frequency
An assignment with type frequency requires a value that is a frequency. A frequency
value consists of a numeric value and text representing units of frequency. The
numeric value can include a decimal point, and the numeric value and units of
frequency can be separated by a single space. For example, the following values are
legal:
■ “50.5 MHz”
■ 10kHz
Benefits of Command-Line Operation & Tcl Scripting Support
Each stage of the Quartus II software design flow corresponds to a command-line
executable file. Many of these executable files also support industry-standard Tcl
scripting for custom functionality or processing beyond the GUI design flow. The
Quartus II software offers the following scripting support benefits, also known as
CAR:
■ Custom Analysis
■ Automation
■ Reproducibility
Custom analysis allows you to build test procedures into the script and change design
processing based on the test results. Scripts can automate design flows to perform on
multiple computers simultaneously and easily archive and restore projects.
Reproducibility ensures that scripts use the same project setup and assignments for
every compilation, even when you transfer a project from one engineer to another. In
other words, you can use scripts as another level of design quality assurance.
