Why do I get a CRITICAL WARNING about 'vfb_v1_0_2_viv_fifo_gen.v' when instantiating multiple MIPI CSI-2 Receiver Subsystems on my design?
[filemgmt 20-1741] File 'vfb_v1_0_2_viv_fifo_gen.v' is used by one or more modules, but with different contents, and may lead to unpredictable results.
Please reset and regenerate these modules to resolve the differences, or synthesize them independently
This is a known issue with the MIPI CSI-2 Receiver Subsystem that has been fixed in v2.0 (Rev. 1) in Vivado 2016.2 and later.
To work around this issue, you can synthesize each MIPI CSI-2 Receiver Subsystem using the Out of Context (OOC) flow.
This will synthesize each MIPI CSI-2 Receiver Subsystem separately and there will be no file name conflicts.
