CLOCKTREE TUNING SHIMS AND SHIM TUNING METHOD

摘要

A digital storage medium stopng electronic data for use with a clock tree design tool to design a clock distribution network (12) wit an integrated circuit (10), the electronic data implementing a library of shim cells, wherein each of the shim cells in the library represents a physical embodiment of a different clock dpver cell of a plurality of clock driver cells (20) and wherein all of the shim c in the library are interchangeable in the clock distribution network design without requiring any change in placement or routing with the integrated circuit to maintain compliance with design requirements for the integrated circuit (10)
