    Abstract: A method and apparatus for inserting antenna diodes into an integrated circuit design is described. During the design process, diode cells are placed in filler cells of the integrated circuit design, but left unconnected. Subsequently, when an ECO is received requiring antenna diodes to be inserted in the integrated circuit design, only metal mask changes are required to connect the diode cells to gate electrodes of specified transistors or cells. Since the diode cells are already part of the original integrated circuit design layout, it is not necessary to perform a re-layout of the design cells with the diode cells performing antenna diode functions, thereby speeding up the EDA redesign process as well.

    Abstract: A method for allocating wireless communication resources in a distributed antenna system, in which the reuse factor of the wireless communication resource is further reduced and the utilization efficiency of the wireless communication resources is improved. In a group of service areas joining as a node in the system, the coverage area of each service area is divided into a central region and a boundary region, with each central region forming a central region allocating unit, and the boundary regions of a pair of adjoining service areas forming a boundary region allocating unit; each central region allocating unit is allocated with the same wireless communication resources and the quantity thereof is decided by the ratio of the area size of said central region to the area size of said service area, and also the quantity of all usable wireless communication resources in the system; each boundary region allocating unit is allocated with different wireless communication resources and the quantity thereof is decided by the remaining wireless quantity of wireless communication resources after the quantity of all usable wireless communication resources in the system minus the quantity of the wireless communication resources allocated to the central region allocating unit, and also the number of said boundary region reallocating units; and in a different group of service areas joining at one node, all usable wireless communication resources in said system are reused by the same allocating mode.

    Abstract: A selective IPO procedure based on the concept of a “timing violation potential” prioritizes the components and nets in a critical path. User input criteria is used to select the components or nets (or both) which have the larger “timing violation potential;” only those components and nets are then operated on. After a selective IPO step, the total number of critical paths is reduced, as well as the worst negative slacks (WNS) of the critical path compared to the traditional IPO method.
