Issue with MIPI CSI2 Encrypted IP File During Project Integration

Without the .qar project to reproduce the issue, it is difficult to determine the exact root cause.

Based on the reported error, the most likely cause is that the merged project is changing the Verilog compiler directive environment seen by the generated MIPI CSI2 encrypted files.
 

The key message is:

net type must be explicitly specified for 'in_clk' when default_nettype is none
 

This usually indicates that a file compiled earlier in the project has enabled default_nettype none, and that setting remains active when the MIPI-generated file is compiled.

A possible workaround is to limit default_nettype none usage to user RTL only, and restore default_nettype wire before the MIPI CSI2 IP files are compiled.
