The System Management Bus (SMBus) is a two-wire interface through which various system component chips can communicate with each other and with the rest of the system. It is based on the principles of operation of I2C. SMBus provides a control bus for the system to pass messages to and from devices instead of using individual control lines, helping to reduce pin count and system wires.
As a part of product validation, it’s important to validate the product’s conformance against the protocol specification to ensure the interoperability of the product. As the complexity of the protocol and product increases, the validation time of the protocol interfaces also increases which in turn reduces the RTM. Performing the protocol conformance testing in the traditional way needs a lot of time and effort.
Soliton’s SMBus Slave Validation Suite is an off the shelf validation tool using NI’s PXI Platform, which helps to validate the devices’ compliance with timing and electrical specifications of the SMBus protocol. The tool can also validate the devices tolerance to and recovery from a variety of SMBus faults & exceptions and provides a comprehensive set of reports. Users have claimed that, using this automated solution for SMBus slave Validation has brought down the test time/ validation time from a few weeks to a couple of days.
* Rise/Fall time is only controlled in places where Master driving using controlled slew signals.
No, this is not always the case. If your customer has a very narrow use case, or your chip’s SMBus IP is the same as a previously tested chip, then it is possible that you do not need the extensive validation that our service/suite provides.
While this is certainly an option, we expect that it will take a highly experienced automation engineer between 3-6 months to create the first version of a similar tool. To create a robust and flexible tool takes experience, and we have been improving this tool over the last 3 years since release. We believe it is worth the cost to skip the learning curve and avail of our comprehensive report or validation suite.
The 6570 module is a general-purpose programmable pattern generator and acquisition device with deep memory. It can be programmed using LabVIEW or other programming languages to emulate any synchronous digital protocol with 5ns resolution and 39ps line skewing resolution. NI’s PXI chassis supports high bandwidth and synchronization-friendly control and read back from a huge variety of digital, analog, and special-purpose modules in a compact form factor.
Currently, the tool supports SMBus spec version 3.1
The tool comes with a flexible test editor that allows the user to create custom test cases using the SMBus functions provided.
Yes, The tool comes with readily available test scripts which can be used for validation after entering the device-specific details
