The Test Pattern Generator MegaCore function can be used to produce a video stream
compliant with the Avalon-ST Video protocol that feeds a video system during its
design cycle. The Test Pattern Generator MegaCore function produces data on request
and consequently permits easier debugging of a video data path without the risks of
overflow or misconfiguration associated with the use of the Clocked Video Input
MegaCore function or of a custom component using a genuine video input.
The Test Pattern Generator MegaCore function can generate either a uniform image
using a constant color specified by the user at compile time or a set of predefined color
bars. Both patterns are delimited by a black rectangular border. The color bar pattern
