ABSTRACT:
Circuit for selectively using static or dynamic select signals inside an integrated circuit, including a first transistor connecting a static select signal to a dynamic route select output line when a dynamic select CRAM signal is at a first logical level, and a second transistor connecting a dynamic select signal to the dynamic route select output line when the dynamic select CRAM signal is at a second logical level. The circuit further comprises a dynamic select CRAM register that contains a logical value to indicate whether the dynamic select signal bypasses the static select signal. The dynamic select CRAM register is connected to the second transistor gate, and to an inverter whose output is connected to the first transistor gate.
