Pin "VDD": floating input/output

SUBBHAREDDY

Hi

In my schematic, For an inverter A(input),ZN(output),VDD(inputOutput), VSS(inputOutput) pins are present.

Through skill code i removed "VDD" and instantiated "vdd_inherit" symbol.

when i do check and save i used to get the below warning :

Pin "VDD": floating input/output

Here is the code i had written :

 pindb=car(setof(x cv~>instances (x~>pin~>term~>name=="VDD")))

x_cord = car(pindb~>xy)
y_cord = cadr(pindb~>xy)

dbDeleteObject(pindb)

symbolId = dbOpenCellViewByType("basic"  "vss_inherit" "symbol" nil "r")
schCreateInst(cv symbolId nil x_cord:y_cord "R0")

schCheck(cv)

Warning: Pin "VDD": floating input/output.

Pls let me know what would be the problem  

Thanks and regards

Subbhareddy
