Hi @Anuj Singh, as of R2024b, there is no built-in option in coder.asap2.export to limit the A2L file generation to only top-level elements or to exclude 'SUB_GROUP's based on hierarchy depth. The function supports flags like 'IncludeAllRecordLayouts' and CustomOptions, but these do not provide control over the depth of SUB_GROUP nesting.
If your model includes Subsystem Reference blocks, the exporter will automatically generate SUB_GROUPs for parameters and signals defined within those referenced subsystems. This behavior cannot currently be disabled via export options.
Since you're already performing post-processing to remove subgroup entries at level 3 and beyond, that remains the most effective workaround. Some additional suggestions:
- You can script the post-processing of the .a2l file by parsing the file as text and removing or collapsing unwanted SUB_GROUP blocks.
- You can reduce A2L content at the source by setting the StorageClass to 'None' or configuring ExportToA2L = false for signals and parameters in nested subsystems. However, this requires more manual effort.
