Power Integrity and IR Drop Analysis Training

About Course

Ansys RedHawk training is a 8 weeks training program targeted for standard power noise and reliability sign-off solution for SOC designs. RedHawk helps create high-performance SoCs which are power efficient and reliable for electromigration, thermal and electrostatic discharge issues. RedHawk is the sign-off solution for all the foundries. RedHawk’s advanced Distributed Machine Processing (DMP) enables significantly higher capacity and better performance for full-chip IR/dynamic voltage drop, power/signal electromigration (EM) and electrostatic discharge (ESD) analyses.

RedHawk training will focus on all the aspects Power integrity, and IR drop analysis.
