Abstract:
Reducing dynamic clock skew and/or slew in an electronic circuit is provided by: referencing a layout database and/or netlist of a design for the electronic circuit; identifying a set of neighboring buffer pairs with active buffers and adjacent sub-meshes, which are connected by a shorting bar; for each neighboring buffer pair of the set: placing a dummy buffer for each of their active buffers in the adjacent sub-meshes close to the active buffers; routing an input of a first dummy buffer located in a first sub-mesh to an output of an active buffer in a second sub-mesh; routing an input of a second dummy buffer located in the second sub-mesh to an output of an active buffer in the first sub-mesh; and connecting inputs of the first and second dummy buffers to the shorting bar.
