I'm interested in calculating series termination resistors for my communication lines for a system I'm designing based on the Zynq-7000 SoC. The system runs on a 33 MHz clock but I'm sure the bandwidths I need to consider are much greater due to the rise time of the signals (I'm interested in just the processor right now). I tried looking for rise times of this SoC's signals, and even tried to find it for generic ARM cortex A9 processors, but wasn't able to come up with anything.
How would I go about finding the rise time to ensure the termination resistance I implement are appropriate for my system?
