The document discusses a power delivery network (PDN) verification flow to analyze power, noise, and reliability for advanced electronic systems. The flow aims to provide high design failure coverage through early detection of faults and weaknesses, enabling early prototyping and improvement of productivity. It involves checks for design weaknesses, static simulation, scan and gate-level vectorless simulation incorporating package and decap effects to thoroughly test designs under different conditions.

Design weakness
check
 Check that metal density can supply
the design estimated average current
Check pad’s and power gates count and location
Static
Simulation
 Checking the design in maximum peak stress test
Scan
RTL VCD  VCD simulation with low effort in preparing the VCD,
state propagation is done by RedHawk
Worst power cycle selection
 Gate Level VCD with true timing for maximum real
case simulation and silicon correlation
GL VCD
 High coverage in detecting design weaknesses:
 High frequency
Simultaneous switching
Poor power grid connectivity
Multi cycle vectorless simulation
Simulating Package and Decaps effect
