Internally, the extraction functions always take these devices as shorted, and they are otherwise ignored. When generating a SPICE file during simulation or with other commands in the side menu, these devices are included as normal devices. The present state of the netlist data structures will reflect the state of the last operation.
Setting this flag will cause rebuilding of the data structures to the requested state if necessary when one of the functions in this section is called. This persists until some other function, such as an extraction or SPICE listing function is called, at which time the internal state of the flag may change. Thus, this function may need to be called repeatedly ahead of the functions in this section.
The return value is the previous value of the internal flag.
