hwt.synthesizer package

Sythesizer converts hwt.hwModule.HwModule instances to HDL objects.

hwt.synth.to_rtl() function is one of examples how to use this module. The conversion of hwt.hwModule.HwModule instances happens mainly in hwt.hwModule.Hmodule._to_rtl() which calls other optimization and transformations stored in :hwt.hwModule.HwModule._target_platform.
