I am able to create contact in IC5141 version using leCreateContact command. But this is not works in 614 version. Please let me know create a VIA in layout in 614 version.
leHiCreateVia or dbCreateVia.
In reply to Andrew Beckett:
What is d_viaDefId in dbCreateVia? I got below error for dbCreateVia command.
x=y=0dbCreateVia( geGetEditCellView() "M2_M1_S" list(x y) "R0" list( list("cutRows" 2) ;row list("cutColumns" 4) ;column list("cutSpacing" list(x y)) ; cut spacing for x and y list("layer1Enc" list(x y)) ; enclosure for layer1 list("layer2Enc" list(x y)) ; enclosure for layer2 list("cutWidth" 0.2) ; cut width list("cutHeight" 0.4) ;cut height list("originOffset" list(x y))) ; j
*Error* dbCreateVia: argument #2 should be a database object (type template = "ddltg") - "M2_M1_S"
M2_M1_S is my via name.
In reply to Sarvani:
Use techFindViaDefByName() to retrieve that.
I have a problem with this subject. My code is below:
viaid=techFindViaDefByName(tfId "VM3_M4") n =6 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)) ))
It doesn't work. And Cadence give a warrning :
*WARNING* (DB-270576): Invalid cutRows(0)
At line 4, If I use n is 6 (code is viaParams='(("cutRows" 6) ....) it's working.
Do you have any ideal ? I want to use a parameter (n) instead a number (6) . Thank
In reply to Nguyen Dinh Thuc:
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))))
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).
