Hi all,
A very stupid issue. With a new technology i use i can not complete a
routing without generating 1000000 errors. The errors are DRC errors on
each metal layers. I assume it is due to the via shapes that are
rectangulars (not squared). So my question is: How are calculated the
GCELLS for the routing?
In my lef file i have:
WIDTH 0.1
SPACING 0.1
PITCH 0.3
OFFSET 0.15
it seems that the channels used by SE make 0.2um instead of 0.3um.
So the second question is :
The GCELL is built with WIDTH + SPACING or with PITCH?
On my opinion, it should be PITCH.
Thanks in advance.
