Course Description

02208 Test of Integrated Circuits
Plan for Lecture 10:
Testability analysis



Design for test becomes the issue, whenever test pattern generation is considered too complex or costly. The design for test problem can be formulated in terms of the questions
  • How can the testability of a circuit be quantified ?
  • How do we design testable circuits ?
  • How may we take advantage of regular structures ?
  • Can the circuit be designed to test itself ?
The lecture on testability addresses the first of these questions.
