CAN-VIP
CAN2.0 & CAN-FD Verification IP

CAN-VIP is a comprehensive VIP package for CAN 2.0 and CAN FD controllers. SoC and IP designers use this CAN VIP package to ensure complete verification of their designs and full protocol and timing compliance.

CAN-VIP implements a ready-to-use set of models, protocol checkers, and compliance testsuites in 100% native SystemVerilog and UVM. It supports the latest relevant specifications, including CAN 2.0 Part A/B and FD modes and Time-Triggered CAN.

A 30-day free license for CAN-VIP is included with each CAN-CTRL Controller Core delivery.

The complete bus functional CAN node model in the VIP package supports integration steps, transmitter and receiver modes (in-cluding multiple bit rates), inter-frame delay, and bit phase delay adjustment. It supports the random configuration of node type and bit timing rate, and includes APIs to preload and access sparse memory regions.

The BFM's frame class models all supported CAN frame formats and types. Its open and unencrypted timing class models all ap-plicable timing parameters, including randomize and modifiable. The BFM also performs error detection (callback, bit stuffing) and injection.

The testsuites included with CAN-Xactor include both Avery-developed directed and constrained random tests and the ISO 16845 conformance tests.

Controlling and executing the CAN bus model is straightforward, as shown in this example.

begin 
    acan_frame_class cmd = new; 
    ok = cmd.randomize() with { 
       frame_type inside {ACAN_FRAME_REMOTE, ACAN_FRAME_FDEXT}; 
       header.id == 4}; 
    assert (ok) else test_log.fatal("randomization failed"); 
    node_2.post_command(cmd); 
    cmd.wait_done(1ms, `acan_fline); 

    if (cmd.frame_error != 0) begin 
       $display(“Completion is not OK: %s”, cmd.sprint_error()); 
    end 
end
