The "best" library for Proteus is generally considered to be the integrated VSM (Virtual System Modeling)

Use DC Voltmeters on the CANH and CANL pins. In a recessive state, both should read roughly 2.5V. In a dominant state, CANH should rise to ~3.5V and CANL should drop to ~1.5V. Troubleshooting Common Errors "Simulation Advisor: Model 'MCP2551' not found" void setup() Serial

Connect directly to the virtual CANH bus lines.

The MCP2551 is a high-speed CAN (Controller Area Network) transceiver from Microchip Technology that serves as a critical physical layer interface between a CAN protocol controller and the physical CAN bus. This fault-tolerant device is fully compliant with the ISO-11898 standard and is widely used in automotive electronics, industrial control systems, and embedded networks. The MCP2551 transforms the digital signals from a CAN controller (such as the MCP2515 or a microcontroller with built-in CAN) into differential signals suitable for robust transmission over the bus cabling.

For purely functional simulation—where you only care about the data being transmitted and received, not the precise differential voltages—you can often bypass the specific MCP2551 model. Instead, you can directly connect the TX and RX pins of your CAN controller (like the MCP2515) to the TX and RX pins of another simulated node. This treats the bus as a simple digital connection, which is often acceptable for protocol and firmware testing. In a recessive state, both should read roughly 2

: CAN simulations consume high CPU overhead. Minimize the number of active virtual instruments or increase the simulation time-step in your global settings.
