Area, Power and Test

Area, power and timing trade-offs, clock gating, and scan insertion.

  • 3topics
  • 14lessons

This part weighs the full result after datapath and timing are built. Fair comparison across area, power, and timing picks the winning run, while clock gating and isolation trim power. Scan insertion then keeps the netlist testable at a stated area and timing cost.

Learning path through the area, power and test topics.
Suggested order. Trade-offs first, then low power, then test.

Description

Time

Area, Power and Timing Trade-offs

5

Comparing two runs fairly across area, power, and timing.

40 min

Clock Gating and Low Power

5

Latch-based clock gating, operand isolation, and power intent as concepts.

40 min

DFT and Scan Insertion

4

Scan flops, chains, DFT-friendly RTL, balancing, and scan overhead.

32 min

Tip

Quote power with the activity assumption attached: alpha, capacitance, voltage, and frequency are stated example parameters, never hidden defaults.

Check yourself Two runs tie on timing. How do you pick the winner?

Compare area and power at that timing with stated numbers, and drop any option another beats on every axis. The Area, Power and Timing Trade-offs topic works the filter.

Interview

Typical screening questions from this part: dynamic power arithmetic, why latch-based gating beats AND gating, and what makes RTL DFT-friendly.
