This is a DRC/LVS/PEX interface file for magic + netgen.
|
|
|
|
We include the tech file for SCN4M_SUBM in the tech directory,
|
|
that is included in OpenRAM during DRC.
|
|
You can use this interactively by appending the magic system path in
|
|
your .magicrc file
|
|
path sys /Users/mrg/openram/technology/scn3me_subm/tech
|
|
|
|
We require the version 30 Magic rules which allow via stacking.
|

We obtained this file from Qflow ( http://opencircuitdesign.com/qflow/index.html )

and include its appropriate license.
