How do I set valid layers on bootup of Cadence Virtuoso XL?

dietSprunk

I would like to set my own custom list of default valid layers on bootup of Cadence Virtuoso XL. (IC6.1 and IC20)

I never have write access to the tech file, so changing that is never an option.

I want to override locally which layers are valid and which layers are not valid, similar to how the .drf overrides layer colors, outlines, stipples, etc.  For example, the tech file on my last project dictated that TEXT DRAWING layer was not valid and I needed to set it valid manually in the LSW Palette window.  There were many other layers like this as well, that I used on a daily basis.  This is annoying and a real waste of time. 

Is there a file I can export (similar to the .drf) that can save all of my valid layer preferences and then be loaded inside my .cdsinit?

***Important note: I am not asking how to create a custom layer set list here.***

    You could just change the valid attribute of the layer in memory using SKILL. For example something like this:

    let((tf lp)
  tf=techOpenTechFile("gpdk045" "r")
  foreach(layer list("y0" "y1" "y2" "y3" "y4" "y5")
    lp=techGetLP(tf list(layer "drawing"))
    lp~>valid=t
  )
  t
)
