15    level the COACH framework is a black box. The deliverables are documents
16    specifying: how to feed COACH (the inputs), how to use COACH (the design flow),
17    what is generated (the outputs).
18    %(definition of the generic architecture of the
19    %MPSoC and its 3 targets hardware mapping).

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