in magic is there a simple way to get the size of a cell boundary (for scripting purposes)?

You mean size of the cell? Just take your cursor above the selection and press b. The details should be visible in the command shell.

This is hypothetically an auto-generated cell going straight into another tool that needs to know it's size. I am doing it by looking at the original generation parameters atm but was wondering if there's a shortcut

@User might have an answer.

@User: If it's an abutment box like is used for standard cells, then it is set as a property of the cell called FIXED_BBOX and can be obtained with

property FIXED_BBOX

. Otherwise, you can get the geometrical bounds using

load <cell>;  select top cell; box values

. The returned value will be in internal database units. That may be sufficient for scripting purposes; if not, and you need units in, say, microns, then multiply all the box values by the value returned by

cif scale out

(which is the conversion scalefactor between internal units and microns).

thank you 🙂

In a script you want to do, e.g.,

set bbox [box values]

, something like this should work:

set scf [cif scale out]
select top cell
set bbox [box values]
set llx [expr [lindex $bbox 0] * $scf]
set lly [expr [lindex $bbox 1] * $scf]
set urx [expr [lindex $bbox 2] * $scf]
set ury [expr [lindex $bbox 3] * $scf]

I'm trying to use the

load <cell>;  select top cell; box values

method

The problem is that

box values

does not print to stdout; it returns a result which is a list. The behavior of the console is to echo all results, but this is console behavior, not Tcl/Tk behavior. So if you want the result printed you will need to do

puts stdout [box values]

.

ahh right, I will give that a shot
