reg cadence schematic -- geometric information

[lokesh]

Hi all,
I'm trying to view the geometric information of the cadence schematic.
The following is what I wish to see.
Lets consider a standard CMOS inverter schematic in cadence.
From this schematic what I want to view is, the (x,y) location of the
instance PMOS and NMOS. And geometric information about the line that
connects the PMOS and NMOS drains together(whether there is only a
single connection/net between the drains or it is branching out to
some output node).
In this regard,
Which is the database file that I have to refer for getting the above
information.

Thanks and regards,
Lokesh

Hi,

try "dbWriteSkill"
Have the cellview open:
cv=geGetEditCellView()
dbWriteSkill(cv "outfile" "a" version)
; set to version to "6.1" or "5.0" , depending on your installation
;that will create the "outfile" where you find all the geometric
informations

Regards,
Marc

Thanks Mark..
That was the exact stuff I was looking for.
cheers,
