From simulation to automatic code generation for embedded

targets

10

E4Coder - facts

is a toolset available since 2012 which is able to:• simulate continuous time and discrete time designs• simulate finite state machines• GUI panel generation• generate code without changing the design• with and without RTOS

• Bare Metal / ERIKA Enterprise / Linux / RTAI / Windows

• support for multi-rate designs

E4Coder success stories

example of success stories using E4Coder:

• HVAC Boiler display application

• 54 states (including 2 AND and 17 OR superstates)

• 9 levels deep

• 8 bit microcontroller

• 6184 bytes of flash, 547 bytes of RAM.

12

…and finally on the real target!

13

E4Coder success stories

Velometro used E4Coder for the VeloCar control model

• both in simulation and code generation

• same diagram for different target boards

• press release available

… but… what is a VeloCar?

15

building blocks

• E4Coder Code Generator• code generation for embedded targets

• SMCube• simulation/codegen of Finite State Machines

• E4Coder GUI• simulation/codegen of GUI Panels

• E4Box• all-in-one embedded computing box

16

E4Coder CG

• optimized code generation for embedded devices

• peripheral blockset• simulation ports• independent from the target

• mapping done at code generation

• same diagram used for simulation and code generation

• multithread code generation support

• software architecture generation (tasks, …)

17

SMCube

• stands for: SMCube is a State Machine System Modeler

• Flat and Parallel Discrete-time State Machine editor

• simulation and code generation of state machine diagrams

• integrated in Scilab

18

E4Coder GUI - customizable UI designer

E4Code GUI is a simple customizable UI designer:

• design simple user interfaces

• insert simple widgets

• simulate the interface

• generate QT target code

Ports

Edit area

Properties Widgets

19

E4Box

E4Box is a ready to use all-in-one embedded computing box

• Intel Atom processor

• NI PCI-6221 Data acquisition board

• Open Edition• Linux+RTAI+Comedi+open source code generator

• Professional Edition• Open Edition + E4Coder

20

dashboard demo

the Dashboard example is available as one of the default E4Coder demos.

the demo includes:• two state machines that control gear change logic• an E4CoderGUI simulation panel that shows an animated

motorbike dashboard.

The demo mimics the Matlab/Simulink/Stateflow demo named“Modeling an Automatic Transmission Controller”http://www.mathworks.it/products/simulink/examples.html?file=/products/demos/shipping/simulink/sldemo_autotrans.html

21

today, Scilab 5.5.2, 32/64bit, Windows

availability on Scilab – Today!

22

licensing

• the E4Coder toolbox for Scilab is available under a commercial license

• flexible licensing available, per seat rental,node locked or floating

23

roadmap

current support for Scilab 5.5.2 includes simulation-only support.

future versions will include:

• porting on Linux machines

• support for code generation

• improvements on SMCube• better simulation interface• history state

• additional target boards

• multi-panel GUI

• French language translation
