"""
|
||||
This is a DRC/LVS interface for calibre. It implements completely
|
||||
independently two functions: run_drc and run_lvs, that perform these
|
||||
independently three functions: run_drc, run_lvs, run_pex, that perform these
|
||||
functions in batch mode and will return true/false if the result
|
||||
passes. All of the setup (the rules, temp dirs, etc.) should be
|
||||
contained in this file. Replacing with another DRC/LVS tool involves
|
||||
rewriting this code to work properly. Porting to a new technology in
|
||||
Calibre means pointing the code to the proper DRC and LVS rule files.
|
||||
|
||||
A calibre DRC runset file contains, at the minimum, the following information:
|
||||
|
||||
*drcRulesFile: /mada/software/techfiles/FreePDK45/ncsu_basekit/techfile/calibre/calibreDRC.rul
|
||||
*drcRunDir: .
|
||||
*drcLayoutPaths: ./cell_6t.gds
|
||||
*drcLayoutPrimary: cell_6t
|
||||
*drcLayoutSystem: GDSII
|
||||
*drcResultsformat: ASCII
|
||||
*drcResultsFile: cell_6t.drc.results
|
||||
*drcSummaryFile: cell_6t.drc.summary
|
||||
*cmnFDILayerMapFile: ./layer.map
|
||||
*cmnFDIUseLayerMap: 1
|
||||
|
||||
This can be executed in "batch" mode with the following command:
|
||||
|
||||
calibre -gui -drc example_drc_runset -batch
|
||||
|
||||
To open the results, you can do this:
|
||||
|
||||
calibredrv cell_6t.gds
|
||||
Select Verification->Start RVE.
|
||||
Select the cell_6t.drc.results file.
|
||||
Click on the errors and they will highlight in the design layout viewer.
|
||||
|
||||
For LVS:
|
||||
|
||||
*lvsRulesFile: /mada/software/techfiles/FreePDK45/ncsu_basekit/techfile/calibre/calibreLVS.rul
|
||||
*lvsRunDir: .
|
||||
*lvsLayoutPaths: ./cell_6t.gds
|
||||
*lvsLayoutPrimary: cell_6t
|
||||
*lvsSourcePath: ./cell_6t.sp
|
||||
*lvsSourcePrimary: cell_6t
|
||||
*lvsSourceSystem: SPICE
|
||||
*lvsSpiceFile: extracted.sp
|
||||
*lvsPowerNames: vdd
|
||||
*lvsGroundNames: vss
|
||||
*lvsIgnorePorts: 1
|
||||
*lvsERCDatabase: cell_6t.erc.results
|
||||
*lvsERCSummaryFile: cell_6t.erc.summary
|
||||
*lvsReportFile: cell_6t.lvs.report
|
||||
*lvsMaskDBFile: cell_6t.maskdb
|
||||
*cmnFDILayerMapFile: ./layer.map
|
||||
*cmnFDIUseLayerMap: 1
|
||||
|
||||
To run and see results:
|
||||
|
||||
calibre -gui -lvs example_lvs_runset -batch
|
||||
more cell_6t.lvs.report
