In a typical setup, your microcontroller (e.g., a PIC, STM32, or Arduino) uses an MCP2515 CAN controller via SPI. This controller then connects to the MCP2551 transceiver, which finally connects to the CANH and CANL bus lines. For a complete and accurate simulation, you need both the MCP2515 and the MCP2551 in your Proteus library.
Connect to the RX pin of your CAN controller or MCU.
