13 years ago --- Quote Start --- After I try to configure the two FPGAs, they both work. (CONF_DONE signal goes high after two FPGAs are configured.) --- Quote End --- Ok. Can you confirm that your hardware works, i.e., once both of these FPGAs configured, could you tell that they entered user mode, eg., could you blink an LED on each FPGA, or perhaps access a JTAG component internal to the designs? --- Quote Start --- So now I'm trying to download jic and pof file into the epcs. (jic and pof files are converted from the sof file) For jic file, I connect the usb blaster to the JTAG header. For pof file, I connect the usb blaster to other header for AS mode configuration. Again, the Quartus II programmer shows me "success" but the FPGA doesn't work. CONF_DONE signal is low. --- Quote End --- This statement is confusing. You stated above that you had two JTAG headers on your board. Are you re-stating now that one is a JTAG header and the other is an Active Serial header? The two headers are identical, but the connections on the PCB are not. Could you post a schematic of the design, or if this is an evaluation board, post a link to its documentation. Programming an EPCS can be performed using an AS header, or via JTAG using SFL. Why do you think you need both a .jic file and a .pof file? Cheers, Dave
