Introduction to the SDC and TimeQuest
API Reference Manual
Introduction
The TimeQuest timing analyzer is a powerful ASIC-style timing analysis tool that
validates the timing performance of all logic in a design using industry standard
constraint, analysis, and reporting methodology.
The TimeQuest timing analyzer includes support for Synopsis Design Constraints
(SDC). Additionally, the TimeQuest timing analyzer includes an extensive tool
command language (Tcl) scripting API. This reference manual includes the supported
SDC constraints and commands, and the TimeQuest Tcl API commands.
This overview covers the TimeQuest timing analyzer support for scripted operation.
At the end of this overview is a table of additional documentation and resources.
What's Inside the SDC and TimeQuest API Reference Manual?
The Quartus II SDC and TimeQuest API Reference Manual is your reference guide to
TimeQuest timing analyzer constraints and commands, including command details,
usage, and examples.
All the information included in the Quartus II SDC and TimeQuest API Reference
Manual, as well as the most up-to-date list of commands, can also be found in the
Quartus II software Tcl API and command-line executable online help reference,
Qhelp. To access this information within Quartus II design software, type the
following command at the command prompt:
quartus_sh --qhelp

TimeQuest Timing Analyzer Scripting Support
The sdc and sta packages are supported in the quartus_sta command-line executable.
The sdc package contains the Synopsys Design Constraints (SDC) functions used to
specify constraints and exceptions to the TimeQuest timing analyzer.
The sta package contains the set of Tcl functions for obtaining advanced information
from the TimeQuest timing analyzer.
The quartus_sta command-line executable validates the timing performance of all
logic in a design using industry standard constraint, analysis, and reporting
methodology. You can use the TimeQuest analyzer's graphical user interface (GUI) or
command-line interface to constrain, run, and view results for all timing paths in your
design.
