14 years agoConfig compression makes no difference
I ran my Cyclone 3 design with and without compressed config file generation & in both cases the .sof file came out to be 350KB. No change with compression. Did I miss some Quartus setti...

12 years ago --- Quote Start --- There are more cells in the EP4CGX150, so the uncompressed bitstream will be bigger, even if you aren't using most of them. As a result the compressed bitstream will be a bit bigger too. --- Quote End --- According to *.map file the *.pof and *.*.jic files for EP4CGX150+EPCS128 are 3 times bigger, then for EP4CGX22+EPCS4! Could it be such a big difference? As a result I cannot test the project targeted for a custom board with EP4CGX22+EPCS4 on Cyclone IV GX FPGA Development Kit which has EP4CGX150+EPCS128 because PCIe wake-up time is violated because *.pof and *.*.jic files for EP4CGX150+EPCS128 being too big.... Is there any workaround?
