Dear Mahmood,
To create a new component your best friend is the source code. Use one of the
components as an example to understand what you need to do.
Each component is basically a CPP class that has a header file and a CPP file.
The header file defines input/output ports of the component and the parameters
that the component has (e.g. components/FastCMPCache/FastCMPCache.hpp).
The CPP file (usually {components_name}Impl.cpp:
components/FastCMPCache/FastCMPCacheImpl.cpp) includes the implementation for
the component. Here you will find what actions a component does when messages
arrive at its input ports.
Components are instantiated and connected together in the wiring file of the
simulator (simulators/CMP.L2SharedNUCA.OoO/wiring.cpp). The WIRE macro connects
an output port of a component to an input port of the other one.
Regards,
Mohammad
