Abstract
A hardware controller of a device under test (DUT) communicates with a PCIe controller to fetch test data and control test execution. The hardware controller also communicates with a JTAG/IEEE 1500 component to set up the DUT into various test configurations and to trigger test execution. For SCAN tests, the hardware controller provides a high throughput direct access to the on-chip compressors/decompressors to load the scan data and to collect the test results.
