摘要： Test circuits located on semiconductor die enable a tester to test a plurality of die/ICs in parallel by inputting both stimulus and response patterns to the plurality of die/ICs. The response patterns from the tester are input to the test circuits along with the output response of the die/IC to be compared. Also disclosed is the use of a response signal encoding scheme whereby the tester transmits response test commands to the test circuits, using a single signal per test circuit, to perform: (1) a compare die/IC output against an expected logic high, (2) a compare die/IC output against an expected logic low, and (3) a mask compare operation. The use of the signal encoding scheme allows functional testing of die and ICs since all response test commands (i.e. 1-3 above) required at each die/IC output can be transmitted to each die/IC output using only a single tester signal connection per die/IC output. In addition to functional testing, scan testing of die and ICs is also possible.
