    I have written state machines for factory and application images -cyclone3-AS mode-EPCS16.

    Do I need ALTASMI mega function to connect serial device(I2C)?

    I read that there is no need of ALTASMI.But,how the data transfer takes place between I2C and EPCS?

    How do I build SOPC?Greatly appreciate if anyone can guide me!

    Decrease the on-chip RAM size, from 40k to something like 32k or 28k. The other components can stay the same.

    sorry,

    about web "www . grigaitis.eu/?p=514", that is use on the EP3C25.

    because of the EP3C16 internal memory less then EP3C25,

    so i need to modify memory setting, but i don't understand how to modify.

    so have any document give me reference.

    and have any docutment or Explame or source code(use on EP3C16 + EPCS + AS mode + UART) give me reference.

    thanks

    I don't understand your question... Your link already gives all the details, and provide example hardware and software designs. What do you need more?
