HWT design workflow

HWT structure

• hwt.interfaces - Collection of most essential interfaces like Signal, Clk, Rst, Rst_n...

• hwt.serializer - Converters from internal representation to VHDL/Verilog/SystemC/IPcore/...

• hwt.simulator - RTL based simulator and simulator utils.

• hwt.synthesizer - Tools for generating of internal representation from HWT hw description.

• code - Contains most of code operations used in HWT hw descriptions like:

  • If, Switch and other statements,
  • advanced connection methods like fitTo, connect,
  • arithmetic operators and functions like slr, isPow2, log2ceil

• hwt.hdl - Classes which representing hdl structures like Entity, Architecture, RtlSignal, hdl types, etc. Object of these classes we call internal representation of HWT. Most of this module is quite low level but there are some part which you will surely use:

  • hwt.hdl.typeShortcuts - this file contains definitions of most used hdl types which can be used in HWT hw descriptions

  • hwt.hdl.constants - Most used constants like Time, Direction, etc...

Internals

• hwt.pyUtils - general purpose python utils

• FAQ

HWToolkit tutorials

• Basics of hierarchical designs

• Serializers

Simulation and verification
