Cadence using delay() in corners...? possible?

[jemos]

Hello,

I'm trying to use a performance function in corners analysis (Virtuoso Analog Corners Analysis)
like:

delay(v("/ventrada" ?result 'tran) 1.8 3 "either" v("/saida" ?result 'tran) 2.54 3 "raising" 0 0 nil nil)

If I define the performance:

average(v("/ventrada" ?result 'tran))

It goes OK, if I use the delay above in normal simulation (Virtuoso Analog Design Environment...) it goes OK, but if I use it as a performance function in corners analysis it doesn't work, returns error.
Output is:

Invalid expression for Corners print: delay(v("/ventrada" ?result 'tran) 1.8 3 "either" v("/saida" ?result 'tran) 2.54 3 "raising" 0 0 nil nil)

I'm starting to think that delay() doesn't support data returned in corner analysis? any idea?

Thanks for any help!

PS: I'm not sure if I'm posting this on the correct forum...
