Foundations

Beginner 6 min

What Power Integrity Means

A voltage regulator delivers a clean supply. A transistor receives something less. Defines the two fundamental loss mechanisms: resistive drop and inductive droop.

Beginner 8 min

Static IR Drop and What It Captures

Current through resistance produces a steady voltage loss that varies across the die. IR drop analysis maps this as a spatial surface.

The Power Delivery Network: Board to Transistor

Voltage travels through board planes, package traces, solder bumps, and on-die metal layers. Each stage has different impedance characteristics and timescales.

Part II

Dynamic Physics

Intermediate 12 min

Dynamic Voltage Droop

When logic switches on, it demands current faster than the network can deliver. The resulting voltage collapse is governed by inductance, not resistance.

Intermediate 10 min

The Power Grid as a Wave-Bearing Medium

At sufficient density, millions of metal segments stop looking like discrete nodes. They become a continuous surface. Voltage disturbances travel through it as waves.

Start lesson →

Intermediate 9 min

Decoupling Capacitance and Impedance Targeting

Decoupling capacitors are local charge reservoirs. Their effectiveness depends on the impedance of the loop connecting them to the load.

Part III

Scaling and Consequences

Intermediate 11 min

Why Droop Doubles Every Generation

Under constant-power scaling, faster switching at higher di/dt means L·di/dt noise doubles per generation. What was 9 mV at 180 nm becomes 144 mV at 45 nm.

Advanced 14 min

Rogue Waves and Constructive Interference

Multiple voltage disturbances arrive simultaneously. Their amplitudes add, causing collapses far beyond what any single block produces. A growing cause of silent data corruption.

Power-Integrity-Aware Floorplanning

Block placement determines current distribution, interference patterns, and grid effectiveness. Inductance-aware optimization can reduce power metal area by 30–60%.

Total Power Integrity: Analysis to Sign-Off

Total power integrity comprehends every contributor to supply noise. True-electromagnetic analysis at floorplanning prevents costly respins downstream.
