Change path width with bindkey

Try this method:

procedure(pathWid(widBool)

grid = techGetMfgGridResolution(techGetTechFile(geGetEditCellView()))

wid = obj~>width

foreach(obj geGetSelSet()

when(member(obj~>objType '("path" pathSeg")

if(widBool then

obj~>width = wid+2*grid

else   obj~>width = max(2*grid wid-2*grid))

)

)

sorry of there is some syntax error
just wrote it quick

another method  you might want to try than stepping by grid is to step by width

define width (0.010 0.020 0.030 0.040)

if 0.010 step to 0.020 and 0.020 to 0.030 etc...

If you need the script written better let me know

Hello Paul,

thank you for your reply.

I tried your procedure but nothing happens. I think the problem is, that the function geGetSelSet() returns "nil" when i direktly draw a path because the path isn't selected. So I need to get the object id from the path i'm currently creating. Do you have any hints for me?

You do not need to toggle the visibility of the form since it is already defined. You can use the rest of your bindkey to change the value.

hiSetBindKey("Layout" "Alt<Btn4Down>" "le0WireForm->wireWidth->value=le0WireForm->wireWidth->value+0.01")

Cadence has their own commands to do the same thing:

  hiSetBindKey("Layout"    "CtrlShift<Btn4Down>" "weScaleMagnifierOrIncreaseWidth()")
  hiSetBindKey("Layout"    "CtrlShift<Btn5Down>" "weScaleMagnifierOrDecreaseWidth()")

If those commands don't exist, an older version of Cadence had:

  hiSetBindKey("Layout"    "CtrlShift<Btn4Down>" "_leWireCmdMagnifierOrIncreaseWidth()")
  hiSetBindKey("Layout"    "CtrlShift<Btn5Down>" "_leWireCmdMagnifierOrDecreaseWidth()")

Hello Derek,

thank you very much for your reply. This function "weScaleMagnifierOrIncreaseWidth" is exactly what i was looking for. There is only one little problem. These functions have predefined values for changing the path with. (0.02 µm) I would like to change the path in smaller steps. Is there an variable which i need to set or is this delta width a fix parameter in the function?

The other function: "le0WireForm->wireWidth->value=le0WireForm->wireWidth->value+0.01" can do this job but has two disadvantages:
- the window is not directly updated -> only when i'm moving the path i currently create the change in width is visible...
- in the other function the new width is diplayed, here not

Regards

Flo,

These functions (which are bound by default to shift-ctrl mouse wheel) increase or decrease to the next valid width - so that's typically in steps of double the manufacturing grid.

If these don't behave the way you want, then please contact customer support - maybe we can add an optional argument to define the step size? The key thing is that these cause the wire editor to be updated and the appropriate interactive refresh to be performed.

Regards,

Andrew.

Flo,

you can change the step by setting the following variable:

envSetVal("layout" "_weMfgGridWidthIncrement" 'int 2)

where 2 is a default value.
