摘要：
A programmable logic device is provided that contains circuitry that may be used for observing logic signals from programmable logic circuits on the device for testing the operation of the device. Circuitry is also provided that may be used for preloading data into various circuits on the device. The logic signal observing circuitry may allow registered signals to be observed, may allow combinatorial signals to be observed, or may allow both registered and combinatorial signals to be observed.
