Abstract:
1. An integrated circuit (“IC”) comprising: a plurality of configurable logic circuits for configurably performing a plurality of logic operations based on configuration data; and a configurable routing fabric for configurably routing signals among the configurable logic circuits, the configurable routing fabric comprising a particular wiring path connecting an output of a source circuit to inputs of a destination circuit, the particular wiring path controlled by a first configuration data and the destination circuit controlled by a second configuration data, wherein the particular wiring path comprises first and second parallel paths respectively connected to the first and second inputs of the destination circuit and comprising respectively first and second latches, wherein the first latch is controlled by a first configuration data and the second latch is controlled by an inverted value of the first configuration data, wherein the particular wiring paths 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.
