Aliasing net or shorting net of an extracted view

I have no idea what you're asking. n2port doesn't have a "GR" terminal - I just can't make sense of your question.

A picture might help?

Andrew

Thanks for the reply Andrew.

Here is the image of the n2port where the 3rd terminal is a GR net.

I wish to connect this to schematic ground net. As of now I am using a small resistor from analogLib to do this but is there a way to short these nets ?

Why don't you just wire them together (and not give the nets two different names)? If you really want to give them two different names, you could use the "patch" component from the basic library (or Create->Patchcord) to alias the two nets.

There must something I'm missing here?

Thanks Andrew, the extracted view was generated from the layout with ground netname GR instead of gr (schematic ground net) so the n2port created after extraction has GR net in i.

So GR net is coming automatically after extracted view is invoked.

I can delete GR net and connect the 3rd terminal of n2port to gr directly but not sure if that will impact the functionality of the n2port s-parameter which was originally created with GR net ?

The s-parameter file has no node names - it just has ports (two ports in this case) - the node names are irrelevant. So you can safely change this without impacting the functionality (inserting the 1ohm resistor would however have a small impact).

Thanks Andrew, this is helpful information.

Hi All,

I am facing an issue in that the layout I have received is not in sync with the schematic in terms of the pin names and net names. for example the layout has pin name RFIN whereas the schematic has rfin so all the nets and pins in the layout have been put in capital letters.

Is there an easy way I can rename the nets and pins in the layout to be the same as in the schematic ?

Due to this pin name difference I am unable to generate the extracted view  post s-parameter simulation of the layout.

Any workarounds will be great help.

thanks

Presumably you're not using Layout XL? That said, if you did and did update Components and Nets, it would create new pins and you'd have to move them into place.

It would probably be easiest to write some SKILL code to fix this, because it's a very specific requirement - that code would then be adapted to fix whatever was wrong. I suggest you contact customer support, because writing some code based on an incomplete description of possible mismatches is not going to be very helpful - it would be better to see this. If it's just a matter of converting the pin names to lower case, something like this may work (adapt to suit your needs):

cv=geGetEditCellView()
foreach(term cv~>terminals
  term~>name=lowerCase(term~>name)
  ; fix any attached labels
  foreach(pin term~>pins
    foreach(pinFig pin~>figs
      foreach(child pinFig~>children
        when(child~>objType=="label"
          child~>theLabel=lowerCase(child~>theLabel)
        )
      )
    )
  )
)

Thanks Andrew I will check this out , I am using Layout EXL mostly.
