\subtask This \ST specifies the COACH environment for the system designer. At this
    level the COACH framework is a black box. The deliverables are documents 
    specifying: how to feed COACH (the inputs), how to use COACH (the design flow),
    what is generated (the outputs).
    %(definition of the generic architecture of the
    %MPSoC and its 3 targets hardware mapping).

\subtask Backend HLS tools use a characterized macro-cell library to build the
    micro-architecture of a coprocessor. The characterisation of a cell depends
    on the target device. The role of this \ST is to define the macro-cells and
    to provite a tool that characterizes them automatically by synthesizing them
    and by extracting their delays. This is done by using RTL synthesis.

        \setMacroInAuxFile{specMacroCell}
