Selects the event markers that should be displayed in a viewer, and defines their display properties.

Prepare Markers

Polybench reference manual · Last updated 2026-06-18

This preparation operator tells a data viewer which event markers it should display, and what color and line thickness they should have. You can either specify exactly which event markers are to be shown, or specify that all event markers should be shown using the '*' wildcard character.

This is a special operator that does not perform any mathematical functions, but that only reads the signal channel configuration to be able to prepare certain properties for a signal viewer.

This operator should only be used if it is connected to a data viewer input, or to another viewer preparation operator.

For more information about this class of operators, see "Viewer Channel Configuration (Preparation operators) Overview".

General functionality

The behavior for displaying event markers (sometimes called 'annotations') in Y-T Viewers or the Marker Viewer ("Marker Viewer") is this: If no event markers are specified, the Y-T Viewers will show NO markers, and the Marker Viewer will show all markers in a default color. If the wildcard character '*' is used in the table, in stead of a normal event code, then Y-T Viewers and the Marker Viewer will show all event markers that have not otherwise been defined in the specified color.

Remember unconnected channels

type: True or False
Decides if settings from channels that are currently not connected should also be stored to disk.

Select one of those presets:
True or False
True may also be read like 'yes' and false like 'no'

During designing, channels may be added or removed at the input of this operator. All channels that were once connected are kept in memory, so that when you re-connect them, the settings are still available.
Normally, when you save your project to disk, those unconnected channel settings are not stored, because they may take unnecessary space.
However, sometimes your design may be so that different sets of known channels could be connected, in which case you want the settings to be available for all those channels. So, then Polybench should save the settings for the channels that are not connected as well. In that case, set this flag to True.

Caption

type: Word or phrase
