A.7.1 Tracing Variables

Sometimes it might be useful to know when a variable is set by the simulator or if a certain variable is used for calculation or not. To be able to observe access on certain variables, the trace statement can be used. The trace statement expects a list of variables, e.g.,

a = 1;
b = 2;
c = 3;
trace a, c;

trace reports each time a variable is

• used for calculation,
• overwritten by the simulator,
• deleted by the simulator.
