Testing of Digital Systems


According to the International Technology Roadmap for Semiconductors (ITRS-2008 update), for more than four decades, the semiconductor industry has distinguish itself by the rapid pace of improvements in its products. However, the cost of the increased functionality of components, circuits, and ultimately systems, is the requirement of more verification and test of the electronic products. 

In many digital application domains the verification of the design has become the predominant component of a project’s development in terms of time, cost and the human resources dedicated to it.

In current projects, verification engineers outnumber designers, with the ratio reaching two or three to one for the most complex designs. Problems associated with digital logic testing have existed for as long as digital logic itself has existed. Industry indicates a severe shortage of test engineers because few universities have test engineering courses to address this need.  



Catalog Description: Introduction to testing; Test economics; Automatic Testing Equipment; Fault Modeling; Testing Algorithms for Combinational and Sequential circuits; Design for Testability.

Course objectives

  • To understand the concept of  electronic testing
  • To understand techniques for generating tests for faults in combinational and sequential circuits and automated techniques for evaluating those tests.
  • To understand techniques that can be used by the designer to make testing a circuit for faults possible and economical.
  • To learn techniques for building in test capability in a circuit.
