This paper presents a Platform-based SoChardware/software co-design environment namedHSCDE. It introduces the overall structure of HSCDE,describes the Platform-based SoC system modelingtechnology, ant algorithm based hardware/softwarepartitioning technology and Hierarchical DirectedAcyclic Graph based performanceconstraintassignmenttechnology. HSCDE supports Platform-based SoC hardware/software co-design *** supports almost all the design phases from SoCsystem modeling to RTL level SoC system. It dividesSoC hardware/software co-design into system modelinglevel (level 1), virtual components level (level 2) andreal components level (level 3), and it performs the 2mappings among the 3 design levels by DesignPlanning (mapping 1) and Virtual-Real Synthesis(mapping 2). We have clone SoC system design for MP3player SoC, MEPG2 player SoC and CDMA wirelesscommunication SoC in HSCDE environment. Resultsshow that HSCDE effectively supports Platform-basedSoC hardware/software co-design methodology;itenhanced system reuse of existing SoC design. Statisticsindicate an average of 10％～25％ revisions on platformtemplates for a new SoC design, and we achievedplatform template reuse ratio by 75％～90％.
