IR drop and EM issues are significant performance and reliability detractors at advanced nodes. Adding vias is the most effective means of correction, but traditional custom scripts are difficult and time-consuming, and do not guarantee correct-by-construction vias. The Calibe YieldEnhancer PowerVia utility uses manufacturing requirements to perform automated insertion of DRC/LVS-clean vias. Results show significant improvements in EM/IR results, including substantial reductions in current density violations.
