<h1>Convert an DFII technology file into KLayout format</h1>
7+
8+
Start the Cadence icfb tool and call the "Technology Tool Box". Then press the "Dump"
9+
button in the tool box. In the "Technology Library" pulldown select the OA technology library
10+
you want to dump. Please make sure that that you only switch the "layerDefinitions" toggle
11+
to "On". Fill out the textbox with name of the output ASCII technology file. Then push the "OK"
12+
button to write out the technology file.
13+
14+
<p>
15+
<img src="df2_NCSU_Techlib_tsmc02_laydefs.gif">
16+
<p>
17+
Then locate the current "display.drf" file in the virtuoso run directory. It coIf not found then
18+
please take a look at the technology directory, which should contain the original version of
19+
the display.drf file. The display.drf file contains color and layer visibility and style
20+
defintions, fill pattern and line style information.
21+
22+
As third item we need a copy of the OpenAccess stream layer map file. It should reside in the
23+
technology library and is usually called "streamin.layermap". It will contain a mapping
24+
between OA layer/OA purpose to GDSII layer number and GDSII datatype. Here is an exmaple:
25+
<p>
26+

27+
# ------------- --------------------- -----------
