How to analyze the signal integrity of LPC2106 microntroller?

Thank you. Very Happy

Hi all

#frist: some tool can accept constrain from U and check if U violate this constran or not.Other have not then U will write out the constrain and then rout the bouard then check u'r board manually.
#second:in general tack this guide 4 U
1- decide which signal is critical , the critical signal depend on it's rise time. from rise time U can get Critical length. from U'r PCB program check if U pass this length or not.

2- if there are some signal not pass find the way to match it at the reciver, to demamd the ringing due to reflection.

3- check the distance between track pass 3W rule or not to eleminate Cross talk.
