6 months agoHello,
Based on my findings and discussion with internal team, the IBIS models below are expected to exhibit similar behaviour because, based on the HSPICE models for Cyclone V device, the bit settings for the 2mA current strength of 3.3 V LVCMOS and the 16mA current strength of 3.3 V LVTTL are the same. You can refer to the drive_select_IO.lib file located in the lib folder of the CV_GPIO_hspice_model_v2p0 for the bit settings for each drive strength setting.
