Abstract

In an uppermost wiring plane of a mass-produced circuit of a micro-controller, contact faces are provided. To produce an emulation circuit a further wiring plane is added to the mass-produced circuit by way of which internal signals are carried to an external terminal. Acting as an interface is an output chip with further emulation logic capabilities which is applied to the emulation circuit in the manner of a flip-chip assembly.
