7. Performance Estimation Categories Time and accuracy trade off among different performance estimations 0 0.2s 3~4 hrs 15~18hrs Func. TLM Exec. Time (MP3)‏ Accuracy 100% 99% ~92% ~80% Board Timed TLM ISM PCAM TLM: Transaction Level Model ISM: Instruction Set Model PCAM: Pin/Cycle Accurate Model

8. Proposed Design Methodology

9. Timed TLM Generation

10. Timed TLM

12. Experiment Results · Error in TLM estimation is only 9% compared to 19% in ISM estimation · ISM cannot handle the design w/ custom HW components · Lines of code is ~ 12K · Annotation time is ~ 1 min · Perf. TLM can execute ~ 0.2 sec · CAModel can execute ~ 18 hour
