I need select via arrays of different column/rows so I can change the
spacing and count due to a wide
metal rule violation. The search that works is for via by name which
wont allow me to select specific
configurations. Does anyone have a skill routine or something so I
can selective select the arrays?
Thanks

Rick,
Which version are you using? vias are represented very differently in IC5141 and
IC61X, so it's important to know that before anyone may be able to help.

Andrew.
HI Andrew - didnt know that.....Im still using IC51

Hi,
I've got a code for ICFB5.141 to select only vias in the layout top
cell:
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
cvID = hiGetCurrentWindow()~>cellView
tfID = techGetTechFile(cvID)
CutDevs = techGetDeviceInClass(tfID "syContact"
"symbolic") /*get list of contacts from techfile*/
SEL > > > list() /
*initialize*/
foreach( INST
cvID~>instances /
*get list of instances*/
when( member(INST~>cellName
CutDevs) /*check which are
vias*/
SEL = cons( INST SEL )
) ;when
) ;foreach
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
This code is quite laborious at it checks each instance in the layout..
Mind you, the techfile has to have definition of symContactDevice() to
work and the vias have to be those created using "Create > contact"
command (or the 'o' default Virtuoso bindkey).
Now, the next step is to differentiate between which vias have column/
row properties greater than a certain value e.g. row > 4 or column
4.
I'll get to that part in a while since the only way I can see is by
accessing "INST ~> prop ~> value" and "INST ~> prop ~> name"
which seems messy. I'll get to this later.
Anyone got any other method?
Best regards,

OK, the next half of the code is as follows:
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
RowCol_FLAG = 4
SEL_2 = list()
foreach( INST SEL
CHECK_CR = nil
when( member("row" INST~>prop~>name)
RowPos = length(INST~>prop) - length(member("row"
INST~>prop~>name))
RowVal = nth(RowPos INST~>prop~>value)
when( RowVal >= RowCol_FLAG
CHECK_CR = 1
) ;when
) ;when
when( member("column" INST~>prop~>name) && !CHECK_CR
ColPos = length(INST~>prop) - length(member("column"
INST~>prop~>name))
ColVal = nth(ColPos INST~>prop~>value)
when( ColVal >= RowCol_FLAG
CHECK_CR = 1
) ;when
) ;when
when(CHECK_CR SEL_2 = cons( INST SEL_2) ) ;when
) ;foreach
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Pretty messy, huh?
But that's what I have at the moment.
For the list of vias that was targeted, print variable SEL_2.
Since my comments aren't put in properly, I'll explain here.
RowCol_FLAG :- minimum no. of rows/columns accepted to select
CHECK_CR :- marks if the current via needs to be selected or not
RowPos/ColPos :- since position of properties "row" & "column" vary in
the 'INST~>prop~>name' list, a marker is needed so that the value
from 'INST~>prop~>value' is according to 'INST~>prop~>name'.
RowVal/ColVal :- value for property "row" & "column" respectively
Best regards,

WOW!!!! can I just append the top half with the second half?
Thanks for all of your effort!!!!
