What help do you need?

BTW:
ISR  is  the reverse saturation current (at TNOM)
IBV  is  current at V = -BV
BV  is the breakdown voltage

Note that one can have funny issues when computing I at V=-BV from
 I(v) = IS * (exp(v/(N*vt)) -1) + ISR * (exp((v+BV)/(NR*vt)) - 1) + GMIN * v
and comparing that to IBV.  Of course, I(v) should be continuous, so it seems to me that IBV is overconstraining the system, and maybe is just approximate.
