Conclusion: The 2021 Workflow in Practice

target_library:

The physical library containing standard cells for mapping (e.g., tcbn65lp.db ). Use the provided DC shell script templates as

report_power > reports/power.rpt

set_fix_multiple_port_nets -all -buffer_constants

1. Use the provided DC shell script templates as starting points; adapt read_lib, set_operating_conditions, and create_clock entries to your target flow.
2. Run iterative compile -> report_timing -> report_power -> examine reports and apply constraint refinements rather than attempting one-shot perfect constraints.
3. Add explicit false-path and multi-cycle-path constraints early to prevent wasted optimizations.
4. Use compile_ultra and area/power directives selectively and compare reports after each major change.
5. Back-annotate with SDF and run gate-level timing sims after synthesis changes; keep a small regression set for fast checks.
