Embodiments of apparatuses, systems, and methods are described for a machine-readable medium having instructions stored thereon, which, when executed by a machine, to cause the machine to generate a representation of an apparatus. The apparatus includes a bridge agent, a first interconnect, and a second interconnect. The bridge agent is configured by bridge control signals to control transmission of a communication between the first interconnect and the second interconnect. The representation may be a sequence of instructions written in a programming language to mimic in a computer simulation environment attributes derived from a projected fabricated hardware instance of the apparatus.
