Abstract

The proposed functional test method for complex circuits presents the following features: - the test problem is studied in the aggregate; a test method, a test environment and automated test program generation are proposed. - the circuit behavior is considered as a whole. including the response to instructions (or commands). and to signals at the same level. Emphasis is put on the signal test: an hardware which allows the test of signals and is compatible with functional testing is defined; a description language for signal timing diagrams is proposed.
