Too bad no one responded in this thread. I can't understand when to use a particular pin type. I understand that the resistor terminals should be an analog type, but I don't know what type should be input and output terminal of Op-Amp.
Can someone explain to me when to use each specific pin type?
Thanks in advance.

Please find below a description of all Pin Types.
IN (Input) : Digital input pins.
OUT (Output) : Digital output pins that are not TRI (Tristate), OEM (Open emitter), or OCL (Open collector).
BI (Bidirectional or Bidir) : Digital pins that are both input and output (process input and output signals).
ANALOG (Analog) : Pin type used on Analog devices and also for Analog pins on digital devices (for example, DAC output pins and ADC input pins).
OCL (Open collector) : Open collector output pin.
OEM (Open emitter) : Emitter coupled logic (ECL) output pin.
TRI (Tristate) : Digital three-state output pin.
POWER : Supply pin, typically used for power pins on symbols (positive and negative rails). Apply this pin type to positive and negative tap symbols.
GROUND : Ground pin, typically used for ground pins on symbols. Apply this pin type to ground tap symbols.
TERMINAL : Terminal pin for VHDL-AMS (Analog Mixed Signal).
Pin Types are important for Design Rule Checking which is performed through the Verify Utility in DxDesigner. A lot of these checks rely on the Pin Types particularly Power and Ground checks but also connectivity checks. For example you can check that an OEM pin is pulled down as expected or that two output pins are not connected together.
The most used pin types are: IN, OUT, BI, ANALOG, POWER and GROUND.
Some people add TRI, OEM and OCL.
The TERMINAL Pin Type is rarely used in the context of a PCB design unless you run functional simulation in VHDL-AMS (Mixed signal).
I hope it helps.
Thank you very much!
It helps me a lot
