| 1. A programmable logic device, comprising:
a plurality of programmable resources;
non-volatile configuration to store configuration data for configuring the plurality of programmable resources; and
test-override circuitry operable to determine a test mode and selectively operable dependent upon the test mode determination
to override by bypassing the configuration data stored in the non-volatile configuration memory and configure at least one
of the plurality of programmable resources based on test data of a source different from the configuration data stored in
the non-volatile configuration memory.
