Dave,

Nice paper and thanks.

FvM,

I am looking at PS mode because of the configuration time boost. AS mode on Stratix IV runs somewhere between 17MHz to 40MHz. PS mode can run up to 125MHz. Because of design constraints, I cannot do FPP and my Nios II code will also be stored in this same FLASH chip. I agree that AS mode is much easier as it is direct connect no-brainer but the configuration time is just too slow. It's too bad that Altera does not allow for a pin to be driven by an external clock to be used as the AS DCLK.
