Hi,
I want to control a 16 bit DDR module with the 256 pin Spartan-3e 500 package. There are too many pins on the DDR to fit in one quadrant of the device, so it will have to use 2. Can this work? I was thinking address and control lines on one quadrant, and the data on another.
The 320 pin package brings out enough IO so that a single quadrant can control everything, but that's more expensive.
I'm wondering if the timing will be ok (100 mhz or faster is what I'm shooting for) with the logic spread across quadrants.
Thanks-- Dave
