28 Apr 1996TL;DR: The validity of the proposed test method has been verified throughout some examples such as operational amplifiers and analog-to-digital converter (ADC), which imply that oscillation-test strategy is very attractive for wafer-probe testing as well as final production testing.
Abstract: A new low-cost test method for analog integrated circuits, called oscillation-test, is presented. During the test mode, the circuit under test (CUT) is converted to a circuit that oscillates. Faults in the CUT which cause a reasonable deviation of the oscillation frequency from its nominal value can be detected. Using this test method, no test vector is required to be applied. Therefore, the test vector generation problem is eliminated and the test time is very small because a limited number of oscillation frequencies is evaluated for each CUT. Due to its digital nature, the oscillation frequency can be easily interfaced to boundary scan. This characteristics imply that oscillation-test strategy is very attractive for wafer-probe testing as well as final production testing. In this paper, the validity of the proposed test method has been verified throughout some examples such as operational amplifiers and analog-to-digital converter (ADC).

TL;DR: The program has successfully produced sets of delay tests for large logic networks and the average coverage achieved by these tests faDs within 95.8 percent to 99.9 percent of optimal.
Abstract: Delay testing is a test procedure to verify the timing performance of manufactured logic networks. When a level-sensitive scan design (LSSD) discipline is used, all networks are combinational. Appropriate test patterns are selected on the basis of certain theoretical criteria. These criteria are embodied in an experimental test generation program. The program has successfully produced sets of delay tests for large logic networks. The average coverage achieved by these tests faDs within 95.8 percent to 99.9 percent of optimal.

TL;DR: The authors devise an efficient test procedure for the interconnect structure and demonstrate its applicability to commercial FPGAs.
Abstract: Testing FPGAs before user programming can be an expensive procedure. Applying their general test configuration and test pattern generation methodology, the authors devise an efficient test procedure for the interconnect structure and demonstrate its applicability to commercial FPGAs.

TL;DR: New strategies where at-speed scan tests can be applied with internal PLL and methodologies to combine both stuck-at-fault and delay-test vectors into an effective test suite are described.
Abstract: The authors describe new strategies where at-speed scan tests can be applied with internal PLL. They present techniques for optimizing ATPG across multiple clock domains and methodologies to combine both stuck-at-fault and delay-test vectors into an effective test suite.

TL;DR: It has been shown, for a fanout free circuit under test, that the transition test generation cost for a fault is the minimum number of transitions required to test a given stuck-at fault.
Abstract: A automatic test pattern generator (ATPG) algorithm is proposed that reduces switching activity (between successive test vectors) during test application. The main objective is to permit safe and inexpensive testing of low power circuits and bare die that might otherwise require expensive heat removal equipment for testing at high speeds, Three new cost functions, namely transition controllability, observability, and test generation costs, have been defined. It has been shown, for a fanout free circuit under test, that the transition test generation cost for a fault is the minimum number of transitions required to test a given stuck-at fault. The proposed algorithm has been implemented and the generated tests are compared with those generated by a standard PODEM implementation for the larger ISCAS85 benchmark circuits. The results clearly demonstrate that the tests generated using the proposed ATPG can decrease the average number of (weighted) transitions between successive test vectors by a factor of 2 to 23.
