Abstract:
1. 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: searching, within a representation of the IC, a shielding mesh of the IC representation for at least one first signal line determining that the at least first signal line routed through the shielding mesh comprising a first set of reference voltage lines and a second set of reference voltage lines does not require shielding; determining that at least one second signal line should be shielded; moving the at least one first signal line to a location outside the shielding mesh if the at least one first signal line does not require shielding; and placing the at least one second signal line into the shielding mesh of the IC representation.
