SoC Architecture Tradeoffs

System-level PPA budgets, power and energy tradeoffs, and signoff gates before RTL freeze.

  • 2topics
  • 9lessons

SoC architecture converts product targets into workload-weighted PPA budgets with owners by block and mode. Power, energy, and closure evidence decide which budgets survive to RTL freeze.

Learning path through the SoC tradeoff topics.
Suggested order. Budgets first, then power and energy.

Description

Time

PPA at System Level

5

System-level PPA budgets, floorplan-aware partitions, negotiation method and signoff gates.

40 min

Power and Energy for the Architect

4

Dynamic and static power, DVFS energy-delay tradeoffs, and energy per operation.

30 min

Tip

Track cumulative budget deltas against guardbands: a run of small approved exceptions can silently consume all margin.

Check yourself How do you prevent system-level PPA goals from becoming slideware?

Anchor goals to versioned budget ledgers with block owners, mode and corner metrics, and release-gate criteria that PD and STA can independently verify. The PPA at System Level topic covers the budget ledger.

Interview

Typical screening questions from this part: defending a PPA budget ledger, trading DVFS points against energy delay, explaining the energy-per-operation memory gap, and setting conditional signoff with owned residual risk.
