Vitis Model Composer generates a log file, model_composer.log, that is written to the Target or Export Directory specified on the Vitis Model Composer Hub block. This can help you diagnose issues related to code generation.

By default, Model Composer generates code for the model using a streaming micro-architecture in which blocks run concurrently via task pipelining, or dataflow. However, in some cases this streaming micro-architecture is not achievable, because the model includes an xmcImportFunction block that does not support streaming for example. In this case, Model Composer generates code in which the blocks operate sequentially. The Model Composer log file includes information to help you identify when this condition occurs, and possible causes.

The log file also contains information related to which blocks the Model Composer model uses.

If Export Type is set to IP Catalog, information related to running AMD Vitis™ HLS is provided. In these cases, you can find more detailed information in the vitis_hls.log file which can also be found in the directory specified in <Export Directory>/ip/<Subsystem Name>/src.
