Title: substrate coupling analysis
Post by ywguo on Jun 6^th, 2007, 12:50am

Hello, guys,

Would you please recommend any software to analyze the substrate coupling? I need a software to assist the floor plan which composed of RF transceiver, analog baseband, and some digital filters.

Thank you.
Yawei

Hi,
I didn't have many experience with this kind of tools but at my lab signal integrity guys are working with WaveIntegrity^Tm, the website of this product is:http://www.cwseda.com/, one of the creators is François CLEMENT who was also involved in the SUBSTRATE STORM development.
As I said I don't have many experience with these tool, if I could talk to one of the labmates and ask his opinion I will post any references here.
Good Luck.

Probably late for this party, but I've seen demos of the Cadence Assura HF option which is the substrate analysis option package of the Assura Suite. That looked impressive and my design group is beginning to use and evaluate the performance/accuracy.

You could do things like add an aggessor ac voltage source on the extracted layout and look graphically @ the coupling to various points on the layout. You could also see graphically the influence of different guard rings schemes and such. The key thing is to have extraction decks (models) for this tool to work. Otherwise, it integrates well into the overall cadence design methodology.
