ABSTRACT:
A programmable logic integrated circuit device is provided with enhanced capability for dynamically multiplexing signals on the device. Controllable connectors that are provided on the device for connecting any of several connector input signals to a connector output are controlled by control signals that can be programmably selected to be either constant or variable signals. If a control signal is selected to be a variable signal, then the connector controlled by that control signal can be operated as a dynamic multiplexer of the input signals to that connector. The controllable connectors may advantageously be used as the connectors that are employed for allowing several possible signal sources to effectively share a smaller of number of signal drivers.
