Function to get techfile via parameters

U can have the lib name in parameter like "my_lib"

after that: tf = techGetTechFile(ddGetObj("my_lib))

;

 Hi Brittoo,

Slayer's answer starts to answer your question, and I will add to it.  It will depend on what types of via devices you have in your techfile, but here is one example:

tf = techGetTechFile(ddGetObj("test"))

=> db:217181228 

techGetDeviceInClass(tf "syContact" "symbolic")

=> ("M1_P" "M1_N" "M1_POLY1" "M2_M1" "M3_M2") 

foreach(mapcar device techGetDeviceInClass(tf "syContact" "symbolic")

  techGetDeviceCParam(tf device "symbolic")

)

=> ((("layer2ImpEnc" 0.0) 

     ("layer2ImpLayer" nil) 

     ("layer1ImpEnc" 0.0) 

     ("layer1ImpLayer" nil) 

     ("encByLayer2" 0.6)

     ("encByLayer1" 0.6) 

     ("layer2" "metal1") 

     ("layer1" "diff") 

     ("viaLayer" "cont")

    ) 

    (("layer2ImpEnc" 0.0) 

     ("layer2ImpLayer" nil) 

     ("layer1ImpEnc" 0.0) 

     ("layer1ImpLayer" nil) 

     ("encByLayer2" 0.6)

     ("encByLayer1" 0.6) 

     ("layer2" "metal1") 

     ("layer1" "diff") 

     ("viaLayer" "cont")

    )

...

You can inspect what device classes there are using the techGetDeviceClass function:

 techGetDeviceClass(tf "" "symbolic")

=> ("ruleContact" "syRectPin" "syPin" "syContact" "syDepletion"

     "syEnhancement"

 )

Hopefully this will get you started.

Regards,

Lawrence.
