This is a CPLD device, which is EEPROM based, not SRAM based. It uses a .pof file for programming, NOT a .sof file.The option you could try is a VERIFY of the programmed device versus a known .pof file, if you have one.The only other option is to reprogram the CPLD with a .pof file and do a verify after programming to validate it programmed correctly.There is no way to download a new temporary file to try it without completely reprogramming the device.

Hi Liran,Instead of selecting "Examine", can you please select "Program/Configure" for programming?Regards,YL

Hi, This card is working and i am affraid to erase the program that is already loaded to the epm7256,Examine shall not work? ​

Hi Liran Fun,Examine is not meant for programming / burning. If thats the case, i would suggest you to burn SOF file into the device as it is volatile.Regards,YL
