Abstract

See full text

Method and system for testing circuitry of a programmable logic device (PLD). A host data processing arrangement is configured with a run-time reconfiguration programming interface, and a run-time reconfiguration test program that invokes methods of the interface executes on the host arrangement. In response to a method of the programming interface invoked from the test program, the PLD is configured with a first configuration bitstream. State data are then read back from the PLD in response to a method of the programming interface invoked from the test program. The test program also identifies differences between the state data and expected-results data.
