report_clocks
Usage
report_clocks [-append] [-desc] [-file <name>] [-panel_name <name>] [-stdout]
[-summary] [-waveform]
Options
-append: If output is sent to a file, this option appends the result to that file.
Otherwise, the file will be overwritten
-desc: Sort the clocks by name in descending order (ascending order is default)
-file <name>: Sends the results to an ASCII or HTML file. Depending on the extension
-panel_name <name>: Sends the results to the panel and specifies the name of the new
panel
-stdout: Send output to stdout, via messages. You only need to use this option if you
have selected another output format, such as a file, and would also like to receive
messages.
-summary: Create a single table with a summary of each clock
-waveform: Display the clocks graphically as waveforms
Description
Report can be directed to the Tcl console ("-stdout", default), a file ("-file"), the TimeQuest graphical
interface ("-panel_name"), or any combination of the three.
For the Tcl console, the clock details are reported in two sections. The first sections show all clocks, their
period, and their waveform. This includes generated clocks after an update_timing_netlist. The second
section shows details for all generated clocks. For the timing report, both sections are combined into a
single timing report.
