EEL 6232 W.R. Eisenstadt Test for CMOS ICs SEE Rabaey p. 721 to 738 Why Test? o o o o o High cost of IC failure in the field, (rough example) Cost of IC failure at wafer level $1.00 Cost of IC failure at Package level $2.00 Cost of IC failure at board level $20.00 Cost of IC failure at system level $200.00 Cost of IC failure at field level $2000.00 Systems manufacturers demand virtually no IC failures to keep warranty costs under control. IC manufacturers who have poor quality are delegated to second-tier sources and receive low prices for their chips. Consumers who buy failed electronics look for different systems manufacturers. IC test is the primary way of reducing the number of IC failures in the field to acceptable levels. So what is IC test? This is confusing because IC test means many things to many people in industry. Bench test -Students are very familiar with the concept of bench test. This is where the electronic measurement equipment is assembled such as logic analyzers, oscilloscopes, etc. on a Lab bench and experiments are done on the IC. Bench test is used by the IC designer in and the IC test engineer to verify the functionality of the design. Thus, the first IC prototypes are examined in minute detail in
