Extraction of nfet and pfet

In my divaEXT.rul is written:

(drcExtractRules
(bkgnd = (geomBkgnd))
(pdiff = (geomOr "pdiff"))
(ndiff = (geomOr "ndiff"))
(pwell = (geomOr "pwell"))
(metal1 = (geomOr "metal1"))
(metal2 = (geomOr "metal2"))
(metal3 = (geomOr "metal3"))
(metal4 = (geomOr "metal4"))
(cont = (geomOr "contact"))
(poly = (geomOr "poly"))
(pgate = (geomAnd poly pdiff))
(ngate = (geomAnd poly ndiff))
(nsd = (geomAndNot ndiff ngate))
(psd = (geomAndNot pdiff pgate))
(via = (geomOr "v1"))
(via1 = (geomOr "v2"))
(via2 = (geomOr "v3"))
(Ptap = (geomAnd psd pwell))
(Ntap = (geomAndNot nsd pwell))
(sub = (geomAndNot bkgnd pwell

...........
...........

(switch "extract") then
(extractDevice pgate
(poly "G")
(psd "S" "D")
(sub "B")
"pfet ivpcell"
)

(extractDevice ngate
(poly "G")
(nsd "S" "D")
(pwell "B")
"nfet ivpcell"
)

but I can't extract those components, I can only extract capacitors.

Someone can help me?

Thanks

 

Did you set the extract switch? If you did, what does the log show when
those rules are executed? Anything about bad formed shapes? You have
provided very little to work with here.

 

Yes, I did it.

This is the log file of the extraction operation.

Thank you

What means this error?

that means there must be a geomConnect() or geomStamp()
statement for this layer.

 

Or that it is derived from a layer that is in geomConnect() or geomStamp()
using something "reducing" like geomAnd() which inherits the connectivity
(geomAnd will always return a subset of the original layer - and so is
"reducing" - geomOr() will however expand the original layer, and so
doesn't transfer connectivity).

With this divaEXT.rul file I can't extract the transistor of the
layout.

your via statements look weird.
should probably be something more like

via(cont poly metal1 psd nsd)
via(cont sub__SD metal1)
via(cont sub__SD_2 metal1)
via(cont sub__SD_3 metal1)
via(cont sub_1 metal1)
via(cont sub_1_2 metal1)
via( via metal1 metal2 )
via( via1 metal2 metal3 )
via( via2 metal3 metal4 )

label statements also look weird to me.
try removing them.

 

Thank you.

Why do you think that it looks weird?

Do you think there is a problem with their definition?

(adlvtn = (geomOr "adlvtn"))
(nplus = (geomOr "nplus"))
(active = (geomOr "active"))

(sub_1 = (geomAnd adlvtn nplus))
(sub__SD = (geomAnd sub_1 active))
(sub__SD_2 = (geomAndNot sub__SD poly))
(sub__SD_3 = (geomAnd sub__SD_2 sub__SD))
(sub_1_2 = (geomAndNot bkgnd sub__SD))

 

in a correct statement, the first layer is the via and the rest
is the layers to be connected through this via.

in you car, the line

via(via cont poly metal1 psd nsd)

suggest that the via layer is connecting cont, poly, met1
and diffusion toghether, which is obviously not the wanted
effect. also there is no via connecting to met2, met3 or met4.

the label statement should look like label( metal1 metal1 )
which means that text on metal1 layer applies to metal1 shapes.

try it, we'll see
