Create multiple Instances with multiple variables

Hi Daniel,

I don't understand what you are trying to achieve...

If you want to create a bus current source, you probably have specific instances available to do so

(or you could generate stimulis, maybe this Cadence Support post could help you SKILL: How to generate bit-blasted stimuli and connect them to the bus in schematic)

If you want to create different sources and merge them as a bus signal I don't really get why you would do that...

To me it would be more meaningful to make them different signals

If you really want to generate several current sources as instances following a given pattern and name them as bused instances, you could still create a custom SKILL script to do so but I don't believe you can have a parallelized instance having different parameters (except connectivity)

Hope this help

Cheers,

Aurélien

Hi Daniel,

Bellow is an example function to generate a set of vdc.

Here is an example step by step

cv=geGetWindowCellView();=> db:0x16a9c89a ;<= GET the identifier of the current cellView (opened empty shematic before)
v=dbCreateInstByMasterName(cv "analogLib" "idc" "symbol" nil 0:0 "R0");=> example one
v=dbCreateInstByMasterName(cv "analogLib" "idc" "symbol" sprintf(nil "idc<%d>" 0) 0+1:0 "R0");=> example two

;; study cdfgData=(cdfGetInstCDF css())~>parameters~>value
foreach(mapcar p (cdfGetInstCDF v)~>parameters list(p~>name p~>value))
;=> (("noisefile" "") ("FNpairs" 0) ("F1" "") ("N1" "") ("F2" "") ("N2" "") ("F3" "") ("N3" "") ("F4" "") ("N4" "") ("F5" "") ("N5" "") ("F6" "") ("N6" "") ("F7" "") ("N7" "") ("F8" "") ("N8" "") ("F9" "") ("N9" "") ("F10" "") ("N10" "") ("idc" "") ("acm" "") ("acp" "") ("m" "") ("tc1" "") ("tc2" "") ("tnom" "") ("xfm" "") ("pacm" "") ("pacp" "") ("srcType" "dc"))
param=cdfFindParamByName( cdfGetInstCDF(v) "idc");=> cdf:0x0x24ed2a70 <= GET THE PARAMETER YOU WANT. HERE IT IS "idc"
param~>value="i_in0" ;#<= affect the value of the variable of the current.
param~>value=sprintf(nil "i_in%d" 0) ;<= second example to change 0 to your parameter

The parameter you want to change is named "idc", i do not know how to acces to it except by using cdfFindParamByName and cdfGetInstCDF functions.

Although if you understand the code of my function vdcGen, you can change vdc with idc, and it will create a set of idc with one parameter shifted every bits to get a kind of Digital to Analog DAC current source.

Hope it helps,
