I am trying to create a rod path. Which should create a stack of top and its bottom layer with vias. for ex M2 Via1 M1. So that the vias should get automatically streached when i streach the path.

Thanks

Hi Andrew,

I was trying to implement this rodCreatepath function. In that i am facing problem in subrect lsit. When i tried to implement
width >=0.28 in subRect list . its only drawing the list 2 elements not the list1 elements. Can i do this in some other possible way.
(w >=0.28
list(
?layer list("VIA1" "drawing")
?width 0.05
?length 0.05
?beginOffset -0.05
?endOffset -0.05
?beginSegOffset 0
?endSegOffset 0
;?space 0.08
?sep 0.075
?choppable t
?justification "center"
?gap "distribute"
)
list(
?layer list("VIA1" "drawing")
?width 0.05
?length 0.05
?beginOffset -0.05
?endOffset -0.05
?beginSegOffset 0
?endSegOffset 0
?space 0.08
?sep -0.065
?choppable t
?justification "center"
?gap "distribute"
)
)
Thanks

Neeraj,

Please post the entire call to rodCreatePath, not just part of it - that will make it much easier to see what you're doing in your code. It's surprising how often problems lay somewhere different to where people think... (In general, not just with this function).

Regards,

Andrew=

hiSetBindKey("Layout" "Ctrl<key>8" "metalStackUP()")

when i am trying to create 2 rows of via for increased width its just laying out only one row of via.

Neeraj,
I was right - the problem is outside the code you originally posted...
Most functions in SKILL return the last thing executed. The cond() function is the same - it is of this form:
cond(
(condExpr1 expr11 expr12 expr13)
(condExpr2 expr21 expr22 expr23)
...
)
It tries each conditional expression (e.g. condExpr1) and if non-nil, the rest of that branch is executed. It will successively evaluate exprN1, exprN2, exprN3 and so on, and the return value will be the last expression on that branch (e.g. expr13 or expr23). In your case, the condition branch for w>=0.28 has two expressions, the two list() calls - and the return value will be the second of these.
Since you want it to be a list of lists, the answer is to alter the code have the cond() one level up, so for example:

?subRect

cond(

(w <=0.27

   list(
                                                     list(

?layer list("VIA1" "drawing")
?width 0.05
?length 0.05
?beginOffset -0.05
?endOffset -0.05
?beginSegOffset 0
?endSegOffset 0
;?space 0
?sep 0
?choppable t
?justification "center"
;?gap 0.08
;?connectivity "none"

)
                                                       )
)

(w >=0.28 list(

list(

?layer list("VIA1" "drawing")
?width 0.05
?length 0.05
?beginOffset -0.05
?endOffset -0.05
?beginSegOffset 0
?endSegOffset 0
?space 0.08
?sep 0.075
?choppable t
?justification "center"
?gap "distribute"

)

list(

?layer list("VIA1" "drawing")
?width 0.05
?length 0.05
?beginOffset -0.05
?endOffset -0.05
?beginSegOffset 0
?endSegOffset 0
?space 0.08
?sep -0.065
?choppable t
?justification "center"
?gap "distribute"


)
)
)
)

Your brackets didn't match properly in your code, and it looked as if you'd tried to get the second branch to return a list of lists, but since you had a list() around the cond, that wouldn't have been correct either.

BTW, you shouldn't use css() in your code. This is a private SKILL function and not documented. It might get changed or removed at some point in the future. So use car(geGetSelSet()) instead.

Regards,

Andrew
