hwtBuildsystem.ioConstraints package¶
- class hwtBuildsystem.ioConstraints.ConstrainIo(intf: hwt.synthesizer.rtlLevel.mainBases.RtlSignalBase, pin_map, std: Optional[Union[hwtBuildsystem.vivado.xdcGen.XdcIoStandard, str]], ommit_registration=False)[source]¶
Bases:
hwt.constraints.iHdlConstrain
Placement constrain which specifies on which IO pin of the chip package will this signal be mapped to and which standard it will use and optionally also input clock frequency.
- Note
io standard specifies the voltange, logic type etc.
