GR-290 10 - Generating stimulus with Waveform Editor Editing waveforms ModelSim SE User’s Manual You can edit waveforms interactively with menu commands, mouse actions, or by using the wave edit command (CR-400). To edit waveforms in the Wave window, follow these steps: 1 Create an editable pattern as described under "Creating waveforms from patterns" (GR- 289). 2 Enter editing mode by selecting View > Mouse Mode > Edit Mode or by clicking the Edit Mode icon. 3 Select an edge or a section of the waveform with your mouse. See "Selecting parts of the waveform" (GR-291) for more details. 4 Select a command from the Edit > Edit Wave menu or right-click on the waveform and select a command from the Edit Wave context menu. The table below summarizes the editing commands that are available. Operation Description Cut Cut the selected portion of the waveform to the clipboard Copy Copy the selected portion of the waveform to the clipboard Value Change the value of the selected portion of the waveform Delete Edge Delete the edge at the active cursor Insert Pulse Insert a pulse at the location of the active cursor Invert Invert the selected waveform section Mirror Mirror the selected waveform section Paste Paste the contents of the clipboard over the selected section or at the active cursor location Stretch Edge Move an edge forward/backward by "stretching" the waveform; see "Stretching and moving edges" (GR-292) for more information Move Edge Move an edge forward/backward without changing other edges; see "Stretching and moving edges" (GR-292) for more information Drive Type Change the drive type of the selected portion of the waveform Extend All Waves Extend all created waveforms by the specified amount or to the specified simulation time; ModelSim cannot undo this edit or any edits done prior to an extend command Undo Undo waveform edits (except changing drive type and extending all waves) Redo Redo previously undone waveform edits
Editing waveforms GR-291 These commands can also be accessed via toolbar buttons. See "Waveform editor toolbar" (GR-222) for more information. Selecting parts of the waveform There are several methods for selecting edges or sections of a waveform. The table and graphic below describe the various options. Action Method Select a waveform edge Click on or just to the right of the waveform edge Select a section of the waveform Click-and-drag the mouse pointer in the waveform pane Select a section of multiple waveforms Click-and-drag the mouse pointer while holding the key Extend/contract the selection size Drag a cursor in the cursor pane Extend/contract selection from edge-toedge Click these icons to extend/ contract selection from edge-to-edge Click Next Transition/Previous Transition icons after selecting section Drag cursor here to extend/ contract selection ModelSim SE User’s Manual
