History Window
This chapter describes the History window used for SISO plants. The
History window is used to display and manipulate the design history list,
which is a list of controllers that have been explicitly saved during the
design process. For a description of the History window used for MIMO
design, refer to Chapter 11, Introduction to MIMO Design.
Saving the Current Controller on the History List
You can save the current controller on the History list at any time, by
selecting the Add to History button in the Edit Menu of the ICDM Main
window, or pressing <Ctrl-A>
in the ICDM Main Window. You will be
prompted for a comment that is saved along with the design.
Opening the History Window
To make the History window appear, select Synthesis»History Window
in the ICDM Main window. This will close any open synthesis window,
automatically save the current controller on the history list if it has not
already been saved, and make the current controller the active or selected
design on the history list.
History Window Anatomy
The History window is shown in Figure 9-1.
From top to bottom, it consists of:
• A menu bar with Special, Edit, and Help menus.
• A scrolled list that shows the designs saved on the history list. Columns
show the history number, the date and time the controller was saved,
the type of controller, and a comment that was saved with the
controller. If the comments run off the visible part of the list,
you can scroll left and right, or resize the History
window wider.
