Abstract
Various techniques are provided to implement user specified test registers locally on a PLD for use while the PLD is configured with a user design and tested. In one example, a machine-implemented method includes receiving, from an external test application, a data value at a programmable logic device (PLD) running configured user logic. The method also includes writing the data value into a test register of the PLD. The method also includes providing a control signal from the test register to the configured user logic in response to the data value. The method also includes switching operation of the configured user logic from a first test implementation to a second test implementation in response to the control signal.
