Abstract
A system and method of testing IP cores contained in a system-on-chip integrated circuit is disclosed. An operation command is received on an input/output port of the circuit. The operation command includes an operation code component, data component(s), and expected time component. The received operation command is processed to supply test data to each of the IP cores being tested. Result data is received in response to the supplied test data from each of the IP cores being tested. The result data is processed and from the processed result data is generated a status data packet. The status data packet includes the operation code component and a status flag component and is provided on the input/output port.
