Abstract
A method includes parsing a design of the integrated circuit to define cells in automatic power gating power domains, automatically creating an automatic power gating power domain netlist from the parsed design of the integrated circuit, and placing and routing the automatic power gating power domain netlist to produce a layout for the integrated circuit. The parsing partitions a high-level power domain of the integrated circuit into one or more automatic power gating power domains. The automatic power gating power domains have substantially zero-cycle power up times, thereby enabling transparent operation. Furthermore, the automatic power gating power domains may be automatically inserted into designs of integrated circuits, thereby relieving integrated circuit designers of the task of inserting power domains and associated hardware and software.
