3. 05.12.2012 © FZI Forschungszentrum Informatik3 Context and Motivation SimCelerate: Modelica  FPGA compilation VHDL-based verification: slow System#-based verification: even slower

4. Objectives 05.12.2012 4 © FZI Research Center for Information Technology  Generate SystemC code from System# designs;  Develop and validate concepts for SystemC/System# Cosimulation and Interoperability. “the ability of two or more systems or components to exchange information and to use the information that has been exchanged” “the ability to link different simulations in order to make them communicate and interoperate”

5. SLDL’s Overview: SystemC vs. System# 05.12.2012 5 © FZI Research Center for Information Technology SystemCSystem# Written in C++Written in C# (.NET) Design and Simulation Framework Design, Simulation and Synthesis Framework (VHDL generation) Well-stablished: announced in 1999; large number of users and based software Recent: presented in 2012 by FZI Discrete-event Simulation model System Level Description Languages  Raise the abstraction level to the Electronic System Level (ESL)  Suitable for HW/SW co-design

6. Simulation Kernel 05.12.2012 6 © FZI Research Center for Information Technology SystemC  Cooperative multitasking (non-preemptive);  Deterministic (concept of Delta-Cycle) and Non-Deterministic features;  New SystemC standard (IEEE 1666-2011) presents new constructs to control the scheduler

7. 05.12.2012 © FZI Forschungszentrum Informatik7 Simulation Kernel System#  Similar to SystemC kernel;  Parallel Discrete-Event Simulator (PDES), but only Evaluation phase is parallelized;  Usage of new C# 5.0 features in Discrete-event simulation are currently being studied by FZI student David Hlavac.

8. Code Generation 05.12.2012 © FZI Forschungszentrum Informatik8  Language constructs/patterns identification and comparison;  Translation from System# to SystemC.

12. Current Status 12 05.12.2012 © FZI Research Center for Information Technology  Familiarization with SystemC and System#;  Study of Cosimulation state of art;  Some simple System# projects were successfully translated to SystemC; simulation results on both frameworks match together;  Difficulties with data type conversions;  Simple IPC and data transfer between C++ and C# achieved using Named Pipes.
