摘要： The invention provides a functional module model for realizing optimal pipelining. The functional module model includes division line data representing division lines corresponding to positions where pipeline registers can be inserted and delay/area data representing the trade-off relationship between the delay and the area of each division area partitioned by the division lines. By using this functional module model, a pipeline register insertion position is selected among the division lines represented by the division line data, and the delay and the area of each division area are set on the basis of the trade-off relationship represented by the delay/area data. Thus, a pipelined circuit with a minimized area can be synthesized.

摘要： A characteristic of a MOS transistor is represented using an equivalent model. The equivalent model shows a connection configuration made up of an electric current source which supplies an electric current and a resistor element which is connected in parallel with the electric current source. The electric current is given by the equation of i=G.sub.m .multidot.(V.sub.GS -V.sub.T) for V.sub.GS .gtoreq.V.sub.T where G.sub.m is a coefficient, V.sub.GS is a gate-to-source input voltage of said MOS transistor, and V.sub.T is a given threshold voltage. A plurality of operating zones of the MOS transistor are defined according to the drain, source, and gate terminal voltages of the MOS transistor and are assigned respective values of the coefficient G.sub.m and respective values of the resistor element's resistance. By such a representation, the circuit equation of a semiconductor circuit that is analyzed can be represented in the form of a linear time-invariant equation. Semiconductor circuit performance characteristics can be analyzed and evaluated at high accuracy and high speed.

摘要： A gate wire is formed so as to extend from an active area to a separation, and an impurity diffused area is formed on each side of the gate electrode located on the active area. A contact member for connecting the gate wire to a first layer aluminum interconnection formed in an upper layer of the gate wire is in contact with the gate wire at a portion located on the active area. The utilization ratio of the active area is thus improved, and hence, the width of the separation can be minimized. In addition, by eliminating a mask alignment margin from the gate wire and suppressing the width of the gate wire not to exceed the width of the contact member, the occupied area of a semiconductor apparatus can be reduced.

摘要： An initial placement is performed based on a net list and a cell library. An optimum effective temperature Tc is derived based on a cost value obtained if the positions of two components, selected from a list of exchange candidates (where all the components are registered), are exchanged with each other and a cost value before the exchange is performed. A first component and a second component, adjacent to the first component, are selected from the list of exchange candidates and the positions thereof are exchanged with each other. And at the optimum effective temperature Tc, it is determined in accordance with a Monte-Carlo method using the cost values before and after the exchange whether or not the exchange is allowable. If it is allowable, the placement after the exchange is decided as a new placement. Otherwise, the placement before the exchange is decided as a new placement. Subsequently, new placements are decided N times for each component included in the list of exchange candidates, and candidate components, the exchange number M of which is equal to or larger than a predetermined number Nm (where Nm

摘要： During an optimization of an organization of mutually-related elements, an element organization is gradually changed toward an objective specification by local changes of the element organization. A value of an objective function depends on a degree of a nearness of the element organization to the objective specification. A redundancy function of a number of elements in an improvement group is determined in consideration of a fluctuation in the value of the objective function, so that suitable changes of the improvement group are performed by use of the definite redundancy. An intermediate element organization is rejected and accepted in accordance with the redundancy function value, so that a final element organization can be obtained in consideration of a global aspect of the element organization.

摘要： To reduce a circuit block in area, the present invention provides an LSI layout design method having a cell changing processing for reducing a pure wiring zone in area. By an input processing, circuit design information and cell library are entered. Then, a layout of cells arranged in a plurality of cell rows is designed by a cell placing processing. Then, the height of a wiring zone required between cell rows is estimated by a wiring zone height estimating processing. To reduce the area of a pure wiring zone other than the over-the-cell wiring zones, each of placed cells is changed, by a cell changing processing, to a cell having the same specifications and a different shape or a different terminal position. A layout of cell interconnection is designed by a wiring processing. Based on the layout thus obtained by the processings above-mentioned, a mask pattern is prepared and supplied by a mask pattern preparing processing.
