Viewing XL Status

You can look up the XL Status information on the canvas by pointing over the object for which you want to look up the information.

To view the XL Status information on the canvas:

  1. Select the Options – Dynamic Display command.
    The Dynamic Display form appears.
  2. Select the Show Info Balloon check box.
  3. In the Setup tab, select the XL Status check box.
  4. Click OK.
    Pointing over a design object pops up the associated information balloon displaying the XL status information, as shown in the figure below.

The advantage of using the balloon information to view the XL Status is that you can get the required information straight on the canvas without having to pull up the Navigator assistant.

The XL Status information is displayed on the canvas only for instances, shapes, and pins. However, if a shape is attached to a net, the balloon also displays information about that net.

XL Status of a design provides up-to-date information about the XL-compliance of the design. The information, such as whether or not an instance is bound or has any opens or shorts, is dynamically updated and can be accessed via the Navigator assistant or through the information balloon available in the canvas.

You can also view the XL Status information in the Navigator assistant using one of the following:

The various XL Status values possible and their description is given below. Irrespective of the method you use to view XL Status, the same information is available for each object at a given point of time.

XL Status Value Description

shorts

layout nets with connectivity shorts markers

opens

layout nets with connectivity open markers including must-connect-pins

parameter difference

layout instance parameters different from the schematic counterpart

master difference

layout instance has a different master from the schematic counterpart

connectivity difference

layout instance connectivity different from the schematic counterpart

placed outside boundary

instance placed outside place and route boundary

complex binding limited check and no update

Instances are included in a complex binding between the schematic and layout. Limited information about these instances is reported and parameter values will not be updated automatically.

unbound

instance exists in layout but not bound to a layout instance

ungenerated

instance exists in schematic but not bound to a layout instance

ungenerated instance, no markers

net has no opens or shorts; therefore, no markers are generated; net is connected to an ungenerated instance

ungenerated instance, opens

net is connected to an ungenerated instance; net has opens

ungenerated instance, shorts

net is connected to an ungenerated instance; net has shorts

OK

object is XL-compliant

OK (ignore)

object is XL-compliant and has an ignore property set

OK (ignore for check)

object is XL-compliant and is ignored for check

(user binding)

instance bound manually using Define Device Correspondence

no markers

no discrepancies reported during last extraction run

Navigator — XL Status Column

The advantage of using the XL Status column in the Navigator assistant is that you get to view the XL status for all your design objects in one go. The column displays XL status information for each instance, pin, and net in the design and also cross-selects the object in the canvas.

The XL Status column is displayed in the Navigator assistant by default if the xlStatus environment variable is set to true.

You can use the Search feature to filter the information based on same status or sort the objects by XL Status by clicking the XL Status column header. This feature is extremely useful when resolving a particular type of design issue, such as resolving unbound instances. By default, the information in the Navigator assistant is sorted based on name.

You can also directly select an object from the Navigator and apply appropriate commands from the context menu to resolve the schematic and layout discrepancy being reported for the object in the XL Status column.

Navigator — Attention Icon

You can view the XL Status information by pointing towards the Attention icon ( ) displayed adjacent to the instance name. The icon is displayed only for those instances that have a design issue requiring your intervention.

Based on the type of the issue, you are required to take appropriate corrective action, after which the Attention icon disappears.

For example, an instance displaying an Attention icon may show the XL status in the information balloon as placed outside boundary (ignored). For the status to be converted to OK and the Attention icon to be removed, you must move the instance inside the PR Boundary.
