Overview
This workshop shows you how to maximize your productivity when using PrimeTime. You will validate and enhance run scripts, quickly identify and debug your design violations by generating and interpreting timing reports, remove pessimism with path-based analysis, and generate ECO fixing guidance to downstream tools.
Topics include:
- Preparing for STA on your design, including investigating and analyzing the clocks that dictate STA results
- Validating inherited PrimeTime run scripts
- Leveraging the latest PrimeTime best practices to create new run scripts
- Identifying opportunities to improve run time
- Performing static timing analysis
- Providing ECO fixing guidance to downstream tools
Objectives
At the end of this workshop the student should be able to:
- Interpret the essential details in a timing report for setup and hold, recovery and removal, and clock-gating setup and hold
- Generate timing reports for specific paths and with specific details
- Generate summary reports of the design violations organized by clock, slack, or by timing check
- Validate, confirm, debug, enhance, and execute a PrimeTime run script
- Create a PrimeTime run script based on seed scripts from the RMgen utility
- Identify opportunities to improve run time
- Create a saved session and subsequently restore the saved session
- Identify the clocks, where they are defined, and which ones interact on an unfamiliar design
- Reduce pessimism using path-based analysis
- Use both a broad automatic flow for fixing setup and hold violations and a manual flow for tackling individual problem paths.
Audience Profile
Design or verification engineers who perform STA using PrimeTime.
