The HDL code generated from the division operator in Stateflow’s Classic Action Language will not always be bit-true. The semantics of Stateflow division perform integer division. The chance of a mismatch is greater if the division is part of a larger expression, such as X = A - B/C. The generated HDL code will contain greater numeric precision than is retained by Stateflow.
To work around this issue, use the MATLAB Action Language in Stateflow.
