AWRout Web Page Header



AWRout is a SKILL & C++ based program that enables the Allegro/APD user to export a 3Di file. It is shipped as a context file, an executable and a menu and is installed in a way that loads the context/menu automatically each time Cadence Allegro or APD starts up.

AWRout Interface Flow

The AWROut User Interface inside of Allegro

After AWROut has been correctly installed, you will see a menu item across the top of the program window called AWROut. Clicking on this item will display several menu options.

AWRout's most important feature is the ability to extract a limited amount of data from large designs. There are two approaches here:

Geometric Windowing

The user can define a rectangular or polygonal window and only data inside the window will be extracted. However any component and its associated pads that cross the selection window will be extracted in their entirety.

Net Extraction

The user can define a net or nets and only conductors, pads and components associated with those nets will be extracted.

In order to support a proper analysis the user can also specify a "distance" and the area of the net will be expanded by the specified distance. This new "footprint" will be used as a template to extract and clip any conductors that lie inside of the footprint.

This behavior was designed to allow a user to collect nets and all nearby influencing metal without extracting the entire ground net.
