I'm trying to do a project that involves taking in data at a decent rate(50-100MHz), but I'm a poor college student who can't afford software packages worth thousands of dollars to do signal integrity analysis. The ibis data seems straight forward enough, but I was wondering if anyone knows how the constraints, and or static timing information relates to these ibis data points. For example:
-does the Xilinx static timing information tell how long the signal on an input has to remain stable in order to be sampled correctly.
-When data is being send out on a pin do I assume that the output starts to transition after the pad delay, or does the clock to pad delay give you when the ibis VT curve reaches some threshold like 50% or 90% VCC.
Pointing me in the right direction on these issues would really help me out.
