| main.cpp -- Main function for the dashboard controller for a |
| car. This controller contains a speedometer, two odometers (total |
| and partial distance), a clock, and the pulse generator. The |
| pulses are generated by the sensors placed around one of the wheel |
| shafts. The rate of pulse generation is determined by the speed of |
| the car, which is constant at 120 km/h. The clock represents the |
| real time. The signals in this program are traced. The simulation |
| is stopped by the odometers module. |
| |
| purpose -- no environment module; multiple modules at one level; |
| single processes within each module; input, output and clock |
| ports; internal and external signals; asynchronous function and |
| thread processes; one clock; tracing. |
