Fully-automated synthesis of power management controllers from UPF

We present a methodology for automatic synthesis of power management controllers for System-on-Chip designs by using an extended version of the Unified Power Format (UPF). Our methodology takes an SoC design and a UPF-based power design, and automatically generates a power management controller in Verilog/VHDL that implements the power state machine specified in UPF. It performs a priority-based scheduling for all power state machine actions, connects each power management signal to the corresponding logic wire in the UPF design and integrates the controller into the System-on-Chip using a configurable bus interface. We implemented the proposed approach as a plugin for Synopsys Design Compiler to close the gap in today's power management flows and evaluated it by a RISC-V System-on-Chip.
