HEPSYCODE Modeling Methodology, Framework, and tools.
HEPSYCODE (HW/SW CO-DEsign of HEterogeneous Parallel dedicated SYstems) is a prototypal tool to improve the design time of embedded applications. It is based on a System-Level methodology for HW/SW Co-Design of Heterogeneous Parallel Dedicated Systems. The whole framework drives the designer from an Electronic System-Level (ESL) behavioral model, with related NF requirements, including real-time and mixed-criticality ones, to the final HW/SW implementation, considering specific HW technologies, scheduling policies and Inter-Process Communication (IPC) mechanisms. The system behavior modeling language introduced in HEPSYCODE, named HML (HEPSY Modeling Language), is based on the Communicating Sequential Processes (CSP) Model of Computation (MoC). It allows modeling the behavior of the system as a network of processes communicating through unidirectional synchronous channels. Through HML it is possible to specify the System Behavior Model (SBM), an executable model of the system behavior, a set of Non-Functional Constraints (NFC) and a set of Reference Inputs (RI) to be used for simulation-based activities. Through the execution of different steps, including a system-level Design Space Exploration (DSE) approach that allows the related co-design methodology to suggest an HW/SW partitioning of the application specification and a mapping of the partitioned entities onto an automatically defined heterogeneous multi-processor architecture, it is possible to proceed with system implementation.
HEPSYCODE uses Eclipse MDE technologies, SystemC custom simulator implementation, and an evolutionary genetic algorithm for partitioning activities, all integrated into an automatic framework that drive the designer from first input to final solution.
This repository contains the HEPSYCODE framework, which consists of a set of

To get started with HEPSYCODE, you can:
- Clone this repository to your local machine.
- Import the plugin projects in the HEPSYCODE-GUI directory in Eclipse.
- Use the HEPSYCODE Sirius-based tool to create and edit your HEPSYCODE models.
- Generate code from your HEPSYCODE models using the HEPSYCODE M2M XText transformation code.
- Simulate your HEPSYCODE models using the HEPSYCODE HEPSIM2 simulator. Examples are available in the HEPSYCODE-Workbench folder.

abstract = {Heterogeneous parallel devices are becoming increasingly common in the
embedded systems field. This is primarily due to their ability to improve
timing performance, while simultaneously reducing costs and energy.
In this context, this study addresses the role of a hardware/software (HW/SW)
co-simulation and analysis tool for embedded systems designed on heterogeneous
parallel architectures. In particular, it presents an extended System C-based
tool for functional and timing HW/SW co-simulation/analysis within a reference
Electronic System-Level HW/SW co-design flow. The description of the main features
of the tool, and the main design and integration issues represent the
core of the paper. Furthermore, the paper presents two case studies that
demonstrate the enhanced effectiveness and efficiency of the extended tool.
This is achieved through reduced simulation. Thanks to all this, the paper
contributes to fully motivate the industrial and research communities to
adopt and further investigate system-level approaches.}
