o Static IR Drop Analysis: Calculates the average voltage drop across the PDN based on average current consumption (leakage + average switching).
o
Dynamic IR Drop Analysis (Voltage Droop):
Simulates transient voltage drops based on switching activity.
o
Power/Ground EM Analysis: Checks for
electromigration violations (average, RMS, peak current density) on the VDD and
VSS network wires and vias based on calculated currents.
o
Signal EM Analysis: Checks for EM
violations on signal interconnects, which is increasingly important at advanced
nodes.
o
Electrothermal Co-simulation (RedHawk-SC
Electrothermal): Simulates the interaction between power dissipation,
temperature, and electrical performance (IR drop, EM limits are
temperature-dependent).
o
Timing Impact Analysis (with Path FX):
Can analyze how voltage variations (IR drop) impact the timing of critical
paths.
