Problems solved by technology
Conventional test systems and methods often have various limitations
[0005] Conventional CPU platforms (for example, Intel x86 architecture platforms, etc.) usually have limitations on input and output I / O space
I / O space limitations in turn limit the number of devices that can be tested in parallel on the same interface
For example, a UART device sitting behind a PCIe switch usually does not allow more than 10 or 12 devices to be used in parallel

The present invention provides an enhanced auxiliary interface systems and methods. Presented embodiments facilitate efficient and effective flexible implementation of different types of testing procedures in a test system. Presented embodiments facilitate efficient and effective flexible implementation of different types of testing procedures in a test system. In one embodiment, an enhanced auxiliary interface test system comprises a load board, testing electronics, controller, and memory mapped interface. The load board is configured to couple with a plurality of devices under test (DUTs). The testing electronics is configured to test the plurality of DUTs, wherein the testing electronics are coupled to the load board. The controller is configured to direct testing of the DUTs, wherein the controller is coupled to the testing electronics. The memory mapped interface is configured to implement multiple paths to access a central processing unit (CPU) on the controller and enable testing of multiple DUTs in parallel.
Description
[0001] related application [0002] This application claims benefit and priority, which application is incorporated herein by reference. technical field [0003] The invention relates to the field of electronic testing. Background technique [0004] Electronic systems and devices have contributed significantly to the advancement of modern society and have facilitated increased productivity and reduced costs in analyzing and communicating information in a variety of business, scientific, educational, and entertainment applications. Conventional testing systems and methods often have various limitations. [0005] Conventional CPU platforms (for example, Intel x86 architecture platforms, etc.) usually have limitations on input and output I / O space. I / O space limitations in turn limit the number of devices that can be tested in parallel on the same interface. For example, a UART device sitting behind a PCIe switch usually does not allow more than 10 or 12 devices to be used...
