Abstract
A tester (10) for testing an electronic circuit (22) has test terminals (18a-d) that are to be connected to the terminals (20a-d) of the circuit under test. The tester terminals (18a-d) are placed in the states required for testing by formatter circuits (32a-d) in accordance with state codes generated by state-code generators (24a-d). However, the state-code generators (24a-d) are not required to generate every code as quickly as those codes are needed by the formatters (32a-d), because first-in, first-out memory stacks (30a-d) are interposed between the state-code generators (24a-d) and the formatters (32a-d). This permits the state-code generators (24a-d) to employ relatively slow--and thus relatively inexpensive--memories (26).
