Usage

Name Description
[-ref] Cell ref to rename

[-verbose] Suspend message limits during command execution

Description

Rename the reference name of a single non-primitive cell, or apply a reference prefix to all non-primitive cells in the current synthesized or implemented design.

This command provides a mechanism to change the non-primitive reference names in the current design so that they do not collide with the reference names in another design. This lets two modules or designs be synthesized or simulated together, while avoiding any name collisions between the two designs.

This command returns nothing when renaming the reference a single cell, and returns the number of cells renamed when used with -prefix_all. If the command fails, an error is returned.

Arguments

-ref <arg> - (Optional) Specify the current reference name of a non-primitive cell.

-to <arg> - (Optional) Change the reference name to the specified value.

-prefix_all <arg> - (Optional) Apply the specified prefix to the reference names of all non-primitive cells in the current design, except the top module.

-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 changes the specified reference name to the value indicated:

rename_ref -ref usbf_top -to MOD1_usbf_top

The following example applies the specified reference name prefix to all non-primitive cells in the current design:

rename_ref -prefix_all MOD1_
