Obtaining List of All Etch Layers in a Design

Hi,

You can use axlGetXSection() which will give you everything you ask for plus more.

Please see attached picture of running this command in the 'Skill development' window.

Hi,

I forgot to mention that if you're only looking for the name of the etch layers you could use

my_layers = axlGetParam("paramLayerGroup:etch")

This will give you a list of all the etch layers.

You could then cycle through these using eg.

foreach(layer my_layers->groupMembers
  layerparams = axlLayerGet(strcat("ETCH/" layer))
    if(layerparams->type=="PLANE" && layerparams->drcPhotoType=="negative" then
     pm = 0 ; plot mode negative
  else
   pm = 1 ; plot mode positive
  ) 

There are many practical uses of this, if you could be more specific about what you wan't there may be an even easier or better way.

Have fun

Hi.  I want revive this thread a little, to see if I can get a wee bit of help; my Skill ability is minor.  What I would like to know is if there is a way to do something like this, which I am currently doing with a script, tied to my PageUp button key.  It requires that I edit the script to include only conductive etch layers, which changes with every stackup:

# Allegro script

settoggle layerchange 1 3 5 6 8 10
setwindow form.mini
FORM vf_vis all_all_visible NO
FORM vf_vis $layerchange all_colorvisible YES
setwindow pcb
echo "Layer " $layerchange

I can see that I can get a list of all the layers in Skill, but how would I get only the conductive layers?  Do I need to filter them?  If so, how?  In addition, I do this with PageDown.  For me, this is such a cool way to quickly traverse all the routing layers, making it easy to see how to route out of difficult areas.  Turbo charging it with Skill would be cool.

First, it is wise not to use script files for changing the visibility. You can't do this fast since the window is always redrawing. 

Better use skill to change visibility. Look at axlVisibleGet and axlVisibleSet in the ..\SPB_16.6\doc\algroskill\algroskill.pdf help file. 

edit: With axlVisibleLayer you can set a layer visible or invisible.

To get all etch layers: axlGetParam("paramLayerGroup:ETCH")->groupMembers

axlSubclassRoute returns all etch subclasses.
