LSI design flow and EDA

In analog circuit design, which technique repeatedly simulates with randomly applied transistor variations from manufacturing to estimate performance distributions and yield?

  1. AMonte Carlo simulation
  2. BLogic synthesis
  3. CDicing
Show answer and explanation

Answer: A. Monte Carlo simulation

Monte Carlo simulation repeats circuit simulation hundreds or thousands of times while varying parameters such as threshold voltage with random numbers, based on the PDK's variation models. From the distributions of offset voltage, gain and the like, the fraction meeting specifications (parametric yield) can be estimated.

  • A. Correct. It repeats simulations with random variations applied.
  • B. Logic synthesis generates gate-level circuits from RTL.
  • C. Dicing separates the wafer into chips.
