JTAG and AS configuration on Cyclone IV

Hi, I am making a circuit with Cyclone IV and I see various schematics. I would like to understand if I can only use the AS connector in my circuit, and in this case, can I leave the lines...

Yes you can capture a board with only AS programming. However, I wouldn't. JTAG can prove very useful.

I agree with FvM - this is what I do regularly. Only connect up JTAG and program your configuration device via the FPGA using a .jic file (JTAG Indirect Configuration).

Refer to an 370: using the intel fpga serial flash loader with the intel quartus prime software (https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/an/an370.pdf) which discusses this in detail.

Cheers,

Alex
