12 years ago --- Quote Start --- I have Terasic Cyclone II FPGA Start Board. --- Quote End --- Ok. http://www.terasic.com.tw/cgi-bin/page/archive.pl?language=english&categoryno=53&no=83 --- Quote Start --- I have to build complete board that includes the FPGA. If this FPGA custom board works, I just replace the FPGA on real system. --- Quote End --- The comment "I just replace the FPGA on real system" makes no sense. You cannot "just replace" an FPGA. BGA devices require special rework machines. What is it you are really trying to say? Please explain your application and why the Terasic board does not meet your needs. --- Quote Start --- I couldn't find document of pin layout. I look at Pin Planner in Quartus II, but I don't see how the USB JTAG connect to FPGA. Is that go through GPIO or special wires? --- Quote End --- These are basic questions that have multiple answers; the Altera web site has the pin assignments for each FPGA in a particular package, the DE1 schematic will show you the pin assignments of this specific board, and the pin planner should have those pins shown on the graphic of the device. My impression is that designing an FPGA board from scratch will be challenging for you. I would recommend considering designing an interface board that plugs into your DE1 board. Cheers, Dave
