Help on create VIA in 6.1.4 version

Yes, it's because you're passing a quoted list to the function. The quote operator means that the list is taken literally, with no evaluation. So the n in the list is passed as n not 6. Obviously it's not expecting the symbol n there, so it fails.

Another thing - you don't really need to assign the value to a variable (the viaParams= bit) unless you're going to use it later - but maybe that was done for a good reason.

Anyway, what you need is either:

dbCreateVia(pcCellView viaid 0:-1 "R0" 
viaParams=list(list("cutRows" n) 
'("cutColumns" 1) 
'("cutSpacing" (0.1 0.1)) ; space via
'("imp1Enc" (26.07 26.07)) ;PP 
'("imp2Enc" (0.07 0.07)) ;PDK layer 
'("layer1Enc" (0.02 0.02)) 
'("layer2Enc" (0 0.03))
))

or:

dbCreateVia(pcCellView viaid 0:-1 "R0" 
viaParams=`(("cutRows" ,n) 
("cutColumns" 1) 
("cutSpacing" (0.1 0.1)) ; space via
("imp1Enc" (26.07 26.07)) ;PP 
("imp2Enc" (0.07 0.07)) ;PDK layer 
("layer1Enc" (0.02 0.02)) 
("layer2Enc" (0 0.03))
))

This second form is a neat feature of SKILL - a special kind of quoted list. If you use the backquote instead of the normal single quote, then the list is taken literally except where a subexpression is preceded by a comma. Those preceded by commas get evaluated. It's actually a macro that expands into lists of lists etc, but it's a lot more succinct to type!

If you look at viaParams after calling this, you'd see the value 6 where the ,n was. Note there's also another form that can be used inside a backquoted list - ,@ - but I'm not going to cover that here since you don't need it (this is for splicing in lists).
