A reconfigurable instruction cell array (RICA) is provided that includes a plurality of master switch boxes that are configured to read and write from a plurality of buffers through a cross-bar switch. A master built-in-self-test (MBIST) engine is configured to drive a test word into the write path of at least one master switch box and to control the cross-bar switch so that the driven test word is broadcast to all the buffers for storage. The MBIST engine is also configured to retrieve the stored test words from the buffers through a read bus within the cross-bar switch.
