Low-speed serial interfaces such as I2C, SPI and UART are widely deployed in embedded systems, microcontrollers, automotive electronics, sensors, ADC/DAC interfaces, EEPROMs, and peripheral communication. These interfaces are extensively used in IoT, industrial automation, and automotive use cases. Though these interfaces are considered mature technologies, ensuring electrical conformance and protocol correctness remains critical for reliable system integration.
In this technical webinar, we will discuss practical approaches to validating both the electrical layer and protocol layer of I2C, SPI and UART interfaces using Prodigy Technovations exerciser and analyzer platforms. The session includes traffic generation, protocol decoding, trigger setup, automation workflows, and oscilloscope-based electrical validation techniques.
Introduction
- Overview of I2C, SPI and UART electrical characteristics and protocol layer validation.
- The PGY-I2C/SPI-EX-PD and PGY-UART-EX-PD tools validate both the electrical and protocol layers of I2C, SPI and UART interfaces.
- Automation of the test environment using API support.
This webinar focuses on combining these capabilities to create a complete validation workflow for design and post-silicon validation teams.
