For simulating the MCP2515 CAN Controller in Proteus, engineers and hobbyists typically rely on external library files (.LIB and .IDX), as the component may not be natively included in all standard versions of the software. Top Blog Post & Resources
CAN Bus Shield for Proteus (GitHub): This repository includes a Proteus project (canbus.pdsprj) and a library specifically designed to simulate an Arduino CAN shield using the MCP2515.
Step 3: Copy the New Files
Paste the downloaded MCP2515.LIB and MCP2515.IDX into the LIBRARY folder.
3. If No Library Exists – Simulate Without MCP2515
Since accurate SPI CAN simulation is complex, use these workarounds:
