Hi,
above post refers to IBIS models that don't exist in linked IBIS file, e.g. lvcmos_rtpio_d16s1. 3.3V LVCMOS doesn't support current strength above 2 mA.
Thus it's not clear what "identical definitions despite having different names" actually refers to?

lvcmos_rtpio_d2s1 and lvcmos_rtpio_d2s1_p differ in activating the clamp diode.
