AHB Multilayer

In the multilayer environment,  i found a interconnect matrix with interface signals on the Master side having a hsel signal. Can anyone specify the significance of it. A basic doubt is that apart from the interconnect matrix do we hav any slave mux and decoder.

    hi jd,

            The example which i was speaking about is present in the Cadence UVC. There is no information about the internal functionality of the interconnect matrix and only the i/o ports are specified. The internal functionality is actually emulated. Here hselS0 signal is an input to the Interconnect Matrix on the Master side and  hselM0 signal is an output on  the Slave side. The output is understandable, where it can be direclty connected to a Slave. Should the input hsel on the Master side be tied to '1'. Apart from the other common signals on the master side, hreadys0 is present, which is a input to the matrix on the master side. My doubt is how can hreadyout be driven by the Master and while connecting standard AHB Masters, how it should be connected.
