EEC 116 - Printing Designs
Screen Snapshots (recommended for layout)
Printing using the other methods using a grayscale printer
is troublesome since they typically come out with little to no
contrast. Using a screenshot to capture the textures you see
inside Magic is usually the way to go. This also covers how to
remove the ugly gray background and make the printouts easier to
- Open up GIMP from Applications -> Graphics -> The
GIMP on the lab computers.
- Go to File -> Acquire -> Screenshot in the
- Use the tool to capture a screen shot of the window. You
probably should maximize the window first and Zoom to Fit your
layout. Default key is z.
- Use the selection tools to crop the shot as needed. The crop
tool is under Image -> Crop Image.
- Use the Select regions by color tool in GIMP (default
shortcut is Shift+O) to select the gray background color.
- Use the Fill Bucket (Shift+B) and set the
Affected Area to Fill whole selection. Make
sure to fill using the color white.
- Save and print.
Printing from Magic
- In magic with the layout window selected, press s
while pointing the cursor outside your cell to select the entire
cell. You can also use the box to select
just the section of your design you want to print.
- In the magic text entry window type
'plot postscript file.eps'.
- In the terminal window type
'lpr-magic file.eps'. This will default to the printer
in room 2107 but it can be changed by supplying a new destination
as the second argument to lpr-magic, such as
'lpr-magic file.eps LJ2110'.
- To convert the EPS file to PDF, open a terminal window and
type 'epstopdf file.eps'.
- If the postscript files are too large for your account
quota, print the file directly to the /tmp directory, which
is writable by all users, has no quota, and is 1 GB on
the ECE machines in 2107. Then either convert
to pdf, or for very large files, convert to high-quality
jpeg using "gimp".
In some cases, there are problems with some layers and
features not showing up very well--usually nwell, pwell,
and certain vias. The problem seems to be coming in the
conversion from .ps to .pdf. Two alternate workarounds are
to print directly with .ps, or using "Print Screen" (see
Printing from IRSIM
- In the analyzer window select 'Print -> File'
and type in a filename such as file.ps.
- In a terminal window type 'lpr-irsim file.ps'.
This will default to the printer in room 2107 but it can be
changed by supplying a new destination as the second argument
to lpr-irsim, such as 'lpr-irsim file.ps LJ2110'.
- To convert the PS file to PDF, open a terminal window and
type 'ps2pdf file.ps file.pdf'.
- Very large print files. If this happens, try turning off
some layers with "see no metal6", for example.
