Retrieving transistor location (x,y) on a placed design

Hello,

Lets say I have this small test design comprising of 15 transistors.
Lets not worry about its functionality (i.e. how the transistors are
connected). The circuit does something.

Now, I want to place and route this circuit/netlist. Lets say I use
Encounter for this (I don't know how to, but I will do it). So now
this design is placed and routed.

After this, shouldn't I be able to retrieve the following set of
information for every transistor:

I need these two pieces of information for every transistor in a
placed design for the next thing in my project.

What tool can do this? Or if not a tool, how can I extract this info
from which file after placement has been performed?

Please assume I know nothing (which is sort of true).

Thanks.
Shikhanshu.

If each transistor is an instance, you should be able to use this (untested, off
the top of my head, so don't blame me if it doesn't work) SKILL:

cv=geGetEditCellView()
fptr=outfile("./instreport.txt")
foreach(inst cv~>instances
fprintf(fptr "%s %s %d %d\n" inst~>name inst~>cellName
xCoord(inst~>xy) yCoord(inst~>xy)
)
)
close(fptr)

Routing transistors with Encounter is a rather unusual approach. It's not really
designed for that. And it's not designed for routing 15 transistors! That's
rather like using a sledgehammer to crack a very small nut. VCAR might be a more
appropriate router.
