This panel, brought up by the Extract LR button in the Extract Menu, controls the interface to external inductance/resistance extraction programs described therein. The interface can also be controlled to a large extent with the !fh prompt line command.
The panel functionality is divided into three pages, selectable through the tabs along the top of the window. Common to all pages is a Help button, status line, and Dismiss button. The status line indicates the number of background extraction jobs currently running.
