Honored Contributorquestions: PS configuration of cyclone3 EP3C5F256
I'm working on my first design with an FPGA, and am just ready to send out files to have prototype PCBs made. I just realized I might not understand the details of how PS (passive serial) configurat...

Honored ContributorTrying to further clarify some points:
- You have to write the complete configuration bitstream, as contained in the *.rbf file, otherwise the configuration will fail. - Altera doesn't support partial reconfiguration for any FPGA family up to now - A design with low LE count will considerably shrink in compressed mode (e.g. to 1/3 of original size). The compression algorithm is however designed for compact implementation in FPGA hardware and doesn't achieve results comparable to e.g. ZIP. To minimize flash memory footprint, you may want to apply an additional software compression/decompression in your application.
