I checked cyclone5.ibs file and noticed that "lvcmos_rtpio_d16s1" and "lvcmos_rtpio_d16s1_p" is not listed in the ibis file.


According to the Cyclone5 IBIS Models UG, "lvcmos" refer to 3.3 V LVCMOS and according to the Cyclone V Device Handbook, 3.3 V LVCMOS supports current strength setting of 2mA only. So, this is confirmed that lvcmos models should not have "...d16.." because this refers to 16mA current strength.
