|---|---|
[-quiet]

Ignore command errors |
[-verbose]
|
Suspend message limits during command execution |
Description
Returns a list of all clocks that have been declared in the current design.
To get a list of specific clocks in the design, use the get_clocks command, or use the filter command to filter the results returned by all_clocks.
Clocks can be defined by using the create_clock or create_generated_clock commands.
Arguments
-quiet - (Optional) Execute the command quietly, returning no messages from the command. The command also returns TCL_OK regardless of any errors encountered during execution.
Note: Any errors encountered on the command-line, while launching the command, will be returned. Only errors occurring inside the command will be trapped.
-verbose - (Optional) Temporarily override any message limits and return all messages from this command.
Note: Message limits can be defined with the
set_msg_config command.Examples
The following example shows all clocks in the sample CPU netlist project:
% all_clocks
cpuClk wbClk usbClk phy_clk_pad_0_i phy_clk_pad_1_i fftClkThe following example applies the
set_propagated_clock command to all clocks, and also demonstrates how the returned list (all_clocks) can be passed to another command:
% set_propagated_clock [all_clocks]
