TSMC 90nm library spice deck

Hello everybody,

I needed the spice netlists for the library cells in the TSMC 90nm
library. We had approached the cadence vendor for USF
but they said they only provide front end files, i.e., .lef
and .tlf(or
..lib) files, but no back-end files while includes the .sp files. Does
synopsys
provide this as well on request?

I was wondering if somebody could help me out in obtaining this. The
only
other option for me is to use spice files for 180nm OSU library and
scale it somehow...which will be tricky. Hand writing the spice files
for the library will be too time consuming and I am trying to avoid
that.

I would really appreciate any help on this.

Thanks,
Koustav

 

Hi,

I think you should contact TSMC directly.

Hi JD,

Thanx for ur response. Do you know anybody who asked TSMC any time
about their library spice decks? Do they respond? I heard vendors are
really reluctant in giving away these...

Thanks,

Hi,
If you are not design company intend to tape out with the TSMC 90nm
CMOS process, it takes quite long time to get the PDKs from them, and
you need assign NDA with them.

There is some other places you may get some models for TSMC 90nm
process, such as MOSIS, you can go to their website and search it.

Hi,
are you doing real work or is this student work or just for fun? (Who
do just for fun work with Cadence anyway?)

You could also try the "50nm" technology that J. Baker is offering on
his course homepage http://cmosedu.com

 

Hi JD,

Thanx for ur suggestions. My problem is that all I needed was a tech
library with all (libcells.sp, .lib, libcells.v, .lef ) files with
different drive strengths. The OSU 180nm library provides these files
but most cells in library does not have different sizes. I will try
contacting TSMC/MOSIS directly then.... hope they turn out good.

Thanks,
Koustav

 

Hi Svenn,

Thanx for ur suggestions. My problem is that all I needed was a tech
library with all (libcells.sp, .lib, libcells.v, .lef ) files with
different drive strengths/sizes. The OSU 180nm library provides these
files but most cells in library does not have different sizes. Jake
Baker is only providing the spice model file but not the transistor
level implementation of a library in spice, and I also need
the .lib, .libcells.v etc files for that library as well. I cud get
even 22nm model file from BPTM no problem with that......

Thanks,
Koustav
