What's Good About PCB SI IOCell Editor in Model Editor? 16.5 Has a Few New Enhancements!

There are currently multiple options for model editing in the Allegro PCB SI environment. These include the legacy dialogs within the PCB SI and SigXplorer environments. Although these dialogs provide graphical editing, they are cascaded through many levels and default to text editing for certain model types. The goal is to provide a single environment for model editing and validation for all applications, and to replace Model Integrity and the legacy dialogs.

In 16.3, a new model editor application (ME) was introduced to provide users with more efficient tools to manage all models and libraries used. The general architecture and mainframe was provided to support various model formats. This included basic text editing functions, with some general operations on models, including validation with the golden parser. In upcoming releases, efforts will be made to provide a more convenient tool for graphical editing.

In the 16.5 release, Model Editor has been enhanced to include an IOCell Object Editor, which provides you an interface to edit and manage various parameters of the selected IOCell model.

Read on for more details …

The IOCell Object Editor provides you an interface to edit and manage various parameters of the selected IOCell model. You can edit any existing IOCell model that has been created and added to a library. You need to edit a model if you created it by cloning (copying) an existing model, so that it characterizes the device you are modeling. Also, if you create a model from scratch, it will contain default values that you may want to edit.

Opening Object Editor
To open Object Editor, right click on the model name in the Component View in ME and select Edit Object:

 
The IOCell Object Editor is displayed:

General Information
In the General Information page (shown above), you edit general attributes of the selected IOCell model.
