schCreateWire + floating nets issue

[bu-bu]

Hello,

Please i need your help

I have written a skill script to change the symbol of some transistors
in my schematic.
But i can not just replace the headers, since the bulk of the new
transistor is at different location.

So i wanted to create a small piece of wire between the existing wire
(which does not connect anymore the bulk ) and the new terminal.

I used schCreateWire for that.
schCreateWire( cv "route" "full" list(list(px1 py1) list(px2 py2)) 0
0 0 )

(i just put this part of my code since the rest is just calculation of
my points p1 and p2)

when i probe my net, all look fine. The net and the terminal are
blinking ^^v

Then, when i check & save my schematic, i have the following warning:

Warning: Floating net "MyNet" at (3..35 1.5250)

and the returned location is the perfect center of my newly connected
terminal.

I don't understand why . Could someone help me please ?

Thanks,

bubu

I don't understand why either from your description - very hard to tell without
seeing it. Perhaps you could contact your local Cadence customer support for
assistance?

Hi Andrew-san,

Thanks a lot for your reply. Unfortunaltely, my local Cadence Customer
support is off this week It was "Memorial day" holiday, then the
full week was off for them.

But i have another clue: When i try to open a cell of my PDK library,
i have the following warnings:

....
\w *WARNING* Parameter 'srs' already exists.
\w *WARNING* Parameter 'prl' already exists.
\w *WARNING* Parameter 'HardCons' already exists.
\w *WARNING* Parameter 'ResCalc' already exists.
\w *WARNING* Parameter 'macroArgumentStyle' already exists.
\o -- tsmcN90lo.rppoly_dis.cdfe
\w *WARNING* Parameter 'model' already exists.
\w *WARNING* Parameter 'macro' already exists.
\w *WARNING* Parameter 'description' already exists.
\w *WARNING* Parameter 'res' already exists.
....

Looks like i have problems with my CDF ? And maybe that's why the bulk
of the transistors are not recognized ?

Thanks,

bubu

Sounds very odd - it sounds as if something is updating the CDF on the fly.
Perhaps that's why, but it seems unlikely...
