Abstract

A graphical representation for defining digital data and control signals is described. The tool disclosed uses OS/2* Presentation Manager* to aid in the visualization of the relationship between control signals and digital data. The graphical information is converted to digital data, clock select information and count values that may be used as inputs to digital systems. The resulting digital information is stored in a file which may be recalled at a later date and restored to graphical form for further additions, modifications, or deletions.

Graphical Utility to Define Digital Data and Control Signals

      A graphical representation for defining digital data and
control signals is described.  The tool disclosed uses OS/2*
Presentation Manager* to aid in the visualization of the relationship
between control signals and digital data.  The graphical information
is converted to digital data, clock select information and count
values that may be used as inputs to digital systems.  The resulting
digital information is stored in a file which may be recalled at a
later date and restored to graphical form for further additions,
modifications, or deletions.

      The main portion of this utility is the window pictured in Fig.
1.

      The icons along side of the main window represent different
tools used to define the output information.

      The top portion of the window, shown in Fig. 2, is used to
define the digital data.  Data is entered by defining one or more
fields in this section of the window.  Color is used to differentiate
between field types.  New fields are created by dragging and dropping
an icon from the data definition tool.  Field size is modified either
by dragging the icons or via a pop-up dialog box.  The dialog box
also provides the means to define a data pattern for the field.

      The next section of the window is the clock section (Fig. 3).
Control signal states are defined by the choice of clock signals and
the length of the rectangles created on the selected cl...
