11 years agoHi Miao,
Lets go back to your original reason for asking about JTAG and BIST; --- Quote Start --- Actually I'm doing some research for FPGA chip testing. I need to download the configuration file into the chip and get the inputs of the chip fixed on some specific values.(eg: there are five inputs of a circuit and these inputs are fixed on '10010') So I'm considering to edit the configuration files but I don't know whether I can achieve my purpose using tools provided by Altera. Is there any tool can be helpful? --- Quote End --- Why can't you simply drive the inputs to 10010? You can do this with an FPGA and a cable, eg., take 5 output pins, connect them to 5 input pins, and then drive the outputs. The code to control the outputs is simple to create using Qsys. Cheers, Dave
