judge the structure I bought?
ContributorThe EPCQ16 supports all the operations that the EPCS16 does. It will also work quite happily in x1 mode. So, yes - you should be able to use the EPCQ16 in place of your old EPCS16.
You don't say what tools/software you're using to program the device. The EPCQ and EPCS devices will have different identifiers. Some programmers - e.g. the nios-flash-programmer software - simply refuse to program a device whose identifier it doesn't recognise.

New ContributorI use Quartus II to program the device. I see that there is a way to enable the Disable EPCS/EPCQ ID check option in guidance, but the software used is Quartus Prime. How do I use Quartus II to block ID checks?
Thank you for your help.

ContributorYou have to disable the check via the 'Convert Programming Files...' window. Click on the 'Advanced' button.
