@Tim Edwards Hi, how can I obtain a high-resolution image of a layout? I want to use it for a journal paper. Thanks in advance!

@Yusuke Sakemi: For a full-chip layout, nothing beats the PNM plot routine written for Magic by Rajit Manohar. In magic, expand the layout and then do

plot pnm <filename> <width>

For a full-chip layout, a width of 1000 usually makes a nice output. Since PNM files are not compressed, you probably want to use ImageMagick's "convert" command to convert the output:

convert <filename>.pnm <filename>.png

Thank you very much. The plot command worked nicely! I found that before that command, flattenning the layout was necessary to properly visualize the layout.

flatten -nolabel -noport <cellname>
