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?

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

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

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!
