Signal Digital Segments
A digital segment in a Signal waveform can be:
Low (L), High (H), High-Z (Z), Don't care (X) or Data (D). After adding an empty Signal row, continue by adding individual segments to that waveform (see Signal & Bus Operations). Add a new digital segment to a Signal waveform Menu: Segment | Add Shortcut: a Each such segment contains two parts, transition and level, in this order. A label can be shown in the level part of each segment. D segments can be used in bi-directional signals, or in describing a protocol, where a bit could be either High or Low. Each segment part can be of width zero units, but not both. Thus, a segment is of a width of at least one unit. Digital segment options: - Level value selection (L, H, Z, X or D). - Segment width, transition and level parts, in units. - Segment value colors and fill style. You can customize the looks of D segments, but not L, H, Z or X to preserve their visual meaning. - Select to show or hide the segment's label with "Show label in level". - A set of label options include a choice of font, font color, font background color, and text alignment (horizontal and vertical) relative to the segment's level part. Special notes: * A transition between two back-to-back digital segments of the same type, except for two D types, is drawn as the Level part of the second segment, in order to create a smooth connection between the segments. * A transition between two back-to-back digital segments of different types, or two D types, is drawn as a smooth transition between the two segment levels. * To show a sloped transition from a D or X segment to another segment type, insert a Z segment between them. The Z segment should have non-zero transition width, and the level width should be of zero units. Initial values for - Value colors and fill, - Segment width, and - The set of segment label options, come from the Waveform options dialog (Diagram | Waveform options). If you check the "Use default options" box above a set of options, those options will be affected by any change made to them in the Waveform options dialog. This allows you to define the looks of multiple rows across the entire diagram. Otherwise, uncheck the box to individually customize each of those options. |
Superscript/Subscript
Signal name and segment label text can include superscript and subscript portions, e.g.: a""n"" t..RC.. Superscript text is surrounded by a pair of quotation marks, and subscript text is surrounded by a pair of dots. |
