Injecting a device into an existing net

ChrisEAS

Hi,

I am looking for a way to inject a voltage source (or a resistor etc.) into an existing net. My goal is to manipulate the voltage on the net, e.g. changing the threshold voltage of a MOSFET by injecting a vsource between gate an net connected to it. One solution I can think of is changing the schematic using Skill code - but I would like to avoid that. Another option is to modify the Spectre netlister, which basically works but feels too much of a hack to me.

Is there another, minimally intrusive way of achieving the same thing? E.g. some Spectre solution like alter statement or alike? Ideally I would like to create Spectre code which can be simply included into the existing and unchanged netlist. 

Thanks and best regards,

Christoph

    Christoph,
    you might also try looking at the 'nodeset' feature that Spectre has available? Not sure if this is what you are looking for, but I thought it was worth mentioning. Best regards,
    Lawrence.
