Safety Operation Area (SOA) checking

I am trying to adopt an ELDO command in SPECTRE. But I am having some
troubel in defining some parameters. See example below:

in ELDO
..SETSOA M <modelname> <paramname>=(min_limit, max_limit)

in SPECTRE
assertname ASSERT MOD=<modelname> PARAM=paramname MIN=min_limit,
MAX=max_limit

In ELDO the following parameter names are valid:
For MOS models - IG, IS, IB, VGD, VGS, VGB, VBS, VBD, VDS, POW, VS,
VD, VG, VB
For Two terminal device models - VPOS, VNEG, VDIP, I

In Spectre, only VGS, VDS, and VSB works for MOS models. And for
dipoles: V and I only.

Could anyone help me how to get the equivalent instance parameters for
these devices? Right now I need to have an equivalent parameter name
for the following: IG, IS, IB, VGD, VGS, VGB, VBS, VBD, VDS, POW, VS,
VD, VG, VB. But it will be great if you could provide for other
device models like capacitor, diodes and BJTs.
