Hi all
NOW I use calibre extraction the RC using calibreview,
because RFMOS model
extraction type is Gate-level
I use a xcell file.

Layout source

p18_ckt_rf p18_ckt_rf
n18_ckt_rf n18_ckt_rf

but there are some warnings: HCELL p18_ckt_rf not located or not allowed
HCELL n18_ckt_rf not located or not allowed
the calibre is 2006.01

can anyone tell me why.
thanks
 

calibra rcx

I have the same problem. i think I HAVE set the correct the path of xcell.

why?

advice , welcome!
 

Re: calibre rcx

Hi yhq0413,

Sorry to trouble, but why do we use Gate-level instead of transistor-Level?
I use transistor-Level to do the post-layout simulation, the NF of the LNA degraded too much, what is the problem?

many thanks!!!
