$vcdplusevent

The $vcdplusevent task allows the user to record a unique event

for a signal at the current simulation time unit. These events can be

displayed in the Waveform Window, Logic Browser, and Register

Window.

There can be a maximum of 244 unique events, plus the pre-defined

"glitch" event which is automatically generated by the pli, and a "Too

many events" event which all unique events beyond the allowed 244

will be automatically named.

Syntax:

$vcdplusevent (<signal>, "<event_name>",

"<severity><shape>");

where

signal is any valid signal name.

event_name is a unique string which describes the event. This

event_name will appear in the status bar of the Waveform Window,

Logic Browser, or Register Window when the mouse is placed on the

event marker.

severity is a single character with legal values E, W, or I, which

indicates the severity of the event. The severity of the event may be

Error, Warning, or Information respectively. Colors associated with

the severity level are set in the X Resource file or NT registry. The

defaults are Red=Error, Yellow=Warning, and Green=Information. If

the severity is not interpretable, it will default to E.

shape is a single character with legal values S, T, or D which indicates

the geometry of the event as drawn by Virsim, and are Square,

Triangle, and Diamond respectively. If the geometry is not

interpretable, it will default to T.
