I cannot use basic functions of skill in virtuoso (ex. nindex)

Hi YS,

(setq index2 nindex( name "<"))

You have extra parenthesis around. That is your mistake.

I am not sure what you want to do, but see below and example to reverse bits in a bus or translate it in a bracket like syntaxe.

name="bus<1:0>"
; nindex(name "<");=> 4
splitName=parseString(name "<:>");=> ("bus" "1" "0")
dbGetNameNumBit(name);=> 2
; check splitName length mayby
strcat(nth(0 splitName) "<" nth(2 splitName) ":" nth(1 splitName) ">");=> "bus<0:1>"
strcat(nth(0 splitName) "[" nth(2 splitName) ":" nth(1 splitName) "]");=> "bus[0:1]"

___ Hope it helps __

Actually I would like to do combine multiple instance which has same name

For example, there are instances which name is "I0<0>", "I0<1>", "I0<2>", "I0<3>"... "I0<12>" 

So, I want to combin them as "I0<12:0>".

That's why I need position of "<".

Of course, there is some way to do something like that. But, there is some error

SKILL: How to combine multiple instances of same master connected to the same net name in a design into an iterated instance

I want to combine all of the instance which has same name before bracket.

Also, if I can, I want to make that skill code that can do on same name instance and same net (ex, in<0>, in<1> ...) either.

Thanks.

You could use the code in this post: Generating Schematic pin list to collapse a list of names into a vector.
