Got enough metal? Be sure you have enough copper planes, traces, and vias on your PCB to carry all the DC current to your ICs. HyperLynx PI allows you to quickly identify problems with voltage drop and current density for all the voltage rails on your PCB. PDNs can be exported to HyperLynx LineSim for complete what-if experimentation, including changing plane shapes and/or traces, adding vias, and viewing the effects of those changes.
