Remove cells from the current design

Syntax

remove_cell [‑quiet] [‑verbose] <cells>...

Usage

Name Description
[-quiet] Ignore command errors
[-verbose] Suspend message limits during command execution
<cells> List of cells to remove

Categories

Netlist

Description

Remove cells from the current netlist in either an open Synthesized or Implemented design.

Note: You cannot remove cells from library macros, also called macro-primitives.
Netlist editing changes the in-memory view of the netlist in the current design. It does not change the files in the source fileset, or change the persistent design on the disk. Changes made to the netlist may be saved to a design checkpoint using the write_checkpoint command, or may be exported to a netlist file such as Verilog, VHDL, or EDIF, using the appropriate write_* command.
Note: Netlist editing is not allowed on the elaborated RTL design.

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.

<cells> - (Required) List of cells to remove. The instance name can be specified as a hierarchical name, from the top-level of the design. In this case, you must use the hierarchy separator character in the hierarchical instance name. You can determine the current hierarchy separator with the get_hierarchy_separator command.

Examples

The following example removes the fftEngine from the in-memory netlist of the current design:

remove_cell fftEngine
remove_cell usbEngine0/usb_out
