Spectre Netlist error

[tanzil_dhk]

I have designed an inverter using nmos4 and pmos4(NCSU_Analog_Parts) and edited the width and length with varriable Wid and Len. After changing the Drain Diffusion Area value becomes Wid*2.5*iPar("MinL") as it should be.

However every time i try Netlist and Run, i get the following errors

"input.scs" 17 : Function 'iPar' is undefined or is used recursively
"input.scs" 17 : Function 'iPar' is undefined or is used recursively
"input.scs" 18 : Function 'iPar' is undefined or is used recursivelyl
"input.scs" 18 : Function 'iPar' is undefined or is used recursively
"input.scs" 20 : Function 'iPar' is undefined or is used recursively
"input.scs" 20 : Function 'iPar' is undefined or is used recursively
"input.scs" 20 : Function 'iPar' is undefined or is used recursively
"input.scs" 21 : Function 'iPar' is undefined or is used recursively

I tried to edit CDF parameter for nmos4 and pmos4 by trying to edit paramenter MinL(assuming this is source of error) as parseasCEL = yes and parseasNumber = yes. But it did not improve a bit. Please tell me what to do.

Note : i was following this tutorial and did exactly what is said but same errors.

Maybe iPar() is not a function that has been defined to Spectre.
It looks more like a Skill function that has to be evaluated, not
passed literally to the netlist. How to force or fix it, though, I
do not know.

You could try a different route, of making the drain area &
periphery respond properly to the passed geometry params
rather than looking for "help from above" that seems missing.

The problem is solved when the following environment variable is set......
setenv CDS_Netlisting_Mode Analog
Infact not setting the above variable would cause another error during LVS check. So make sure this is set.
