I use PCB SI, and try to simulation using PCB SI.
So I download the Allegro PCB SI User Guide(ver.16.6).
But there are many other documents to get a detail information. (ex. Allegro SI SigWave User Guide, Allegro PCB PDN Analysis User Guide, etc)
Where can I download the other documents?
To access cadence Internet Learning Series courses, log into https://Support.Cadence.com
Click on >Learning at the top, then >Online Courses on the left. Type PCB SI in the search bar.
Another options is the Rapid Adoption Kits.
I used "RAK SI" as a search term while logged into the support website.. 20 different application notes and test databases. Hours of fun.
