A system for recreating a data background to test memory designs for macros includes a macro, a first multiplexer, and a second multiplexer. The macro includes a plurality of flip-flops. The first multiplexer has a first input coupled to the macro output and a second input coupled to an inverted version of the macro output. The first multiplexer receives a control signal that selects between the macro output and the inverted version of such output to produce a first multiplexer output. A second multiplexer, coupled to the first multiplexer output and a normal scan input signal, receives a select signal that selects between the first multiplexer output and the normal scan input signal to generate a second multiplexer output, which is coupled to the macro input. A method for recreating a data background to test memory designs for a macro size defined by a plurality of flip-flops also is described.
