Abstract
A method of testing a large integrated circuit (10) of modular design. Test equipment is connected to a dedicated testing pad section (20) for each circuit section (22, 24, 34) of each module (12, 14, 16). The circuit section under test is tested via the testing pad adjacent that circuit section. The test equipment is then stepped to the testing section for the next circuit section. When testing is completed, the testing section is then electrically isolated from the circuit sections to prevent interference with operation of the entire circuit (10).
