The Test Pattern Generator IP cores generate a video stream that displays either color bars for use as a test
pattern or a constant color for use as a uniform background. You can use these IP cores during the design
cycle to validate a video system without the possible throughput issues associated with a real video input.
IP Cores Feature
Test Pattern Generator
• Produces a video stream that feeds a video system during
its design cycle.
• Compliant with the Avalon-ST Video protocol.
• 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 IP core or of a custom
component using a genuine video input.
• Supports 1 pixel per cycle.
Test Pattern Generator II
• Produces a video stream that feeds a video system during
its design cycle.
• Compliant with the Avalon-ST Video protocol.
• 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 IP core or of a custom
component using a genuine video input.
• Supports up to 4 pixels per cycle.
Test Pattern
The Test Pattern Generator IP core 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 is a still image composed
with a set of eight vertical color bars of 75% intensity (white, yellow, cyan, green, magenta, red, blue,
black).
