公开了一种用于电路设计的仿真系统。该系统耦合原理图编辑器和模拟器，以允许对被测设计进行增量更改，而无需事先关闭模拟器。该系统使用一种方法，该方法允许对设计进行大范围的改变，并为改变后的设计提供最终的网表。可以对原理图进行更改，包括更改层次结构、添加或删除组件（包括分级组件），在设计分级结构内的任何级别添加或删除信号，在设计分级结构内的任何级别添加或删除组件的互连，添加和删除任何组件类型的接口端口，用新组件替换现有组件（包括交换分层和行为描述），以及改变诸如器件延迟定时之类的参数数据。进行设计更改后，仿真将继续运行。该方法可以与硬件建模系统结合使用。
A simulation system for circuit design is disclosed. The system couples a schematic editor and simulator to allow incremental changes to a design under test without requiring prior shutdown of the simulator. The system uses a method which permits a wide range of changes to the design and provides a resulting netlist for the changed design. Changes can be made to the schematic which include changes in hierarchy, addition or deletion of components (including hierarchical components), addition or deletion of signals at any level within the design hierarchy, addition or deletion of interconnections of components at any level of hierarchy within the design, addition and deletion of interface ports for any component type, substitution of a new component for an existing one (including swapping hierarchical and behavioral descriptions), and alteration of parametric data such as device delay timing. The simulation continues to run after design changes are made. The method may be used in conjunction with hardware modeling systems.
