What's Good About ADW’s Pull-Down Lists? 16.6 Has a Few New Enhancements!

Comments(0)Filed under: Front-end PCB design, Library and design data management, PCB design, SPB, Allegro, Librarians, Allegro Design Workbench, property, Design Entry, Library flow, ADW, DBeditor, Library, design, design data management, selection filters, Grzenia, Allegro 16.6, 16.6, Cadence, Cadence Design Systems

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:
“YES/NO”
“COMPLIANT/NON-COMPLIANT”


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”:

 


Select “Close”.

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.

Jerry “GenPart” Grzenia
