The 16.6 Allegro Design Workbench (ADW) release now provides the ability to customize the pull-down list values for part property editing. Some classification properties require “freeform” values (tolerance, voltage, etc.) and other properties only accept certain values, for example:
This feature allows you to specify a set of allowable values for a property. The allowable values will appear in a pull-down list. This eliminates human error and promotes consistency and quality in the library.
Read on for more details…
In the ADW DBEditor, select File > Manage Part Classifications. For each property for which you'd like to enable pre-defined values, select the … field in the Pre-Defined Value column:
Select the “…” button next to an attribute (as an example, we’ll use the attribute – “ROHS”). ADW looks through the database for this Classification and retrieves all existing values. Add a new pull-down value, “NON-COMPLIANT”, by typing it into the text field and hitting enter:
Select the Save icon on the Toolbar. This will create a new rev of the classification. Because there are parts using that classification, it will bring up the following dialog:
Select “Preserve”. You will see a dialog showing that each part using that classification is being updated. Next you will be asked to enter a comment in the check-in log. Do so and select “Apply to All”:
You have just constructed a set of pull-down values that can be selected for the ROHS property in that classification… look at the “predefined” field of the ROHS property to confirm:
As an optional step you could mark the old Classification Obsolete so the Librarians don’t see both Classifications:
Open the ADW System Console and type lib_dist. If you don’t run lib_dist, then you will not be able to Obsolete the old classification because there are still parts linked to it:
Select Capacitors Fixed [1.0] and select Obsolete with the right mouse button. Select Yes when you see the following dialog:
Search for Capacitors Fixed. Sort Search results. Select CDN-CAP-0001 (as an example):
Checkout. Select Capacitors Fixed Classification. The ROHS Property should now have a Pulldown as shown below:
Select NON-COMPLIANT from the newly created pull-down list. Save, Check in. Add comment, select OK. Select Release and run lib_dist on the ADW System Console:
I’m looking forward to your feedback using this new capability.
