Shouldn't these be added to: https://github.com/siliconcompiler/lambdalib/blob/6e1a80c592c1f5ac8d456274a75609f8d119c802/lambdalib/padring/rtl/la_iopadring.vh lambdalib/lambdalib/padring/rtl/la_ioside.v Line 227 in 6e1a80c |

- Consistent with previous naming methodology for iolib
- Needed to be able to support proper rx differential cells that allow for pseudo differential low skew digital signals to be sent to the core.

Updated header file and added support for differential digital RX signals at padring interface. |

The differential signal indexing is not implemented yet. I copy pasted it from the xtal cell which has never been tested. I will merge this and fix bug later. |
