Rambus Inc. uses a protocol adapter that provides the means to communicate with SPI, JTAG I2C and other proprietary interfaces over a common USB 2.0 interface to a host computer. This adapter is used to test the throughput and performance of various Rambus products. The goal of this clinic project is to design a USB 3.0 adapter on a PCB that communicates between a device under test and existing testing software with higher speeds.
