Select an item in the Wave window and then select Edit > Search to bring up the Wave Signal Search dialog box.
The Wave Signal Search dialog box includes these options:
You can locate values for the Signal Name(s) shown at the top of the dialog box. The search is based on these options:
Search Type: Any Transition Searches for any transition in the selected signal(s).
Search Type: Rising Edge Searches for rising edges in the selected signal(s).
Search Type: Falling Edge Searches for falling edges in the selected signal(s).
Search Type: Search for Signal Value Searches for the value specified in the Value field; the value should be formatted using VHDL or Verilog numbering conventions; see "Numbering conventions" .
Note: If your signal values are displayed in binary radix, see "Searching for binary signal values in the GUI" for details on how signal values are mapped between a binary radix and std_logic.
Search Type: Search for Expression Searches for the expression specified in the Expression field evaluating to a boolean true. Activates the Builder button so you can use "The GUI Expression Builder" if desired.
The expression can involve more than one signal but is limited to signals logged in the Wave window. Expressions can include constants, variables, and DO files. If no expression is specified, the search will give an error. See "Expression syntax" for more information.
Search Options: Match Count You can search for the n-th transition or the n-th match on value; Match Count indicates the number of transitions or matches to search for.
The Search Results are indicated at the bottom of the dialog box.
