Embodiments of the present invention provide a method of simulating a memory-based communication protocol for testing a simulated device. The method includes storing data in known locations of a host data buffer, where the host data buffer is implemented in a shared memory space, executing instructions of a first program to store a command in the shared memory space using a data structure including an index, an ID, and a memory location, executing instructions of a second program to read the command from the host data buffer, access the data in the shared memory space to perform an operation defined by the ID using the data, where a location of the data is indicated by the index, and send a completion indicator to the first program after the operation is complete.

Systems and methods for simulated device testing using a memory-based communication protocol

A method for monitoring communications between a device under test (DUT) and an automated test equipment (ATE) is disclosed. The method comprises programming an interface core and a protocol analyzer module onto a programmable logic device, wherein the programmable logic device is controlled by a system controller and is operable to generate commands and data to test a DUT, wherein the interface core is operable to generate signals to communicate with the DUT using a protocol associated with the DUT. The method also comprises monitoring data and command traffic associated with the protocol in the interface core using the protocol analyzer module and storing results associated with the monitoring in a memory comprised within the protocol analyzer module. The method finally comprises transmitting the results upon request to an application program associated with the protocol analyzer module executing on the system controller.
