Example: Breakfast - a modeling tool <strong>for</strong> <strong>System</strong>C<br />
Easy to create virtual plat<strong>for</strong>m model<br />
Using QEMU <strong>for</strong> CPU models<br />
Easy to connect QEMU to <strong>System</strong>C models<br />
Easy to connect interrupt signals to CPU<br />
No need of deep knowledge about <strong>System</strong>C TLM2.0<br />
Abstraction is LT(Loosely Timed)<br />
Easy to create <strong>System</strong>C code <strong>for</strong> high-level synthesis<br />
Pin level interface between modules is generated automatically<br />
<strong>System</strong>C code <strong>for</strong> line buffer <strong>for</strong> image processing is generated<br />
Designers can concentrate coding <strong>for</strong> algorithm<br />
<strong>System</strong>C model <strong>for</strong> high-level synthesis can be used on a virtual plat<strong>for</strong>m<br />
No clock on a virtual plat<strong>for</strong>m<br />
Virtual plat<strong>for</strong>m uses the same <strong>System</strong>C code <strong>for</strong> a register I/F(address<br />
decoder) as high-level synthesis

Experiences from practice<br />
"5-fold productivity increase when<br />
compared to standard development<br />
methods"<br />
"The quality of the generated code is<br />
clearly better, simply because the<br />
modeling language rules out errors"<br />
"An increase of at least 750% in<br />
productivity, and greatly improved<br />
quality in the code and development<br />
process"

Preschern, C., et al 2012
<strong>Modeling</strong> both SW and system<br />
Combining two or<br />
more languages via<br />
metamodeling<br />
Metamodel covers<br />
integration rules <strong>for</strong><br />
– Correctness<br />
– Consistency<br />
– Completeness
Hardware and software co-design<br />
Integrating various views with a common metamodel<br />
– e.g Y-model<br />
Main challenge<br />
is organizational<br />
– Changes<br />
status quo
Design space exploration<br />
Per<strong>for</strong>mance analysis, error analysis, fault tolerance etc.<br />
– Integrate with tools like ABSOLUT, SPIN, UPPAAL, etc.<br />
– Annotate results back to models
Automating testing<br />
<strong>Modeling</strong> test cases/test logic and generating test data
