quartus_map top --family=Stratix
quartus_fit top --part=EP1S10F780C7
# Run Timing Analysis for every speed grade
quartus_tan top --speed 5 --tao=top_5.tao
quartus_tan top --speed 6 --tao=top_6.tao
quartus_tan top --speed 7 --tao=top_7.tao
--tao[=<.tao file>]
Option to generate an ASCII Timing Analysis Output File (.tao). The .tao file contains results of the timing
analysis similar to results in the report file (.tan.rpt) but uses a different format.
This option can be used as a way to redirect the results of a given analysis.
Examples
quartus_tan top --tao=max_results
quartus_tan top --fast_model --tao=min_results
--tao_summary
Option to generate a Timing Analysis Summary File (.tao_summary). This file contains one line with the
worst-case fmax number, and can be used by external scripts to parse the fmax result easily.
The .tao_summary file has one line with the following format:
<revision_name>, <clock_name>, <fmax number> MHz
--tco=<time unit>
Option to specify global tco requirement.
--th=<time unit>
Option to specify global th requirement.
--timing_analysis_only
Option to skip delay annotation. This option can be used if you previously ran the Timing Analyzer
(quartus_tan) with delay annotation, or if the Fitter (quartus_fit) ran delay annotation as the final step.
If delay annotation has not been run for the requested timing model(s), then quartus_tan ignores this
option and performs delay annotation.
Some device families, such as Stratix
™
and Cyclone, may use delay annotation as part of a set of
post-fitting operations. When this occurs, the Fitter displays the following message:
Info: Started post-fitting delay annotation
In this case, you can save time by skipping delay annotation.
If --fast_model has been used before, or if the fitter optimized to meet Fast Model Timing, then this option
can be used together with --timing_analysis_only
