    • A method of fabricating a plurality of electronic circuits with transistors in schematic form in a customizable semiconductor integrated device, such as a base array, is disclosed. The base array has a plurality of chains of continuously electrically connected transistors, all of the same type, with the drain of a transistor connected to the source of an adjacent transistor. The schematic transistors are grouped by diffusion line tracing to form a plurality of groups. Each group of schematic transistors is assigned to physical transistors in the base array. The cost function associated with each group of physical transistors is calculated. The total cost function is optimized by changing the assignment of one or more groups of the schematic transistors to the physical transistors. The electrical interconnection from one group of physical transistors to another group of physical transistors is routed to form the physical layout of the circuit. Isolation transistors are also provided to isolate physical layouts of the circuit from one another or to provide isolation between groups of physical transistors where isolation is needed. The gate of each isolation transistors is connected to a voltage source thereby isolating the physical layouts of the circuits.
    • 公开了一种在可定制的半导体集成器件(例如基极阵列)中以示意形式制造具有晶体管的多个电子电路的方法。 基极阵列具有多个连续电连接的晶体管链,全部相同类型,晶体管的漏极连接到相邻晶体管的源极。 示意性晶体管通过扩散线追踪分组以形成多个组。 每组示意性晶体管分配给基极阵列中的物理晶体管。 计算与每组物理晶体管相关联的成本函数。 通过将一个或多个原理图晶体管组分配给物理晶体管来优化总成本函数。 从一组物理晶体管到另一组物理晶体管的电互连被路由以形成电路的物理布局。 还提供隔离晶体管以将电路的物理布局彼此隔离或者在需要隔离的物理晶体管组之间提供隔离。 每个隔离晶体管的栅极连接到电压源,从而隔离电路的物理布局。
