Description
Reverts remastered vias to their original masters.
unclone_via reverts vias that were remastered in the current session. To use this command in a later session for remastered vias in the design, you must set the environment variable, db.save_original_via_master_property, to true prior to saving the design with the newly remastered vias, and again before opening the saved view. Setting this variable before saving the design causes the original via properties to be saved for each remastered via, and setting the variable before opening the saved design causes those properties to be loaded when the design is reopened.
setvar db.save_original_via_master_property true
You can optionally replace remastered vias with the via given by the lib, cell, and view arguments.
Arguments

When true, reverts all remastered vias to their original masters.
|
|
-expansion_distance f_userunit

|
-ignore_active_route_status [ true | false ]
|

(Optional) Specifies the library, cell and view of the replacement via.
This option replaces all vias in the specified set with the given via.
|
|
-max_vias_per_violation i_count
|

Specifies the maximum number of vias to revert for each processed Calibre violation if more than one remastered via overlaps the error bounding box. By default, only one via is processed per Calibre violation.
|
|
-rules {s_ruleName …}
|
Restricts processing of Calibre errors to the given rules. If not specified, all rules are processed.
|
|
-set d_setObj
|
Specifies the set that contains the remastered vias to revert.

-silent [ true | false ]
|
|
|
When true, outputs only essential messages. By default and when false, additional status messages are output.

|
-uncloned_set d_setObj
|
Puts all reverted vias into this set. Can be used only with the -violators argument.
|
|
-violators
|
Reverts any remastered vias that cause violations as reported by the checker or a Calibre error file. You must run the check commands and/or load the Calibre files prior to using this command.
