Abstract
Disclosed is an integrated circuit (IC) layout method capable of reducing an IR drop as a result of an IC layout process. The method includes the following steps: performing the IC layout process and obtaining an original IC layout; performing an IR drop analysis on the original IC layout and identifying an IR drop hot zone; determining a circuit density limit of the IR drop hot zone; and performing the IC layout process again according to the circuit density limit and obtaining an updated IC layout.
