tunnel diode

I was wondering whether there is a model for a tunnel diode included in one of the Cadence libraries. I could not find any but might have no looked in the right places. If not, does anyone know how to best model a tunnel diode in Spectre?
I googled a bit around and have found a few examlples (see picture and also given link). BTW, I want to use the tunnel diode for a oscillator.

Thanks for any feedback.

There are a couple of papers in IEEE Xplore, for example
"SPICE model of the resonant-tunnelling diode"
Brown, E.R.; McMahon, O.B.; Mahoney, L.J.; Molvar, K.M.;
Electronics Letters
Volume 32, Issue 10, 9 May 1996 Page(s):938 - 940

If at first you do succeed, STOP, raise your standards, and stop wasting your time.

one of the higher level diodes supports tunneling..was often used to model gate leakage before bsim4 came along..
level=3 ?

BSIM4 has trap-assisted and band-to-band tunneling; I believe these are different effects than found in a true tunnel diode, where the energy bands are seriously contorted.
