Hi Karthikeyan,
Below document helps to you.
"Addressing Crosstalk in High Speed Designs Using Allegro PCB SI."
You can find Allegro installation directory or web.
In pre-layout phase, you must draw coupled topology (microstrip or
stripline,3 4 5 coupling line ), you can play spacing, impedance, coupled
length, agressors .... In routing phase, you can define many constraints in
the CM. Max parallel (wiring tab) and active-sensitive windows (xtalk tab).
And you must play geometry window and min coupled length (interconnect model
tab) for allegro searching neighbouring nets. And finally you must generate
detailed crosstalk reports. Now, crosstalk can not damage to your design.
And I suggested to read CDNLive 2005 paper " Estimated XTALK Implementation
& Checking" from CISCO. You can find Cadence website.

Subject: [SI-LIST] Xtalk analysis in SPECCTRAQuest
Dear All,
Can any one help me to do the Xtalk analysis in Allegro PCB SI 630
(SPECCTRAQuest). I want to know the step by step produre and the constraints
we have to set for the simulation. and How to do the analysis from the
report to reduce the xtalk ??
Thanks in advance,
yours
karthikeyan
