DESIGN METHOD FOR MULTI-POWER SOURCE INTEGRATED CIRCUIT, DESIGN SUPPORT SYSTEM FOR MULTI-POWER SOURCE INTEGRATED CIRCUIT AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a method and system for acquiring a circuit in which at least two items of delay, power consumption and area are optimized by taking into consideration a plurality of power supply voltages during designing functions.;SOLUTION: The design support system of a multi-power source integrated circuit executes the performance analysis of delay or the like (step A4), and when any constraint is not satisfied, a floor plan and performance analysis result are input, and a voltage island is generated (step A6). Then, constraints (delay constraints, power consumption constraints, area constraints, and voltage island-related constraints of chip and each module) for the next operation composition are extracted from the floor plan, performance analytic result and voltage island (step A7), and re-executed from the operation composition (steps A2 and so on), and the optimal solution is searched.;COPYRIGHT: (C)2008,JPO&INPIT
