Hardware Components

• In Kathryn, hardware components refers to both physical and logical elements of the hardware design model and they are internally composed of 6 major types.

• Type	description
  Reg	storable hardware component, only sensitive to posedge clk src: src/model/hwComponent/register/register.h
  Wire	non-storable hardware component, sensitive to all signal propagation src: src/model/hwComponent/wire/wire.h
  Value	constant value src: src/model/hwComponent/value/value.h
  Nest	concatenate hardware components in single variable src: src/model/hwComponent/expression/nest.h
  MemBlock	array storable hardware component, only sensitive to posedge clk src: src/model/hwComponent/memBlock/MemBlock.h
  MemBlockAgent	the indexer of the Memblock, storation sensitive to posedge clk, retrieve sensitive to all signal src: src/model/hwComponent/memBlock/MemBlockAgent.h
  expression	represent the combitional logic src: src/model/hwComponent/expression/expression.h
  SliceAgent	slice hardware component src: src/model/hwComponent/abstract/slicable.h

Hardware Component Structure

• This section illustrates how hardware components are structured.

• AssignOpr<H> manages interface for designers to assign the value to its element.
• Assignable manages the signal behavior for its element.
• Operable provides interface for signal operation such as bitwise, arithmethic, etc.
• Slicable<H> manages bit slicing for each element.
• AssignCallbackFromAgent<H> provides interface for interacting with Slicable<H>
• Identifiable manages names, component id, localization for its component.
• HwCompControllerItf provides communication between its component and model controller
• ModelDebuggable provides interface for debuggable.
• LogicSimEngineInterface provides interface for letting simulation engine to retrive model meta-data
• LogicGenInterface provides interface for letting Verilog Generation engine to retrieve model meta-data
• MemSimEngineInterface provides interface MemBlk for letting simulation engine to rertrive model meta-data
