Test » Automotive BCU
Functional testers for automotive BCU products are high complex equipments that require customized electronic developments and adaptions to achieve the EOL timing requirements, component and functions test coverage. A customized BCU Functional tester is the best solution to guarantee the test coverage quality required by the end customers at an acceptable cost and test time.
An example of the automotive BCU tester tests the following variables:
· End customer: German automobile manufacturer.
· 3 microcontrollers, around 400 inputs, 300 outputs and more than 4000 components.
· Output load drivers by single and multiple activation points, concerning FETs, relays, voltage and current feedbacks, output pull-ups and pull-downs.
· Inputs: analog, digital, resistive, capacitive and pulsed.
· Pass-troughs.
· Internal logical circuitry.
· Limp home and security circuits.
· Wake-up input sources and interruptions.
· Short circuits between adjacent pins.
· Open circuits.
· Presence, absence and value of certain components.
· Sleep and operating current consumption.
· Different typology of communications: Ethernet, FlexRay, CAN and LIN.
· Short circuits between adjacent connector and component pins.
