OpenRAM to not clobber any files and allow simultaneous runs. If it
passes, the files are deleted. If it fails, you will see these files:
* _calibreDRC.rul_ is the DRC rule file.
* dc_runset is the command file for caliber.
* temp.gds is the layout

* temp.sp is the netlist

* test1.lvs.out is the standard output of the LVS command
* test1.lvs.results is the DRC results file
Depending on your DRC/LVS tools, there will also be:
* _calibreDRC.rul_ is the DRC rule file (Calibre)
* dc_runset is the command file (Calibre)
* extracted.sp (Calibre)
* run_lvs.sh is a Netgen script for LVS (Netgen)
* run_drc.sh is a Magic script for DRC (Magic)
* <topcell>.spice (Magic)
If DRC/LVS fails, the first thing is to check if it ran in the .out and
.err file. This shows the standard output and error output from
running DRC/LVS. If there is a setup problem it will be shown here.
If DRC/LVS runs, but doesn't pass, you then should look at the .results
file. If the DRC fails, it will typically show you the command that was used
to run caliber. It is something like this:
```
calibre -gui -drc /tmp/openram_mrg_28781_temp/drc_runset -batch 2>
/tmp/openram_mrg_28781_temp/test1.drc.err 1>
/tmp/openram_mrg_28781_temp/test1.drc.out
```
Or, if you are using Magic+Netgen, there will be a shell script run_drc.sh
and run_lvs.sh. To debug, you will need a layout viewer. I prefer to use glade
to run Calibre or Magic+Netgen.

on my Mac, but you can also use Calibre, Magic, etc.

3. Magic
Magic is only supported in SCMOS. You will need to install the MOSIS SCMOS rules
as well from: http://opencircuitdesign.com/magic/
and Magic from: http://opencircuitdesign.com/
When running DRC or extraction, OpenRAM will load the GDS file, save
the .mag files, and export an extracted netlist.
