|---|---|---|---|
| Complete analoguemeasured · The node the temperature is written from has a capacitor on it, a resistor to a node a DC source holds fixed, and a third element feeding it. The resistor times the capacitor has to be under a day, so a leak nobody meant does not count as the loss. | ✓ pass | ✓ pass | ✓ pass |
| Real hysteresismeasured · Re-run, once in band the heater switches on low and off high, at least 1 °C apart and at least 2 s per cycle, and the netlist has a switch that remembers: a SW model with a hysteresis voltage, or a source that reads its own output. A single-threshold switch sits at the set point with a swing near zero. | ✓ pass | ✓ pass | ✓ pass |
| Starts coldmeasured · Initial condition at ambient, and the transient run with uic so it is honoured. | ✓ pass | ✓ pass | ✓ pass |
| Holds 92–96 °Cmeasured · The written temperature re-read: once in band it never leaves it. | ✓ pass | ✓ pass | ✓ pass |
| Writes the .txtmeasured · A wrdata line in .control, and the file actually appears. | ✓ pass | ✓ pass | ✓ pass |
Ground truth: The netlist itself: re-run in ngspice offline, and the temperature it writes out read back. A thermostat with a dead band is a stateful thing, so a bare comparator on one threshold is wrong however plausible the plot looks. Every model on this task.
