UM-250 9 - Waveform analysis Saving zoom range and scroll position with bookmarks ModelSim SE User’s Manual Bookmarks save a particular zoom range and scroll position. This lets you return easily to a specific view later. You save the bookmark with a name and then access the named bookmark from the Bookmark menu. Bookmarks are saved in the Wave format file (see "Adding objects with a window format file" (UM-244)) and are restored when the format file is read. Managing bookmarks The table below summarizes actions you can take with bookmarks. Action Menu Command Add bookmark Edit > Insert Bookmark bookmark add wave (CR-71) View bookmark View > Bookmark > bookmark goto wave (CR-73) Delete bookmark Tools > Bookmarks bookmark delete wave (CR-72) Adding bookmarks To add a bookmark, follow these steps: 1 Zoom the wave window as you see fit using one of the techniques discussed in "Zooming the Wave window display" (UM-249). 2 Select Edit > Insert Bookmark. 3 Give the bookmark a name and click OK. Editing Bookmarks Once a bookmark exists, you can change its properties by selecting Tools > Bookmarks. See "Modify Breakpoints dialog" (GR-249) for more details.
Searching in the Wave and List windows Finding signal names Searching in the Wave and List windows UM-251 The Wave and List windows provide two methods for locating objects: Finding signal names – Select Edit > Find or use the find command (CR-176) to search for the name of a signal. Search for values or transitions – Select Edit > Search or use the search command (CR- 260) to locate transitions or signal values. The search feature is not available in all versions of ModelSim. The Find command is used primarily to locate a signal name in the Wave or List window. When you select Edit > Find, the Find dialog appears: The Find dialog gives various options that are discussed further under "Find in .wave dialog" (GR-233). One option of note is the "Exact" checkbox. Check Exact if you only want to find objects that match your search exactly. For example, searching for "clk" without Exact will find /top/clk and clk1. There are two differences between the Wave and List windows as it relates to the Find feature: In the Wave window you can specify a value to search for in the values pane. The find operation works only within the active pane in the Wave window. ModelSim SE User’s Manual
