CodeSimulink: Automatic synthesis of analog circuits

A tool (CodeSimulink) is being developed, based on Simulink, for three different purposes:

  • automatic synthesis of analogic circuits (at board level) from high level Simulink specifications. This allows true mixed-signal HW/SW cosimulation and codesign of embedded systems.
  • automatic synthesis of asynchronous circuits (FPGAs and ASICs) from high level Simulink specifications. This allows true HW/SW cosimulation and codesign of asynchronous and mixed-asynchronous systems.
  • automatic synthesis of truly data-flow HW/SW embedded systems, both data- and control-dominated (CPUs, soft and hard cores, FPGAs and ASICs) from high level Simulink specifications. This allows true cosimulation and codesign of HW/SW systems, keeping into account the different paradigms of CPUs (intrinsically data-flow) and FPGAs (intrinsically register-transfer).

The tool extends another tool previously developed by the group, which aimed at a straightforward and pervasive application of HW/SW codesign methodologies also to non-expert personnel. So far the design framework has been developed and tested and a set of libraries is currently under development.

The CodeSimulink tool is currently used by two courses (Metodi e Strumenti di Coprogettazione di Sistemi Elettronici eOttimizzazione di Sistemi Elettronici) for teaching HW/SW codesign and related subjects. It only requires MATLAB/Simulink running on Windows or Linux computers and some FPGA evaluation board.
