Everything you need to know about SPMI Protocol & debugging SPMI Protocol
What is SPMI Protocol?
SPMI (System Power Management Interface) is a MIPI (Mobile Industry Processor Interface) standard with 2-wire synchronous serial, bidirectional interface that connects the integrated Power Controller(PC) of a System on- Chip (SoC) processor system with one or more Power Management Integrated Circuits (PMIC) voltage regulation systems.
What are the benefits of MIPI SPMI?
SPMI has a wide range of applications that are spread across industries that needs better Power Management. SPMI is used in Smartphones, Wearables, other portable electronic devices. Smartphones & Wearables uses SPMI for controlling power of sensors. High-end smartphones already have multiple devices in the designs & can require up to 20 signal lines. Each of these having independent power pins can cause issues. Similarly, most portable electronic devices, would need a power management interface to optimize the energy consumption and reduce-pin count.
How to debug MIPI SPMI Protocol?
SPMI Protocol Analyzer (PGY-SPMI-EX-PD) is the Protocol Analyzer with multiple features to capture and debug communication between host and design under test. PGY-SPMI-EX-PD is the leading instrument that enables the design and test engineers to test the SPMI designs for its specifications by configuring PGY-SPMI-EX-ED as master/slave, generating SPMI traffic with time variation and error injection capability and decoding SPMI Protocol packets.
