Syntax
set_propagated_clock [‑quiet] [‑verbose] <objects>Usage
| Name | Description |

[-quiet]

Ignore command errors |
[-verbose]
|
Suspend message limits during command execution |
<objects>
|
List of clocks, ports, or pins |
Description
Propagates clock latency throughout a clock network, resulting in more accurate skew and timing results throughout the clock network.
Note: This command operates silently and does not return direct feedback of its operation.
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.<objects> - (Required) A list of the clock objects to force propagation on.
Examples
This example specifies that the primary system clock from the top-level should be propagated:
set_propagated_clock [get_clocks top/clk]This example specifies that all clocks from "sublevel1" should be propagated:
set_propagated_clock [get_clocks sublevel1/*]
