Joel,
Understanding that you are using another vendor's connector, I will =
still share with the group what our understanding of using connector =
models in HyperLynx is all about. Note that Samtec is not a direct user =
of HyperLynx, but we have worked with Mentor Graphics reps in an attempt =
to understand what certain "modules" of HyperLynx can support:
(1) HyperLynx LineSim utilizes a "SLM" format which basically uses a =
SPICE T-line and strips out the Z and TPD parameters.
(2) HyperLynx BoardSim requires manual entry of the lumped or =
distributed T-line parameters
(3) HyperLynx ELDO - these models are basically SPICE models, and =
apparently HyperLynx GHz (version 7 and higher, I think) that has a =
License of ELDO can use these single-line or multi-line model =
structures. We re-package our standard SPICE multi-line models by =
rearranging the node order to make the symbol in Hyperlynx more readable =
to the user...
Hopefully, this info helps other users of HyperLynx. We are not direct =
users of HyperLynx; only have obtained support information in order to =
attempt to support customers with connectors models. Users of other =
vendor's models should expect them to be able to support the above, =
since they are based on SPICE models.
I am hopeful that some other "expert" users of the different HyperLynx =
toolsets, including reps from Mentor Graphics, will chime in with even =
more helpful insights...

Subject: [SI-LIST] simulating connectors in Hyperlynx
We have a design where signals go through one or more connectors.
Most connector manufacturers supply models in HSPICE format which we do=20
not have or will be getting any time soon.
Hyperlynx has a mutliboard simulation mode which allows you to enter the =
parasitic L,R,C of the connection.
Does it make any sense to try to obtain the L,R,C values of the=20
connectors to put into the simulation.
Can these parameters be extracted from the HSPICE file if it is not=20
encrypted?
Thanks - Joel
