The C166 Compiler uses the Siemens Object Format (OMF-166) for object files. Complete symbol information is written to the generated object file. This allows any C16x/ST10 emulator to be used for program debugging.

The DEBUG directive embeds debugging information in the object file. When this directive is used, symbolic information, line numbers, and variable type information that allows type-specific display of variables and structures are included in the object file.
