rename - rename object in the design

yosys> help rename

rename old_name new_name

Rename the specified object. Note that selection patterns are not supported
by this command.

rename -output old_name new_name

Like above, but also make the wire an output. This will fail if the object is
not a wire.

rename -src [selection]

Assign names auto-generated from the src attribute to all selected wires and
cells with private names.

rename -wire [selection] [-suffix <suffix>]

Assign auto-generated names based on the wires they drive to all selected
cells with private names. Ignores cells driving privatly named wires.
By default, the cell is named after the wire with the cell type as suffix.
The -suffix option can be used to set the suffix to the given string instead.

rename -enumerate [-pattern <pattern>] [selection]

Assign short auto-generated names to all selected wires and cells with private
names. The -pattern option can be used to set the pattern for the new names.
The character % in the pattern is replaced with a integer number. The default
pattern is '_%_'.

rename -witness

Assigns auto-generated names to all $any*/$all* output wires and containing
cells that do not have a public name. This ensures that, during formal
verification, a solver-found trace can be fully specified using a public
hierarchical names.

rename -hide [selection]

Assign private names (the ones with $-prefix) to all selected wires and cells
with public names. This ignores all selected ports.

rename -top new_name

Rename top module.

rename -scramble-name [-seed <seed>] [selection]

Assign randomly-generated names to all selected wires and cells. The seed option
can be used to change the random number generator seed from the default, but it
must be non-zero.
