Techniques for variable latency redundancy

A method for providing variable latency redundancy, the method comprising:

• coupling a first storage circuit in a first data path through a first multiplexer circuit to a first input of a first logic circuit, wherein the first storage circuit is in a first circuit block in an integrated circuit, and wherein a second storage circuit is coupled between the first storage circuit and the first multiplexer circuit;
• coupling a second circuit block in the integrated circuit in a second data path to a second input of the first logic circuit;
• and
• configuring the first multiplexer circuit to adjust a latency of the first data path by bypassing or coupling the second storage circuit in the first data path based on an indication of whether a redundant third circuit block is coupled between the first and second circuit blocks in at least one of the first data path or the second data path.

A computer-readable non-transitory medium storing executable instructions for providing variable latency redundancy to circuit blocks in an integrated circuit, the executable instructions comprising:

• instructions executable by a first circuit block to couple a first storage circuit in a first data path to a first input of a first logic circuit, wherein the first multiplexer circuit is coupled to an output of the first storage circuit, wherein a second storage circuit is coupled to the output of the first storage circuit and to an input of the first multiplexer circuit, and wherein the first storage circuit is in the first circuit block;
• instructions executable by a second circuit block to couple the second circuit block in a second data path to a second input of the first logic circuit;
• and
• instructions executable by the first multiplexer circuit to adjust a latency of the first data path by bypassing or coupling the second storage circuit in the first data path based on an indication of whether a redundant third circuit block is coupled between the first and second circuit blocks in at least one of the first or second data paths.
