Connecting wires through SKILL IC 6.1.8

Use the schCreateWire() function - with "route" as the second argument and "full" as the third argument (the rest you can find from the documentation - including these two arguments). You'd then give the list of the start and end points and it will create the wiring between those points, routing as necessary.

Thanks for the quick answer,

I indeed found the function schCreateWire() in the docs, but I should have mentioned that it isn't the approach I need/want. The thing is that when working with multiple instances of a created CellName, I haven't been able to obtain the coordinates of each of the pins from the instances. Two questions arise if this is the correct approach:

Is there an equivalent function to schCreateWire() in which instead of using the coordinates, it uses either nets, pins or terminals?

If there isn't, what is the approach to obtain the coordinates for the pins of an instance?

I have found this approach how-to-find-the-coordinates-of-an-instance-s-pin in the forum, using:

$ cv = geGetWindowCellView( hiGetCurrentWindow( ) )

$ cv ~> instances ~> instTerms ~> term ~> pins

All the pins of the multiple instances point to the same object(i.e being unable to retrieve the coordinates for each pin of each instance). I am sorry if I was not able to explain myself properly, I am still learning skill. Thanks again.

If you can find the pin object for each terminal (using an approach like you've shown), then you can do this:

dbTransformPoint(centerBox(pin~>fig~>bBox) inst~>transform)

(where inst is the instance of the transistor above). So if you know it's terminal "D" you could do dbFindTermByName(inst~>master "D")~>pin~>fig - this is assuming there's a single pin and a single figure to find it.

There's no higher level function that does this for you, but it's quite simple to do.

I have been able to make it work. Thanks! I was unfamiliar with the function dbTransformPoint().

I will write the code in case someone stumbles upon this and needs it (suboptimal, probably).

cv = geGetWindowCellView( hiGetCurrentWindow( ) )

InstList = cv ~> instances

N0 = nth(0, InstList)

N1 = nth(1, InstList)

foreach( pin I0~>instTerms when( pin ~> name == "PIN_NAME" PIN_NAME0 =pin ~> term ~> pins))

foreach( pin I1~>instTerms when( pin ~> name == "PIN_NAME" PIN_NAME1=pin ~> term ~> pins))

A = dbTransformPoint(centerBox(car(PIN_NAME0)~>fig~>bBox) N0~>transform)

B = dbTransformPoint(centerBox(car(PIN_NAME1)~>fig~>bBox) N1~>transform)

schCreateWire( cv "route" "full" list(A B) 0 0 0)
