Introducing the PMBus Standardized Configuration File
PMBus Standardized File
Manufacturers need one file format from each PMBus vendor
This will enable a single tool to be used during test
XML file structure chosen for familiarity among vendors

Work Flow
5
PMBus defines standardized file format and structure
Customer uses vendor tool to configure PMBus product
– For specific system
Each vendor tool will output standardized file
– Product part number
– Target address
– Configuration commands
Manufacturing uses files for system board configuration
– Configuration is standardized

Introducing the PMBus Standardized Configuration File
Value to PMBus Customer
• Use vendors’ tool to configure product
– Each tool outputs standardized configuration file
– Each file targeted for specific device/address in system
• Test facility can use standardized files with single SMBus tool
– Standardized files parsed in same way
– Target socket information included
