LSI design flow and EDA

Which set correctly gives the three metrics represented by "PPA", often used to evaluate LSI designs?

  1. APressure, power and angle
  2. BPerformance, power and area
  3. CPrice, profit and advertising
Show answer and explanation

Answer: B. Performance, power and area

PPA stands for performance (such as operating speed), power consumption and chip area, the basic metrics for comparing designs and processes. They often trade off against each other, so designs balance them according to the application.

  • A. It is not pressure or angle.
  • B. Correct. Performance, power and area.
  • C. Price and profit are not the design metric PPA.
