UEISIM Desktop


Overview

The UEISIM is a Linux based system that runs Simulink models.

UEISIM Desktop allows remote monitoring and parameter tuning while a model is running.


Remote monitoring/Parameter tuning

• External mode:• Use Simulink itself as client to connect to the

UEISIM target.• UEISIM Desktop:

• A client written in C#, C/C++ or LabVIEW can display the model’s signals and parameters without Simulink being installed.

• Signals and parameters are also accessible via a web page.


Extra features (UEISIM desktop only)

• Remotely start/stop simulation• Host PC client can start or stop simulations

remotely• Timing statistics:

• Average simulation step execution time• Minimum step execution time• Maximum step execution time• Model execution time

Shared Data protocol


Shared data protocol• Implements a simple message based

protocol (set/get variable) using JSON or binary data representation

• Local processes communicate over UNIX sockets

• Remote processes communicate over TCP/IP sockets

• Web browser communicate over Web Sockets


Signal Monitoring • A model automatically publishes all “exported” signals

under the name:• /model_name/block_name/signal_name

• To export a signal, right-click and set “Storage Class” to “Exported Global”


Parameter tuning• A model also publishes all tunable parameters under

the name:• /model_name/block_name/param_name

• For example the constant block “value” parameter is tunable:


Data hierarchy

• This naming convention allows a hierarchical view of the model signals and parameters


Shared Data Client Shared Data client is an application that provides a

quick and easy way to monitor a model.


Client API

UEISIM Desktop API supports C/C++, .NET (C#, VB), LabVIEW and Javascript

The API provides the following services:• Start/Stop Simulation• Enumerate and read signals• Enumerate, read and write parameters• Reboot or shutdown UEISIM• Read timing statistics and CPU load


C# client API 1/4Create a client objectUeiSimTargetClient client = new UeiSimTargetClient();

Open communication with UEISIMclient.Open("192.168.100.2");

Load and Start Modelclient.LoadApp("/tmp/test_ai_rt2“, 2345);

if(client.IsAppRunning())

{

client.StopApp(); // Stop model if already running

}

client.StartApp();


C# client API 2/4Enumerate signalsfor(int sigIdx=0; sigIdx< client.GetNumSignals(); sigIdx++)

{

string sigName = client.GetSignalName(sigIdx);

double[] sigVals = client.GetSignalValue(sigIdx, client.GetSignalWidth(sigIdx));

Console.Write("{0} = {1}", sigName, sigVals);

}


C# client API 3/4Enumerate and tune parametersfor(int prmIdx=0; prmIdx=0<client.GetNumParams(); prmIdx=0 ++)

{

string prmName = client.GetParamName(prmIdx);

double[] prmVals = client.GetParamValue(prmIdx, client.GetParamWidth(prmIdx));

Console.Write("{0} = {1}", prmName, prmVals);

// Tune parameter

prmVals[0] = 102.90;

client.SetParamValue(prmIdx, prmVals);

}


C# client API 4/4Display timing statsConsole.WriteLine("Model ran for {0} secs", client.GetExecTime());

Console.WriteLine("Min TET = {0}", client.GetMinTET());

Console.WriteLine("Max TET = {0}", client.GetMaxTET());

Console.WriteLine("Avg TET = {0}", client.GetAvgTET());

Close communication channelclient.Close();


LabVIEW API 1/4

Open communication and start application


LabVIEW API 2/4

Enumerate and monitor signals values


LabVIEW API 3/4

Enumerate and tune parameters


LabVIEW API 4/4

Display timing stats


LabVIEW client example


HTML5 client • UEISIM Desktop web interface is built on top

of web sockets• Web sockets are part of HTML5. Supported in

the following browsers: Google Chrome Firefox Safari for MacOS and iOS Android web browser Internet Explorer 10


HTML5 client – default page


HTML5 client – custom page
