1. subckt重复定义有两个解决方法:(1)给symbol做一个spectre view,这样netlist里面就不会有空的subckt定义;(2)在spectre option里面增加 duplicate_subckt=warning
duplicate_subckt=error
Specify whether duplicate subcircuit definitions are allowed. When set to warning or ignore, the simulator allows duplicate subcircuit definitions. However, it honors only the last subcircuit definition. Depending on
the value that is set, the simulator displays warning messages for the duplicate subcircuit definitions or does not display any message. When set to error, the simulator does not allow duplicate subcircuit definitions and displays an error message. Possible values are error, ignore and warning.
2. 通常数字综合的spice网表的电源和地是gloabal定义的节点,不会出现在subckt的port上,对应的symbol或许需要去掉电源和地的pin;然后使用global的电源,地。
