Configure Cyclone with Flash and PIC

Hi @ all!

Has anyone tried to configure Cyclone on bootup wit a simple 8-Bit-µC?

Is there an example available ?

I've seen some posts in different forums about a CPLD-solution, but no example for Altera. How much will a CPLD solution cost?

ASD is not possible, because I've different configurations for the Cyclone.

    Thank's first!

    Do anyone have experience how long it need's to configure a 20k LE's Cyclone Device with PS. Doku say's only: Moderate. What is moderate? 1ms, 100ms, 1s, 10s?

    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.
