My software department manager want to add this feature to be able to verify the FPGA contents. Maybe if I can find the 100% guarantee that the FPGA's contents do not change over time given the fact that power supply is not interrupted, I might be able to convince my manager that the verify option is not neccessary. But for this moment, I am curious myself about how to do this. I searched for the user manual, but all I have is the Cyclone II Device Handbook (All Sections) (downloaded from link http://www.altera.com/literature/hb/cyc2/cyc2_cii5v1.pdf last thursday). I cannot find the section you mention also the searchterm "SEU" in this almost 800 page document does not deliver any search result. I did some further searching and stumbled accross this document : http://www.altera.com/literature/an/an357.pdf. It explains CRC error checking, using the JTAG interface. Is this document what you mean ? How can it be done without JTAG ? It does not state how to read-out the current configuration..... Can you please specify a link to the document you are referring to ? Not having source code might not be a problem. When the explanation is detailed, I can manage. Thanks, Bart
