Abstract: A multiple of telephone or like communications signal transmission lines are interconnected in time division multiplex (TDM) mode by integrated semiconductor switching circuitry. Preferably, electronic solid state structure most suitable for embodying field effect transistors (FET) and like associated devices is arranged in modular chip components permitting extension to large numbers of transmission lines, as desired. Input or calling transmission line terminals are connected to node busses by FET switches in predetermined time sequence under control of a central processing unit. Preferably, a separate timing pulse train generating circuit is used for the switching operation. Output or called transmission line terminals are connected to the node busses in predetermined time sequence at which every calling line is sampled at least once each switching cycle. Signal bandwidth is adjustable by arranging the switching circuitry to sample a calling line one, two, or more times in each switching cycle. Conventional semiconductor structure inherently forms capacitors of substantial reactance between the node busses and points of reference potential. Circuitry is incorporated in the arrangement for discharging the capacitors prior to connecting the input signal lines to the node busses. The circuitry also incorporates FET switch elements arranged for isolating uncalled output terminals from the switching circuitry, and for short circuiting each pair of idle output terminals.

Abstract: An improved technique for processing large amounts of information and displaying that information graphically. The graphic display focuses attention to suspect areas employing colours and shading techniques to quickly focus the users attention to problem areas. The display shows selected net states across respective raster lines e.g. N21, N20 etc for a selected period of a VLSI circuit simulation. As the net states changes between logic 1, logic zero or an undefined state, the colour of the raster line changes. The large number of nets which can thus be displayed and the time sequence of changing states can enable rapid evaluation of the VLSI circuit performance and the existence of errors or faults in the design.
