chuanma / stslib Goto Github PK

I wanted an easier way to build the application, so I added a toplevel makefile and changed the others a bit

Consider the STS model and specifications below. It consists of a car window control. The motor can move up and down, and the system has two sensors. The sensors can be On(Aan) and Off(Uit).

The motor may only start to move up (down) when the maximally down (up) sensor is on. The motor may only stop if the motor is moving down (up) and the maximally down (up) sensor is on.

The generated state-space contains a deadlock location:
Both sensors are On (Aan) and the motor is Stopped. This location is not marked. There are no outgoing transitions.

STS-file:

root = CarWin_Simple
{
CarWin_Simple = AND {Motor, UpSensor, DownSensor}
Motor = OR {Stopped, MovingDown, MovingUp}
UpSensor = OR {Off, On}
DownSensor = OR {Uit, Aan}
}

Motor
{motorStop, motorMoveUp, motorMoveDown}
{upSOn, downSOff, upSOff, downSOn}
{
[Stopped motorMoveDown MovingDown]
[Stopped motorMoveUp MovingUp]
[MovingDown downSOn MovingDown]
[MovingDown motorMoveUp MovingUp]
[MovingDown motorStop Stopped]
[MovingDown upSOff MovingDown]
[MovingUp downSOff MovingUp]
[MovingUp motorMoveDown MovingDown]
[MovingUp motorStop Stopped]
[MovingUp upSOn MovingUp]
}

UpSensor
{}
{upSOn, upSOff}
{
[Off upSOn On]
[On upSOff Off]
}

DownSensor
{}
{downSOff, downSOn}
{
[Uit downSOn Aan]
[Aan downSOff Uit]
}

{Stopped, Off, Aan}
{{Stopped, Off, Uit}}
{}

SPEC file:
