Performing Static Timing Analysis

Run the

quartus_sta interactive Tcl shell independently and

execute Tcl commands and scripts at the Tcl prompt.

Using Classic Timing Analyzer

You can run the timing analysis independent of the compile process in

one of two ways:

Use the

execute_module -tool tan Tcl command to run a

timing analysis Tcl script in

quartus_tan from within the basic

quartus shell,

quartus_sh.

Run the

quartus_tan interactive Tcl shell independently and

execute Tcl commands and scripts at the Tcl prompt.

For more information on running static timing analysis in the Quartus II

software, refer to the Timing Analysis section in the Quartus II Handbook.

For Tcl commands related to static timing analysis, refer to the Timing

section of the Tcl Packages and Commands in the Quartus II Scripting

Reference Manual.

Static Timing Analysis in Primetime

The Quartus II software can also generate files required to run STA in

Synopsys’ PrimeTime. The following example Tcl commands direct the

Quartus II software to generate PrimeTime files for STA.

## Tcl Script to Generate PrimeTime STA File Output

execute_module -tool sta -args --tq2pt

execute_module -tool eda -args "--tool primetime --format verilog --timing_analysis"

The files generated by the Quartus II software are organized in a

subdirectory within the project directory. For example, after compiling a

Stratix II prototype design (

demo_design), the following verilog (.vo)

SDF (.sdo) and PrimeTime Tcl script (.tcl) are created in the project

directory.

timing\

primetime\

demo_design_v.sdo

demo_design.pt.tcl

demo_design.collections.sdc

demo_design.constraints.sdc

The Tcl script includes all timing constraints applied during the

Quartus II software compilation.
