摘要： Clock skew can be reduced by suppressing fluctuation in wiring leads between the final stage clock buffers and the clock distribution circuit for supplying the clock. In view of attaining such reduction of clock skew, an upstream of the clock distribution circuit is formed in an H tree structure and the final stage is formed in a local fishbone structure. A plurality of main clock lines connected to the final stage buffer include a first main clock line and a second main clock line. The number of cell arrangement allowable rows where a plurality of first flip-flops for receiving the clock from the first main clock line are located is different from the number of cell arrangement allowable rows where a plurality first flip-flops for receiving the clock from the second main clock line are located.

摘要： A method and arrangement of locating cordless units in a wide area cordless telephone system is disclosed. A service area is previously divided into a plurality of small service zones and, a plurality of cordless units are provided for establishing communications with a system controller via a plurality of access stations. The system controller locates the cordless units and stores therein location data thereof. Each of the cordless units also stores the location data thereof applied from the system controller. A cordless unit issues a request signal which includes cordless unit location data. The request signal is received at an access station which in turn checks to determine if the request signal applied thereto is issued from a cordless unit whose location data indicates a service zone belonging to a predetermined service zone group. In the event that the cordless unit location data applied to the access station is found to fall within the predetermined service zone group, the access station relays the request signal applied thereto, together with a signal level of the request signal, to the system controller.
