Dear TI team,
I'm using IBIS model in HSPICE and encountering error : "**error** (b_lvlshftd:15) Buffer is power on with voltage source connected to node PU, where File = txb0304.ibs, Model = IO_33_OS"
Seeking for the right way of connection.
Below is the hspice deck with using ibis model,
Thank you,
