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.iHdlConstrainPlacement 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.
