Good book/documentation for CMI (Cadence Spectre)?

Hi all,

could someone recommend me some good book/documentation/examples for
Cadence Spectre Compiled Model Interface?

I am stuck with "CMI Reference 4.0" (btw, I wonder why Cadence did not
include "CMI Reference 5.0" in Europractice distribution of MMSIM 7)
and some non-documented examples in .../spectrecmi/samples and .../
spectrecmi/src.

Any help is appreciated.

Kind regards,
A.W.

Did someone managed to get opamp.c from .../spectrecmi/samples
working?
It compiled well and I got the library libopamp.so which I included in
cmiConfig; Spectre recognized it; I have placed the opamp model into
my netlist, but the opamp does not work (at all). Not in tran, ac.
I will try other examples, hopefully some will work.

Kind regards,
A.W.

 

I replied to this on another forum. In general Cadence do not ship CMI
documentation, as this is rather a special task and needs expert support.
It has historically been provided with the Europractice bundle though.

You should contact Europractice for support.

However, developing CMI models is something that should be rare - only if you
have a detailed device model which you are going to need absolutely the highest
performance - typically for device models where you need maximum optimisation.
Usually VerilogA is sufficient (even for device models).

Andrew.
