Signal Routing, Triggering of State Machines
Hi,
i'm fairly new to OM and having some problems with a project i'm working on. My task is to model a simplifierd Computer/Software which gets command packets as an input and routes the right signals to the according triggers of state machines. My main problem with the model i've come up with is that it doesn't allow repated alteration between two states since i used when equations so i can trigger a transition only once. Is there a good possibility to reset the trigger variable immediately after the transition of the state machine? The only solution i've come up with is to set back the signal manually after a certain amount of time because otherwise i'm always having to much equations.
Here is a basic example of my code (Trigger Variables: outPortOn.Signal, outPortOff.Signal):
Code:
class Simulator
Console console;
PacketRouter packetrouter;
Buffer buffer;
equation
connect(console.outPort,packetrouter.inPort);
connect(packetrouter.outPortOn,buffer.inPortOn);
connect(packetrouter.outPortOff,buffer.inPortOff);
end Simulator;
connector Port
Boolean Signal;
end Port;
connector PacketPort
extends Port;
Integer Address;
end PacketPort;
class Console
PacketPort outPort;
equation
when time >= 8 then
outPort.Signal=true;
outPort.Address=0;
elsewhen time >= 6 then
outPort.Signal=true;
outPort.Address=1;
elsewhen time >= 4 then
outPort.Signal=true;
outPort.Address=0;
elsewhen time >= 2 then
outPort.Signal=true;
outPort.Address=1;
end when;
end Console;
class PacketRouter
PacketPort inPort;
Port outPortOn;
Port outPortOff;
equation
when inPort.Address==1 then
outPortOn.Signal=inPort.Signal;
end when;
when inPort.Address==0 then
outPortOff.Signal=inPort.Signal;
end when;
end PacketRouter;
class Buffer
Port inPortOn;
Port inPortOff;
Port outPortOn;
Port outPortOff;
equation
when sample(0,1) then
outPortOn.Signal=inPortOn.Signal;
outPortOff.Signal=inPortOff.Signal;
end when;
end Buffer;
Thank you
