3.11. Interpretation of reset elements

1. For the purposes of this section, we define the “reset variable” to be the variable referenced by a reset element’s variable attribute, and the “test variable” to be the variable referenced by its test_variable attribute.

2. Each reset element describes a change to be applied to the reset variable when specified conditions are met during the simulation of the model.

3. All reset elements SHALL be considered sequentially for the equivalent variable set (see 3.10 Interpretation of map_variables elements) to which the reset variable belongs. The sequence SHALL be determined by the value of the reset element’s order attribute, lowest (least positive / most negative) having priority.

4. The condition under which a reset occurs SHALL be defined by the equality of evaluation of the test variable and the evaluation of the MathML expression encoded in the test_value.

5. When a reset occurs, the reset variable SHALL be set to the result of evaluating the MathML expression encoded in the reset_value.
