The SV4E-I3C is an all-inclusive solution for I3C-based sensor interface development, test, and programming. Containing three instruments in one, this tool can act as a protocol exerciser for testing and debugging I3C slave or master devices. It can also act as a complete protocol analyzer with fine-resolution timing analysis and a full suite of conformance test capability. Finally, it contains a deep vector memory, which allows it to be used as a general purpose I3C device programmer. Device instances: integrates 4 parallel devices, each with its own independent protocol stack Timing resolution: 5 ns resolution on delay generation (exerciser) and time-stamp (analyzer) logic Protocol analysis: easily trigger on CCC’s and patterns for private and device to device communication, IBI, and hot-join Flexible: solution featuring I3C and I3C Basic protocol support with real-time voltage and timing controls Automated: scripting capability ideal for debug tasks, verification and full‐fledged production screening of devices and system boards
