Abstract
One embodiment relates to a circuit for pipelined direct-drive routing, the circuit including a routing multiplexer, a flip-flop, and a mode multiplexer. The output of the routing multiplexer is coupled to an input of the mode multiplexer and to the flip-flop. The output of the flip-flop is connected to another input of the mode multiplexer. The flip-flop may be directly connected to the routing multiplexer and the mode multiplexer, or, in an alternate embodiment, the flip-flop may be a member of a pipeline register pool. Another embodiment relates to a circuit for pipelined direct-drive routing which uses a pulse latch. Other embodiments relate to method for pipelined direct-drive routing which includes a degree of logical separation between logic elements and flip-flop elements. Another embodiment relates to a logic array block. Other embodiments, aspects, and features are also disclosed.
