  • Patent number: 8639992
    Abstract: The soft error rate (SER) detector circuit presented here can be used to measure SER in combinatorial logic devices caused by radiation. The SER detector circuit includes a plurality of detector arrays coupled in series, and each having a plurality of SER test structures coupled in series. Each of the SER test structures includes a plurality of detector elements coupled in series. Each of the SER test structures is configured to detect single event transients (SETs) in a first operating mode and single event upsets (SEUs) in a second operating mode. The SER detector circuit also has control logic elements to control operation of the plurality of detector arrays.

  • Patent number: 8549369
    Abstract: A semiconductor-based test device includes a plurality of testing clusters and a pseudorandom global stimulus source coupled to the testing clusters. Each testing cluster includes a plurality of data registers and logic elements configured to perform random logic functions for generating test data for the plurality of data registers. The pseudorandom global stimulus source generates a pseudorandom binary stimulus for the logic elements. At least some of the plurality of testing clusters are coupled together to support inter-cluster fan-out and fan-in of data register output.

  • Patent number: 8095331
    Abstract: In a transaction-based verification environment for complex semiconductor devices, enhanced verification efficiency may be achieved by providing a transaction to machine code translator and an appropriate interface that enables access of the translated machine code instruction by a CPU under test. In this manner, transaction-based test environments may have a high degree of re-usability and may be used for verification on block level and system level.
