The IR2112 is natively available in many Proteus installations and can serve as a substitute. Pin differences exist, so verify compatibility with your circuit before proceeding.
If you only get a .lib file, it may still work; but for accurate simulation, the .mod SPICE model is critical.
Here is a comprehensive guide on how to implement the IR2110 properly in Proteus.
Accurate libraries simulate the nanosecond delays, ensuring that the high and low-side switches do not turn on simultaneously, which would cause a "shoot-through" failure. 3. Practical Applications Simulating the IR2110 is essential for several projects: ir2110 proteus library

1. Abstract
Proteus 8.15 and later versions now include native simulation models for the IR2110 and IR2113, a significant addition for power electronics designers. Users of older versions can update their software by navigating to to access the latest certified libraries from Labcenter. The IR2112 is natively available in many Proteus

Proteus VSM (Virtual System Modeling) allows you to analyze transient responses, observe switching waveforms on an oscilloscope, and catch short circuits virtually. Using the IR2110 in Proteus helps you:
The SPICE model for the IR2110 includes temperature and voltage-dependent parameters (e.g., +PARAMS: + T1=-40 T2=25 T3=125 + V1=10 V2=15 V3=20 ). When importing the model, ensure that all parameters are correctly assigned in the subcircuit call. Manually inspect the .SUBCKT line in the model file and confirm that the symbol used in the schematic has the same number of pins and parameter list. Here is a comprehensive guide on how to
Ensure you have placed a Simulation-ready model, or map the Infineon SPICE .mod file manually using the device properties panel as shown in Method 2. If you need help setting up your simulation, tell me: Which Proteus version are you running? What specific error message (if any) are you seeing?
Proteus is unequaled for MCU co-simulation (e.g., Arduino + power stage), but for pure analog gate drive simulation, LTspice is often more reliable.
