--do_min_analysis[=on|off]

Option to perform a minimum timing analysis.

The Timing Analyzer performs only the following analyses:

■ clock hold

■ tsu

■ th

■ minimum tpd

■ minimum tco

--dump_atom_generated_clocks

Generate file with the clocks, generated by Timing Analyzer from ATOMs, in the TCL format.

--fast_model[=on|off]

Option to run Timing Analyzer (Fast Timing Model) using minimum delays. This option turns on the

"--do_min_analysis" option, which forces the Timing Analyzer to perform only the following analyses:

■ clock hold

■ tsu

■ th

■ minimum tpd

■ minimum tco

--fmax=<time unit>

Option to specify global fmax requirement.

--post_map

Option to run the Timing Analyzer (quartus_tan) based on the results from Analysis & Synthesis

(quartus_map).

The estimated timing delays are primitive results, which are not as accurate as the results obtained by

running the Timing Analyzer based on results from the Fitter (quartus_fit).

Example

quartus_map top

quartus_tan top --post_map

--speed=<device speed grade>

Option to specify the device speed grade for running Timing Analysis.

This option specifies the actual speed grade used by the delay annotator.
