MIPI CSI-2 Receiver Subsystem v2.0 (Rev. 1) - Why do I see timing failing on the video_aresetn when using two CSI-2 Receiver Subsystems with one as a master and one as a slave?

描述

Why do I see timing failures on the video_aresetn when using two CSI-2 Receiver Subsystems, with one as a master and one as a slave?

解决方案

You can work around this issue by adding the following constraints using the SCOPED_TO constraint that points to the CSI-2 Receiver Subsystem.

set_false_path -to [get_pins -hier *_reg*/CLR]
set_false_path -to [get_pins -hier *term_reg*/PRE]

This issue will be resolved in the CSI-2 Receiver Subsystem v2.1 in Vivado 2016.3.
