THIS PAID FOR MY TRIP

Systems Engineering mit SysML6/9/20155

WHY Embedded with EA

Lot’s of new challenges ahead!

Functional Safety (ISO 26262,…)

UI Complexity

Multi and Many Core Hardware

Traceability

…….Systems Engineering mit SysML6/9/20156

WHY Embedded with EA

Inspiration:

Render requirement and hazard

information into the code

automatically!

Documentation = Product

WHY Embedded with EA - Sample

Systems Engineering mit SysML6/9/20158

Traceability from Requirement to Code

Round Trip/Reverse Engineering

Full (Behavior) Round Trip is myth

2015 forward only

Reverse for legacy

Optional: reverse for

method/function content

Systems Engineering mit SysML6/9/20159

New vs Legacy Project

Start today

Manage Risks

Integrate working/proven

code

Execution Semantics / Patterns

Many ways how to interpret Models in Code

Make sure you define it before you start

Many publications and vendors have their

interpretations

OMG has defined execution semantics for Activity

Diagram aka fUML

SCXML for State Charts by W3C

OMG currently started work to standardize State

Chart execution

Enterprise Architect out of the Box

Systems Engineering mit SysML6/9/201512

Enterprise Architect out of the Box

Systems Engineering mit SysML6/9/201513

Enterprise Architect out of the Box

Pro:

Only investment is Time

GDB and Visual Studio Support

Generate Code from Activities, Statecharts and Sequence

Diagrams

Executable UML available

Con:

Hard to maintain/debug

Advanced changes need call into Addin

With addin calls execution time is increasing

Not easy to certifySystems Engineering mit SysML6/9/201514

Enterprise Architect with Willert

Systems Engineering mit SysML6/9/201515

Enterprise Architect with Willert

Systems Engineering mit SysML6/9/201516

Enterprise Architect with Willert

Pro:

Turn Key Solution

Most IDE’s/Debugger/CPU’s supported

Generate Code from Activities, Statecharts

Easy to certify including Framework (at a cost)

Con:

Only feasible with a “new” Project

Tailored for Willert Framework

LieberLieber Embedded Engineer

Pro:

Lauterbach, PLS, I-System, GHS, Visual Studio Debuggers

Certification possible

Fast/Extensible code generation

Generation can be Debugged using familiar techniques

No Framework

Hardware Breakpoints

Con:

Need to know what you want

No Framework
