Configurable storage elements

A method of operating a configurable routing fabric of an integrated circuit (IC), the method comprising:

• defining a first configuration data for a configurable routing circuit in the configurable routing fabric, the configurable routing circuit comprising a plurality of parallel paths that each comprises a latch for storing signals form an output of a source circuit to inputs of a destination circuit, wherein a first path comprises a first latch that is controlled by the first configuration data and a second path comprises a second latch that is controlled by an inverted value of the first configuration data;
• and
• defining a second configuration data for the destination circuit to select between a signal from the first path and a signal from the second path as an output of the configurable routing circuit, wherein the configurable routing circuit acts as a double edge triggered flip-flop when the first and second configuration data change simultaneously while the second configuration data controls the destination circuit to select a path that comprises a closed latch.

• defining a second configuration data for the destination circuit to select between a signal form the first path and a signal form the second path as an output of the configurable routing circuit, wherein the configurable routing circuit acts (i) as a transparent signal path when the second configuration data controls the destination circuit to select a path that comprises an open latch and (ii) as a storage element when the second configuration data controls the destination circuit to select a path that comprises a closed latch.
