Patent ID: 8161442

Claim:
A non-transitory machine readable medium containing executable computer program instructions which when executed by a data processing system cause the data processing system to perform a method of designing an integrated circuit (IC), the method comprising: creating a representation of a shielding mesh in a representation of a design of the IC, the shielding mesh comprising a first single layer shielding mesh and a first double layer shielding mesh which is coupled to the first single layer shielding mesh; creating a representation of a second shielding mesh having at least a first layer and having a first set of lines which are diagonally oriented relative to a second set of lines in the first single layer shielding mesh and are diagonally oriented relative to a third set of lines in the first double layer shielding mesh, wherein the second shielding mesh is inserted into an unshielded region of the first shielding mesh.
