Packeted protocol device test system

A test control device comprising:

• a plurality of functional self-test controllers configured to generate test traffic as part of running a plurality of functional test cases in parallel on a plurality of devices under test;
• an interconnect backbone coupled to the functional self-test controllers;
• a plurality of arbiters coupled to the interconnect backbone;
• a plurality of packeted protocol layer interfaces coupled to the arbiters, wherein the packeted protocol layer interfaces are configured to perform one or more protocol specific conversions between the test traffic and a device-specific packeted protocol of each of the devices under test, and further wherein the arbiters comprise circuitry that receives traffic from multiple sources and selects and limits traffic flow to the packeted protocol layer interfaces;
• and
• a plurality of payload checkers configured to verify responses of the devices under test to the functional test cases.

A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by processing circuitry to perform a plurality of operations comprising:

• configuring a plurality of functional self-test controllers in a test control device to run a plurality of functional test cases in parallel on a plurality of devices under test;
• arbitrating test traffic between the functional self-test controllers and a plurality of packeted protocol layer interfaces of the test control device, the arbitrating comprising routing the test traffic through an interconnect backbone of the test control device to an arbiter associated with one of the packeted protocol layer interfaces, wherein the arbiter comprises circuitry of the test control device that receives traffic from multiple sources and selects and limits traffic flow to the one of the packeted protocol layer interfaces;
• performing one or more protocol specific conversions between the test traffic and a device-specific packeted protocol of each of the devices under test;
• and
• performing payload checking between the packeted protocol layer interfaces and the devices under test to verify responses of the devices under test to the functional test cases.
