Abstract: A solution is the iRiser. The iRiser is a PCIe riser, designed to work with SANBlaze test systems but capable of operation in any PCIe slot on any computer. The iRiser includes a dedicated ASIC or programmed FPGA that cycles any of 32 signals, including power and reset, and samples power at up to 1 million samples per second, to any connected PCIe devices (such as sixteen NVMe drives under test in a SANBlaze test system, or more if larger testing systems are used). This allows precise insertion of any signal, including power and reset, at any desired testing point, and precise measurement of power drawn during any test condition, including transitions such as power on/off, reset, and low power state returning to running state. The iRiser can write measurement data to a host controller through direct memory access, providing the data synchronized to precise test conditions with zero overhead.
