LSI design flow and EDA

In developing large LSIs, which activity is said to take a large share of the total effort?

  1. AChoosing the chip's color
  2. BPrinting markings on the package
  3. CVerification that the design works correctly to specification
Show answer and explanation

Answer: C. Verification that the design works correctly to specification

Once an LSI is manufactured it cannot easily be fixed, and remaking masks costs much money and time. Verification to eliminate design errors before manufacturing is therefore crucial, and in large SoCs it is said to account for more than half of development effort.

  • A. There is no task of choosing the chip's color.
  • B. Marking is a short step.
  • C. Correct. Verification takes a large share.
