extract_const_val_as_const_var(val: HConst) → RtlSignalBase[source]¶: Create a constant variable with a value specified or use existing variable with same value

hwt.serializer.generic.indent module¶

hwt.serializer.generic.indent.getIndent(indentNum: int)[source]¶: Cached indent getter function

hwt.serializer.generic.ops module¶
