PMBus (Power Management Bus) Protocol Validation
Soliton can generate a full-fledged timing, voltage, clock stretch behavior, and fault tolerance report for the PMBus interface on a chip. The solution can skew bus timing parameters, sweep bus voltage levels, verify and measure clock stretching, induce bus timeout, induce spikes/glitches, induce packet formation faults and measure bus timing parameters. The solution is compatible with PMBus specification version 1.3.1.
Customers can ship 3 DUT boards containing their desired slave device to Soliton Technologies and we will characterize the DUT and send the customer a comprehensive PMBus Validation Report within a cycle time of 1 week.
