Webthat you wish to short separated by a colon. In this example the nets are DGND:AGND:SGND. It is recommended that for each pin the primary net is first (i.e. pin 1 the NET_SHORT would equal SGND:AGND:DGND. You also need to ensure that you also have a PCB footprint defined for the netshort part. Webagnd有时被称为sgnd(信号接地层),是其他信号用作参照的接地连接,通常十分平静。该接地层包括调节输出电压所需的内部基准电压。软启动和使能电压也以agnd连接为参照。 关于这两种接地连接的处理,有两种不同的技术观点,因此专家的意见也产生了分歧。 Web105 Main Street, P.O.
