1 Introduction
1.1 Overview
This ECU and Network Test Specification is designed to determine if a product conforms to specifications
defined in OPEN Specifications or related requirements. This specification is a collection of all test cases
which are recommend to be considered for automotive use and should be referred by car
manufacturers within their quality control processes.
Sucessful execution and passing all relevant tests gives a Device Under Test (DUT) a mimimum approval
that the device’s basic implementiations are done correctly.

This Test specification document is grouped in several chapters oriented on the scopes: “Automotive
Ethernet”, “TCP/IP Protocol Family” and “Automotive Protocols” which are described in chapter 1.3.
Tests are organized and identified with distinct IDs that relate to their scopes, and a unique
enumeration. For every scope introduction chapters explain common requirements on the Device under
Test, the Test Setup and parameters used by the following tests.
1.2 Feedback
Any feedback for correcting, improving or adding new content is welcome. We encourage to bring
forward this feedback in the regular meetings of the OPEN Alliance TC8. In case you are not an OPEN

1.4 Definition of Test Scopes
1.4.1 Test Scope Automotive Ethernet
Scope Automotive Ethernet includes the following ISO/OSI layers:
 Layer 1: Physical Layer OPEN Alliance BroadR-Reach (OABR)
 Layer 2: Data Link Layer, e.g IEEE Ethernet MAC + VLAN (802.1Q), ARP
1.4.2 Test Scope TCP/IP Protocol Family
Scope TCP/IP Protocol Family includes the following ISO/OSI layers:
 Layer 3: Network Layer, e.g. IP, ICMP
 Layer 4: Transport Layer, e.g. UDP, TCP, DHCP
1.4.3 Test Scope Automotive Protocols
Scope Automotive Protocols includes the following ISO/OSI layer:
 Layers 5-6-7: Application oriented layers, e.g. UDP-NM, SOME/IP, SD

2 Test Scope Layer 1 of Automotive Ethernet
2.1 Interoperability Tests
2.1.1 General
The following test specifications are adapted from [1] to fit the general requirements of an ECU.
2.1.2 Link-up time
(based on OABR_L1_IOP_22 of [1])
3 test cycles:
 Power on Golden Device
 Power on ECU
 Wake up ECU
OABR_LINKUP_01: Link-up time - Trigger: Power on Golden Device
Synopsis Shall ensure that the link is established within a given time without a high time
variation.
Prerequisites 1. The DUT is connected to a stable power supply.
2. The DUT must be operated in normal mode which means the DUT builds up the
link and sends any Ethernet messages.
3. The Test System provides special awake conditions for the DUT such as a wakeup
line or network management CAN messages if necessary.
4. If the DUT contains a switch all links have to be tested separately.
5. The mean start up time of the golden device is available: 𝑡
𝑟𝑒𝑎𝑑𝑦
Test setup The DUT must be connected to the golden device with opposite master/slave
configuration. The polarity of the communication channel must be correct. The power
supplies are controlled by the test system.

3. Polling of golden device’s status register. If link_control= active link: t =t
stop ActiveLink
4. Calculate the time t between power on and link up: t = t - t
up up stop start
5. Power off golden device.
