Customizing Pin Cross-References

You can customize environment variables for pin cross-references as follows:

■Pin reference format

The pinRefFormat environment variable specifies the format for displaying the pin reference information that appears next to each pin when you use Sheet – Cross

Reference.

■Pin reference duplicates

The pinRefDuplicates environment variable specifies whether the editor reports duplicate pin references within the same zone of a multisheet schematic when you use

Sheet – Cross Reference.

■Pin reference sorting

The pinRefSorting environment variable specifies how the editor sorts pin references when you use Sheet – Cross Reference.

Presetting the Title Block Values

The Schematic Title Block Properties form, available when you choose Sheet – Edit from a schematic design having a title block, can be preset with values if the properties already exist on the title instance. The title form is dynamic and created every time you want to see the title information. The values in the form are taken from the properties of the title instance.

You can preset the values by adding CDF properties to the title cell and saving the defaults.

The properties exist on the instance and will be presented on the form.

To add CDF properties, do the following:

1.From the CIW, choose Tools – CDF – Edit. The Edit Component CDF form appears.

2.Set CDF Selection to Cell.

3.Set CDF Type to Base.

4.Set Library Name to US_8ths.

Note: You need to have write permission to edit this library.

5.Set Cell Name to Title.
