14 years agoonchip memory timing constraints
Hi guys! I am capturing 1Mbit of 64 bit words at 100MHz with onchip memory on my DE2-115 board. All data is produced on the chip. How do I need to add timing constraints? Do I need to set...

14 years agoIf your design is fully included in fpga (I mean if you only use onchip memory and no external ram or other i/o interfaces with timing requirements) then you only need a few timing constraints.
Did you read the TimeQuest tutorial? You can also refer to the TQ guide by Rysc, which is very clear; you'll find it on the Wiki. The number of bits/word depends on your implementation. IIRC M9k blocks support up to 36bit width, but you can read more of them in parallel to emulate wider ports.
