双击Symbol View中的方块进入“Schematic View” 注意此时在在右下角的Design Analyzer窗口中显示为“Schematic View”。你会发现你的设计结构是由一些由通用的独立库中的组件构成的,这些组件位于Synopsys的GTECH库中。按下列顺序选择菜单,对设计进行约束: Setup - Scripts - 2.Constrain MY_CHIP 你会注意在Clock_In...
Figure 8. Node numbers added to the voltage divider circuit schematic. In these figures, zero is commonly used for the ground node, which is required for many SPICE circuit simulators. In the illustration of Figure 7, we can see how points in the circuit may be labeled with small pieces ...
打开上次画好的原理图,从原理图中删除电压源、地和负载电容,仅仅留下MOS管和端口,因为建立symbol只想纯粹表示反相器电路,而不希望把仿真用到的激励和负载电容包含进去。 在原理图界面:Create->Cellview->From Cellview,打开新建symbol窗口,一路确认,直到弹出框关闭,这时候就完成了电路原理图的symbol建立。其中symbol...
