skill script for counting NMOS in a layout

[aannam]

gegetcellviewwindow() skill

Hi all,

I have just started to learn skill scripting. I would like to find the number of NMOS and PMOS in a layout using scripting. Can anyone help me to get rid of this problem?????

hi all,

I have found the way for counting the number of nmos and pmos in a layout when it is not flattened. But i want to know the procedure for the same when the layout is flattened. Since my layout is flattened i couldn't discriminate layers and also i couldn't find the instances. Please help me to find the solution for that

As far my knowledge, we can't determine the transistors from layout. You can extract all the info regarding no.of transistor & each transistor sizes from a GDS file. Others can say their views.. I tried to measure the particular transistor size & no.of fingers from layout, I couldn't succeed in that..

I don't know how to do it in skill, but it works well - independently of the hierarchy depth, if you select "current to bottom" - with the Edit -> Search (S) function from the Virtuoso Layout Menu, s. the image below.

The corresponding code (in CDS.log) is:
leSearchForm->criteriaScrollView->value1->value = "yourTransistorCellName"
_hiFormApplyCB(leSearchForm)

Hi all,

I got the script for the question which i asked in this forum. Here it is. If you find some other way to do the same please do reply in this forum


clv=dbOpenCellViewByType("Training" "ORmod" "layout" "" "r")
win=geGetCellViewWindow(clv)
p = outfile("/home/ams_trng6/skill/r.out" "w")
pout=leLayerAnd( clv list("PO" "drawing") list("OD" "drawing") list("M1" "drawing") )
declare( pmos[length(pout~>bBox)])
declare( v[length(pout~>bBox)])
b=0
foreach(a pout~>bBox
v=a
b=b+1
)
for(i 0 length(pout~>bBox)-1
pmos=cadadr(v)-cadar(v)
)
for(c 0 length(pout~>bBox)/2-1
fprintf(p "The pmos %d width are %L\n" c+1 pmos[2*c+1])
fprintf(p "The nmos %d width are %L\n" c+1 pmos[2*c])
)
foreach(shape pout
geSelectFig( shape)
geDeleteSelSet(win)
)
close(p)
