     60at 214\,M\$.
    6261This market is dominated by Multi-core CPUs and GPUs based solutions and the expansion
    6362of FPGA-based solutions is limited by the lack of design automation.
     63\\
    6464Nowadays, there are neither commercial nor academic tools covering the whole design process
    65 from the system level specification to the bit stream generation.
    66 % IA to Alain: J'ai remis (et ameliore un peu) ca car sinon le Consequently 20 lignes
    67 %              au dessous n'a pas de sens.
    68 % Deplus dans les demandes ANR de la section, il est demande: analyse de la concurrence
    69 By using SOPC Builder~\cite{spoc-builder} from \altera, designers can select and
    70 parameterize components from an extensive drop-down list of IP cores (I/O core, DSP,
    71 processor,  bus core, ...) as well as incorporate their own IP.
    72 Designers can then generate a synthesized netlist, simulation test bench and custom
    73 software library that reflect the hardware configuration.
    74 %% Steven disagree : the C2H compiler bundled with SOPCBuilder does a pretty good job at this.
    75 %% IA: ces lignes ont ete verifiees et corrigée pa \altera. De plus C2H est plutot limite.
    76 Nevertheless, SOPC Builder does not provide any facilities to synthesize coprocessors and to
    77 simulate the platform at a high design level (systemC).
    78 In addition, SOPC Builder is proprietary and only works together with \altera's Quartus compilation
    79 tool to implement designs on \altera devices (Stratix, Arria, Cyclone).
    80 PICO~\cite{pico} and CATAPULT-C~\cite{catapult-c} allow to synthesize
    81 coprocessors from a C++ description.
    82 Nevertheless, they can only deal with data dominated applications and they do not handle
    83 the platform level.
    84 Similarly, the System Generator for DSP~\cite{system-generateur-for-dsp} is a plug-in to
    85 Simulink that enables designers to develop high-performance DSP systems for \xilinx FPGAs.
    86 Designers can design and simulate a system using MATLAB and Simulink. The tool will then
    87 automatically generate synthesizable Hardware Description Language (HDL) code mapped to
    88 \xilinx pre-optimized macro-cells.
    89 However, this tool targets only DSP based algorithms.
    90 \\
    91 Consequently, a designer developping an embedded system needs to master four different
    92 design environments:
    93 \begin{enumerate}
    94   \item a virtual prototyping environment such as SoCLib for system level exploration,
    95   \item an architecture compiler (such as SOPC Builder from \altera, or System generator
    96   from \xilinx) to define the hardware architecture,
    97   \item one or several HLS tools (such as PICO~\cite{pico} or CATAPULT-C~\cite{catapult-c}) for
    98         coprocessor synthesis,
    99   \item and finally backend synthesis tools (such as Quartus or Synopsys) for the bit-stream generation.
    100 \end{enumerate}
    101 Furthermore, mixing these tools requires an important interfacing effort and this makes
    102 the design process very complex and achievable only by designers skilled in many domains.
     65from the system level specification to the bit stream generation neither for embedded system design
     66nor for HPC.
