SFGEN Command Line Syntax

The SFGEN program can be run from the command line. This enables a user to create scripts to run multiple layers or to have custom settings for different layers.

Displaying the Syntax

To see the syntax and options type at a command prompt:

Example 1

Assume we have an ODB++ file called input.tgz and we want to create 4 GDSII files using the ODB++ layers: l1, l2p, l3p and l4. The ODB++ step to process is called panel. Our DPI is 5080. No correction or annotation. The command line could look like this: (I've put in returns to make it fit on the page ...)

c:\wcad\sfgen64\sfgen64.exe -job:"E:\cad_files\input.tgz"
   -step:panel,l1 -outdir:"E:\cad_files\l1"
     -gds_layer:1 -gds_struct:TOP
        -thrnum:4 -arcres:45 -arcscag:2 -dpi:5080 -buffer:2048
c:\wcad\sfgen64\sfgen64.exe -job:"E:\cad_files\input.tgz"
   -step:panel,l2p -outdir:"E:\cad_files\l2p"
     -gds_layer:1 -gds_struct:TOP
        -thrnum:4 -arcres:45 -arcscag:2 -dpi:5080 -buffer:2048 

c:\wcad\sfgen64\sfgen64.exe -job:"E:\cad_files\input.tgz"
    -step:panel,l3p -outdir:"E:\cad_files\l3p"
      -gds_layer:1 -gds_struct:TOP
         -thrnum:4 -arcres:45 -arcscag:2 -dpi:5080 -buffer:2048 	

c:\wcad\sfgen64\sfgen64.exe -job:"E:\cad_files\input.tgz"
   -step:panel,l4 -outdir:"E:\cad_files\l4"
    -gds_layer:1 -gds_struct:TOP
        -thrnum:4 -arcres:45 -arcscag:2 -dpi:5080 -buffer:2048  

Each GDSII file would be in its own directory with data on GDSII layer 1 and a top structure named TOP.

Example 2 - Running SFGEN command line with Transformation

Assume we have a GDSII file called D001406_B_PRDL1_29_MP1433.003.gds and we want to run it from the command line with some transformation but no corrections on layer 29:20.
In this example, we are converting the input file with transformation - Mirror along X. No correction is used with this example. We use the -keep option to keep the log file and some other work related files. What we just did is creating a master GDSII file with the transformation you are interested in. You can next run all your corrections on this file with out wasting time running sfgen64.exe again.

C:\wcad\SFGEN64\sfgen64.exe -job:%CD%\D001406_B_PRDL1_29_MP1433.003.gds -outdir:%CD%\out\first.GDS -workdir:%CD%\work -struct:TOP -layers:+29:20 -log:%CD%\out\first.LOG -thrnum:4 -arcres:3.000000 -arcsag:0.200000 -jitter:1.000000 -dpi:25400.000000 -buffer:1024.000000 -rotate:0.000000,0.000000,0.000000 -mirror:x,0.000000,0.000000 -scale:1.000000,1.000000,0.000000,0.000000 -shift:0.000000,0.000000 -keep

Example 3 - Running the Correction Engine by itself

After running the input file through the transformation process using sfgen64.exe, we can now perform corrections on the file we mirrored in the previous step. The correction process is much faster than the first step. You should use this approach if you need to perform multiple corrections on the transformed file.

C:\wcad\SFGEN64\sffcorrection64.exe %CD%\OUT\first.gds  %CD%\cor.txt %CD%\out\corrected.GDS -tolerance:2.000000 -log:%CD%\work\corrected.LOG -silent

Example 4 - Running SFGEN64.exe with Transformation and Correction in one command

You can also run the sfgen64.exe with both transformation and correction in one command. Use this approach if you only need to do one type of correction.

C:\wcad\SFGEN64\sfgen64.exe -job:%CD%\D001406_B_PRDL1_29_MP1433.003.gds -outdir:%CD%\out\correction.GDS -workdir:%CD%\work -struct:TOP -layers:+29:20 -log:%CD%\out\correction.LOG -thrnum:4 -arcres:3.000000 -arcsag:0.200000 -jitter:1.000000 -dpi:25400.000000 -buffer:1024.000000 -rotate:0.000000,0.000000,0.000000 -mirror:x,0.000000,0.000000 -scale:1.000000,1.000000,0.000000,0.000000 -shift:0.000000,0.000000 -correction:%CD%\cor.txt -tolerance:2.000000
