If your goal is to simulate two microcontrollers talking to each other:

Simulation runs extremely slow.

Link the TXCAN and RXCAN pins of the MCP2515 to the respective pins on the MCP2551 transceiver.

Let’s be honest from the start: If you search in Proteus’s component picker, you won’t find “MCP2515” listed. This gap is a major source of frustration, and it’s why community‑created libraries are so important. Unfortunately, many of those community libraries are incomplete, buggy, or entirely missing the simulation behavior—they only provide a schematic symbol without actual functionality.

However, if you specifically need the MCP2515 hardware interface for code logic:

Two Arduino Uno nodes (simulated in Proteus) connected via an MCP2515 + MCP2551. Node A sends ID 0x100 (Priority: Low). Node B sends ID 0x001 (Priority: High). Both start transmitting simultaneously at 500kbps.

Some libraries are built specifically as a "CAN Shield" block, making your schematic much cleaner. Where to find them?

Our enhanced MCP2515 library for Proteus addresses these limitations and provides a more accurate and efficient simulation experience. Some of the key features of this library include:

For the best performance, pair your Proteus simulation with these high-performing firmware libraries: Library Name Key Performance Metric Professional/High-Speed 100% bus capacity at 500kbps. Longan Labs MCP CAN Easy setup; supports OBD-II and masks/filters. Seeed Studio CAN-BUS Shield Integration Optimized for Seeed hardware but works well in simulation.

Even with a better library, Proteus simulations can display errors if the configuration parameters are incorrect. Can’t copy the link right now

Ensure the MCP2515 model is configured to the correct oscillator frequency (typically 8 MHz or 16 MHz).

Ensure the application is completely shut down.

If you have ever designed a Controller Area Network (CAN bus) system for automotive, industrial, or robotics applications, you know the drill: write the code, flash the hardware, test, fail, debug, repeat. This cycle is slow and expensive.
