dbCreateInstTerm: Terminal not in instance's master

Hi, Cadence Family

I've created a cell named inva_lv, with dbMakeNet, dbCreateTerm, dbCreatePin for symbol view

; pcell: inva_lv

dbMakeNet(pcCV "VPP")

dbCreateTerm(dbFindNetByName(pcCV "VPP") dbFindNetByName(pcCV "VPP")->name "inputOutput")

dbCreatePin(dbFindNetByName(pcCV "VPP") dbCreateRect(pcCV '("pin" "drawing") list(1-hp:1-hp 1+hp:1+hp)))

Then I try to create inva_lv in another schematic pcCellView with dbOpenCellViewByType, dbCreateInst like below

; another pcell
masterIopinCv=dbOpenCellViewByType("basic" "iopin" "symbolr" nil "r")

dbCreateNet(pcCV "VPP")

dbCreateTerm(dbFindNetByName(pcCV "VPP") dbFindNetByName(pcCV "VPP")->name "inputOutput")

dbCreatePin(dbFindNetByName(pcCV "VPP") dbCreateInst(pcCV masterIopinCv "VPP" 1:1 "R0"))

masterCv=dbOpenCellViewByType("test" "inva_lv" "symbol" nil "r")

instId=dbCreateInst(pcCV masterCv "X0" 1:1 "R0" 1)

dbCreateInstTerm(dbFindNetByName(pcCV "VPP") instId dbFindTermByName(masterCv "VPP"))

CIW says "WARNING (DB-270000) :dbCreateInstTerm: Terminal not in instance's master"

Then the pin "VPP" in created inverter cannot be assign Net Name like below

So, I try to replace inva_lv by analogLib/pmos4

It's work like below

Am I missing something to build?

How can I fix it ?

Your help will be appreciated.
