On-Die Power Rail Measurements: Setup and Best Practices
Accurate on-die power rail measurements depend on proper sense-line design, differential probing, and careful test setup at the package level.
Educational content about using serial data signaling and oscilloscopes for validating and debugging serial data, whether it be low-speed serial data used in embedded systems (e.g., I2C, SPI, UART) or high-speed serial data signaling (e.g., PCIe, USB, DisplayPort).
Use serial decoding and digital-to-analog conversion techniques to track inaccessible sensor data and correlate it with system behavior in embedded designs.
Channel equalization uses transmitter and receiver techniques to counteract losses, reduce ISI, and improve signal quality in high-speed data links.
Transmit de-emphasis enhances eye diagrams by reducing inter-symbol interference, improving signal clarity at the cost of lower overall amplitude.
Continuous Time Linear Equalization (CTLE) enhances high-speed serial signals by compensating for channel loss, improving eye openings while balancing noise performance.
S-parameters allow engineers to model, remove, or simulate channel effects in high-speed serial links, helping diagnose signal degradation and improve performance.
TDME oscilloscope software enables engineers to measure serial bus performance and convert encoded data into analog waveforms for deeper debugging and analysis.
Eye diagrams generated from serial decode data help engineers visualize jitter, noise, and signal integrity issues in high-speed digital communications.
