Abstract
A method for operating a data processing system to generate a test for a device under test (DUT) is disclosed. The method utilizes a model of the DUT that includes a plurality of blocks connected by wires and a set of control inputs. Each block includes a plurality of ports, each port being either active or inactive. Each block is also characterized by a set of constraints that limit which ports are active. The active ports of at least one of the blocks are constrained by one of the control inputs. A test vector having one component for each port of each block and one component for each control input is determined such that each set of constraints for each block is satisfied. The test vector defines a test for the DUT.
