Abstract:
1. A method for pipelined direct-drive routing in a programmable logic device, the method comprising: programming a mode multiplexer to a pipeline mode, the mode multiplexer comprising a first tri-state buffer, and the mode multiplexer having first and second inputs and an output; selecting the signal by a routing multiplexer, the routing multiplexer having multiple inputs and an output, wherein the output of the routing multiplexer is connected to the first input of the mode multiplexer; outputting the signal from the output of the routing multiplexer to an input of a flip-flop; delaying the signal by the flip-flop; outputting the signal from an output of the flip-flop to a second input of the mode multiplexer; and outputting the signal from the mode multiplexer to a driver circuit.
