One of the first steps in learning how to program is reading and tracing existing code. In order to avoid the error-prone task of generating variations of a tracing exercise, our tool TATSU generates instances of a given code skeleton automatically. This is achieved by a finite unwinding of the program in the style of bounded model checking and using the SMT solver Z3 to find models for this unwinded program.* We would like to thank Stefan Podlipnig for his continuing support and input on the paper. His lead in the introductory programming course for computer science on TU Wien with his ideas for TATSU made this work possible. We would also like to thank Nikolaj Bjørner for his help with integrating Z3 in TATSU.1 https://git.logic.at/ep1-tools/tatsu-generator
