DLATCH inferred as combinational loop on a specific condition

Warning (332125): Found combinational loop of 2 nodes File...

Warning (335091): The Timing Analyzer found 1 latches that cannot be analyzed as synchronous elements. For more details, run the Check Timing command in the Timing Analyzer or view the "User-Specified and Inferred Latches" table in the Synthesis report.

 

 

One of the condition the dlatch is not included as part of timing node for analysis, instead its treated as combinational loop

Can you provide the RTL code? It sounds like you've accidentally inferred one or more latches in your design, which should be avoided.
