Samenvatting

The Main question of the Thesis is: Which hardware and software is needed to test the ADC module of the EVA setup without the help of the EVA setup? Before answering the main question some background information is needed.
At NXP there is a bench test setup called the EVA. The EVA consist of several modules. If there is a malfunction in a board the board is normally replaced to be repaired at a later time. The module can be tested in the EVA setup but the work load is very high there is no time to test it in de setup. So the idea of an standalone tester was born.
For the design of the tester the SDM method is used. With this design method the assignment was split into smaller parts. By executing the different phases of SDM the tester was designed systematically.
The design is split in to two parts a hardware and software part.
The hardware part is designed with the following requirements;
Standalone (without the EVA set up) Self-test function Needs test pads to measure signals Connect to USB Connect to ADC module
Wrong power connection protection a diode in the + of the connection. The design of the hardware is based on these requirements. The hardware is meant to be in a test environment. The software is designed with the following requirements; GUI needs to be easy in use The ADC tester needs to be able to test the 96 channels individually.
Manual Testing
Automatic testing
The software is designed that someone with limited knowledge can still operate the ADC tester. With the hardware and software combined a working ADC Tester is created.
