0:10 How is the Cadence development office related to the offices in the Valley?
0:41 What can you tell me about the history of Allegro?
1:01 What is the latest on the signal integrity tools that are now cohabiting along with the Allegro design?
2:12 Has the incorporation of signal integrity tools and infrastructure in an ECAD environment become almost a necessity?
