IC designs have been growing exponentially in size but the number of pins have not kept the same pace. This imbalance poses a difficult challenge when a design has very limited number of test pins but still requires a high quality testing. This problem is exacerbated when additional fault models like transition delay fault model are required for testing. This paper describes how a low pin count test controller was able to meet all these requirements to test a pin limited transceiver chip used in Qualcomm Technologies Inc.'s state-of-the-art chipset. The low pin count test controller supports at-speed testing with on-chip clock controller and exceeded the test coverage requirements for both stuck-at and at-speed testing by 1.22% and 2.16% respectively. During wafer testing, this test-pin savings enabled higher parallel testing of dies using multi-site testing which reduced the test-costs by about 1.6x. |
