How to get VIAS name for a particular technology ?

Amar Kumar

Hello,

 

To get all the VIAS name for a technology , I am using this :

techID~>viaDefs~>name

The above statement is giving me all the VIAS form the technolog y, but  I want only the vias which can be used in layout.

Ex: when you call the function "leHiCreateVia()" in layout window,a GUI opens.In that GUI list of VIAS are there , which user can select and put in the layout .

So through skill , how can I get those vias name.

OR from list (techID~>viaDefs~>name) , how can I filter the original VIAS.

Please suggest me,

 

Thanks in advance,

Amar

  • Hi Amar,

    cvId=geGetEditCellView()
    cgName=cstGetDefaultConstraintGroupName(cvId "Via")
    split=parseString(cgName ":")
    cgId=if(car(split)=="dsn" then
        cstFindConstraintGroupIn(cvId cadr(split))
      else
        cstFindConstraintGroupIn(techGetTechFile(cvId) cgName)
      )
    validVias=cstFindFirstConstraint(cgId "validVias")->value

    This gets the current constraint group name (as specified on the Editor Options) for Vias, and then looks up that constraint group, and then looks for the "validVias" constraint and retrieves the value.
