Blockage layers info

psill000

How do I get the list of blockage layers from the techfile, library or cellview.

Is this correct way to toggle the visiblity and selectablity by using the commans below.

pteSetVisible("Blockages;Routing Blockage;M1" nil "Objects")

pteSetSelectable("Blockages;Routing Blockage;M1" nil "Objects")

Would the pin blockage be about the same on get the list and toggling the visiblity and selectablity?

    Hi Paul,

    To get a list of the layer-purpose pairs that are of type blockage, one way is as follows:

    tf = techGetTechFile(ddGetObj("myTechLibName"))
blockageLPs = setof(lp tf~>lps lp~>purpose=="blockage")
=> (db:0x18e15d68 db:0x18e15dd0 db:0x18e15e38 db:0x18e15ea0 db:0x18e15f08
     db:0x18e15f70 db:0x18e15fd8 db:0x18e16040 db:0x18e160a8 db:0x18e16110
     db:0x18e2c680 db:0x18e2c6d8
 )

blockageLPs~>name
=> ("Metal1" "Via1" "Metal2" "Via2" "Metal3"
     "Via3" "Metal4" "Via4" "Metal5" "Via5"
     "Metal6" "Cont"
 )

    This is a list of LP objects, i.e. each item on the list is a layer-purpose pair object in the technology file. From this then you know which layers have blockages defined for them (as layer-purpose pairs in the techfile, I'm not talking about which layer blockages might exist in a design).  I haven't looked into your second question - the commands look about right but I've not tested. Not sure what you mean about "the pin blockage", sorry.

    Hope this helps!

    Lawrence.
