Signal integrity analysis of PCBs
« on: November 25, 2017, 02:42:38 AM »

I am new to signal integrity concept and wanted to know about signal integrity analyses for a 25 MHz range FPGA based PCB. What all are to be checked for SI analyses and how can it be done. I know the usage of CST microwave. Will that be helpful pls.? It will be nice if anyone can list the analyses/ checks to be made for SI in PCBs as a starting point of my search.

For something as slow as 25MHz, my basic questions would be 'is everything run over a solid continuous reference plane' and 'have you controlled the edge rates'? 

Get those right, get the power decoupling reasonable and your basically covered for SI given you are doing wiggly DC sort of rates.
