#   Description:
#   Description:
#     This class represents a core definition.
 
#     It is one of the central classes and holds data,
 
#     which is used to describe and instanciate this core.
 
#     In general, instances of this class desribe a core,
 
#     it's interface and parameters as well as the files,
 
#     which are required for synthesis/simulation.
 
#
 
#     In addition to this core, there exist CoreInst,
 
#     which represents a concret instanciation of a definition
 
#     (see core_inst.rb).
 
#     This class adds two fields to SOCMaker::Component:
 
#         - hdlfiles           : hash of SOCMaker::HDLFile (mandatory,
 
#                                at least one file)
