I agree but I also would like to add. To further ensure that the test data is reliable, testability should be included in the early phases of the design. This would include using test points in strategic locations on the PCBA, high end testing equipment and custom software to automate different scenarios together to identify any issues that may be present. Without testability in mind, testing could end up being costly.

The problem can be tackled in various ways. Initially, controlling the requirements is key, addressing each solution to meet them, applying tests to verify each stage, even in prototypes, integrating the proposed solutions, and establishing a complete set of tests. Although simplified, there are tools that enable control and assist in delivering results and documentation.

In addition to properly calibrated test equipment, you can also compare against some form of SI analysis. When testing in a STE, try to mimic the target hardware as much as possible, e.g. if an onboard FPGA is going to communicate with an offboard FPGA, make your STE actually have the target, or similar, FPGA with a lean build to test the IO. And lastly, include testpoints upfront. Especially on clock signals and voltage levels, without compromising SI. If you're expecting a stable clock with clean edges, and are getting tons of jitter, easy fix. And lastly, don't just test one board. Test the entire first batch. First article inspection isn't limited to one board.

Include rigorous testing protocols comprising automated and manual inspections, utilisation of high-quality calibrated equipment, and meticulous documentation of test procedures and results. Additionally, standardising test environments, ensuring testing personnel competency, and verifying data through statistical process control and peer review are vital. Conducting regular audits and reviews, sourcing components from reputable suppliers, and incorporating design for testability features into circuit design also contribute to data integrity. Furthermore, adherence to industry standards, utilisation of automated testing software, and implementation of Failure Mode and Effects Analysis (FMEA) enhance testing reliability.

I would say that one need to record the each and every requirement which resulted in the current design. Test the design against these requirements.One has to perform extended test cases/negative test cases/worst test cases based on the requirement.Through this we can have test coverage ensuring that all design requirements are covered.

Reliability is key in complex electronic circuit design testing. 1. Ensure that the tools and equipment are calibrated and up to date for correct measurements 2. Ensure the test bench and Jig is validated for correct output. 3. Perform simulation and test the circuits with equipment tools. Ensure the output values from both are almost the same. 4. Perform automation testing, record the data. Check the values with tools randomly to ensure integrity. 5. Use different input values , and check the output consistency. 6. Check the accuracy and reproducibility of data.

The technology is as good as the people who use it! Knowledge, training, experience using the correct instruments and knowing how to read data allows for potential insight into the smallest possible data collection error. With quality and certified, calibrated devices for the required purpose, secondary reading errors are reduced to an additional minimum. All of the above together will make our project useful for society and the company and safe for the staff who use them as well as desirable for a cleaner environment.

Na confiabilidade dos dados de teste em projetos de circuitos eletrônicos, um dos caminhos para isso é a engenharia reversa, para entender a fundo o funcionamento de componentes e do design do circuito, parao identificar possíveis falhas e oportunidades de melhoria. Outro passo crucial é a repetição dos testes em diferentes cenários. No ambiente automotivo, os circuitos enfrentam desafios como vibrações e interferências. Repetir os testes, garante que o circuito funcionará de forma confiável, e é importante realizar o teste por amostragem, verificando mais de uma placa. Isso nos permite comparar o desempenho entre unidades de produção distintas e detectar variações na qualidade do produto final.

Testing can only go so far. In complex analogue circuits, ensure, at design time, that no capacitors will need to charge, from power-up to the point where the circuit reaches steady state stability. In other words, the entire circuit should be already stable even as supply voltage is rising to its final value. Often this involves matching filtering caps to ground with filtering caps to V+, ensuring the node between the caps is at V+/2 as the circuit reaches stability, by calculation. Circuits where nodes at arbitrary voltages have capacitors to ground, cause those capacitors to have to charge during power-up. This type of sloppy design causes circuit instability on power-up and during brownouts, and are more sensitive to V+ variance.
