Familiar with HW IP datasheets and user guides, extract critical information regarding register access sequences, expected operation sequences, and their corresponding results, including Register maps, Timing diagrams, Command sequences
Develop test vectors based on the specifications outlined in the datasheet. Consider valid and invalid input scenarios, edge cases for register settings, timing and sequence requirements; enhance the test vectors by incorporating variations in conditions (temperature, voltage) to ensure robustness.
Conducting tests on hardware platforms. Utilize appropriate lab equipment (oscilloscopes, logic analyzers) for testing. Employ debuggers to monitor register accesses and to trace execution paths during testing.
Gather data from tests, noting any discrepancies from expected outcomes. Perform Function Validation by Assessing whether the observed results align with the expected results from the datasheet/user guides. Perform Failure Analysis and Identify potential root causes for any failures, such as timing issues, incorrect register settings, or environmental factors.
Have a hands-on understanding of protocols like JTAG, SPI, I2C, and UART, focusing on Signal integrity, Communication sequences; Use tools to probe these interfaces and verify correct operation during the bring-up phase.
Utilize oscilloscopes to inspect eye diagrams and other analog characteristics to assess signal integrity of high-speed IOs. Measure jitter, rise/fall times, and overall signal quality to ensure compliance with specifications.
Design and implement simple test fixtures using Reference design kits, cables and connectors to facilitate testing of the hardware IP. Ensure the test fixture can accommodate various configurations to test different scenarios.
