End a set of commands that can be undone/redone as a group
endgroup [‑quiet] [‑verbose]
|Ignore command errors
|Suspend message limits during command execution
Ends a sequence of commands that can be undone or redone as a series. Use
startgroup to start the sequence of commands.
You can have multiple command groups to
redo, but you cannot nest command groups. You must use
endgroup to end a command sequence before using
startgroup to create a new command sequence.
startgroup/endgroup commands are provided to support sequences of related commands that can be undone via the
undo command, or redone if needed using the
redo command. However, some Tcl commands can trigger an
endgroup unexpectedly, and certain commands do not support either
REDO. The limitations are not fully defined.
-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.
-verbose - (Optional) Temporarily override any message limits and return all messages from this command.
startgroup, executes a sequence of related commands, and then executes the
endgroup. This sequence of commands can be undone as a group:
add_cells_to_pblock pblock_wbArbEngine \
[get_cells [list wbArbEngine]] -clear_locs
add_cells_to_pblock pblock_usbEng \
[get_cells [list usbEngine1/usbEngineSRAM]] -clear_locs
