Abstract
An integrated circuit includes a clock macro circuit. The clock macro circuit includes first, second, and third latch circuits and a multiplexer circuit. The first latch circuit is coupled to the second latch circuit. The multiplexer circuit is coupled to the second and third latch circuits. The clock macro circuit includes programmable vias that are programmed during fabrication of the integrated circuit to couple inputs of the clock macro circuit to the first latch circuit, the second latch circuit, the third latch circuit, and the multiplexer circuit. Programming the programmable vias causes the clock macro circuit to function as a selected type of clock circuit.
