For a Cyclone EP1C20, the config file size is 3.56 M-bits.

The maximum DCLK frequency Cyclone supports is 66 MHz; so 1/66M * 3.56 M-bit = 54ms

This does not take into account any overhead in the code, as well as the fact that your 8-bit micro probably can't toggle it's GPIO at 66 MHz.....

Hope this helps.
