Description
Assigns a constraint group to one of the following:
-
A net
-
A net group
-
The nets, routes, and terms in a set
-
A terminal
-
A fence or preferred direction region
You can optionally assign a constraint group to the non-taper routes of a net (-routes), or to all routes of a net (-all_routes).
Arguments
|
-all_routes
|
When used with -net or -set, the constraint group is also applied to all routes of the given net or nets in the set.
|
|
-area_boundary s_regionName
|
|
|
Specifies the name of a region to which the constraint group will be assigned. These regions are created by the create_soft_fence and create_preferred_direction_region commands.
|
|
-group s_groupName
|
Specifies the name of constraint group, or rule spec.
|
|
-instance s_instanceName
|
|
|
Used with -term to specify the name of the instance that the terminal belongs to.
|
|
-lib s_libName -cell s_cellName -view s_viewName
|
|
|
Used with -term to specify the library, cell and view that the terminal belongs to.
|
|
-net s_netName
|
Specifies the name of the net to assign the constraint group to.
|
|
-net_group s_netGroupName
|
|
|
Specifies the name of the net group to assign the constraint group to.
|
|
-routes
|
When used with -net or -set, the constraint group is also applied to the non-taper routes of the given net or nets in the set.
|
|
-set d_setObj
|
Specifies the set. All nets, routes and terms in the set will be assigned to the constraint group. All other objects in the set are ignored.
|
|
-term s_termName
|
Specifies the name of the terminal to assign the constraint group to. You must give the name of the instance (-instance) or the cellview (-lib, -cell, -view) that the terminal belongs to.
|
