Systems, methods, and computer program products directed to testing a System-in-a-Package (SIP) using an Automatic Test Equipment (ATE) machine. A functional representation of one or more tests to be performed in the SIP is loaded in a memory located on a load board, the load board located on the ATE machine. A test controller located on at least one of the SIP and the load board is caused to retrieve and store the one or more tests to be performed in the SIP. The test controller is instructed to conduct the one or more tests in the SIP.
