problem in program the EPCS16 with jic file in a multiple-FPGA system.

[Altera_Forum]

Dear all, 

In board, there are two EP3C25Q240, they are designed with multi-device AS and JTAG configuration. A EPCS16 is used to configure the two FPGAs.  In Jtag mode, I can download the sof file, and they works.  However, in the AS mode, when I configure the EPCS16 with a pof file, the error "can't recognize silicon ID for device 1 ".  So I try to program the EPCS16 with JTAG through SFL using jic file.  As there are two FPGAs, so I have to change two pof file to jic file. But I donn't know whether I should combine two pof files into one jic file, or change two pof files into two jic files seperately.  I have tried programe the two fpgas with two jic files, but there is a error" conf_done pin failed to go high in device 2"  Have anyone have experiences in this case? Thanks for any suggestions

hi, 

you can do that with convert programmer files tool under QII's file menu.

Thank you,Jerry. 

yes, I can get the jic files with convert programmer files tool under QII's file menu. In my case, there are two FPGAs, and one configuration device (EPCS16). Should I convert two sof files (for two FPGAs) into a single jic file? or should I convert two sof files into seperate jic files? I was a bit confused.

2 sof files to 1 jic file!
