Holger Vogt fac1d3a79c ASRC (B-Source) error message is cryptic, as it does not tell 
which B-Source failed.
Add a hint to the ASRC error message on the name of the
B-Source instance.

Holger Vogt f06496c912 Enable command 'optran' in spinit or .spiceinit, 
when the circuit is not yet loaded.
Then the optran data are stored in static variables,
until optran is called again with arg NULL from inp.c,
to set the data in ft_curckt->ci_defTask.

Holger Vogt 493cf73f7f optran is only selected when the 'optran' command has been processed. 
If not, the call to the OPtran() function returns the previous
'converged' value.

Holger Vogt f0cb886af1 Add command 'write_ic' 
Write out the right hand side status of the matrix in format
    .ic = V(node_xx)
    This may be possible at the end of a simulation or after a 'stop'
    of the simulation, which may be resumed again afterwars. This
    status may be used to start another simulation with these
    parameters by inluding into the netlist.

Holger Vogt df0792818f Transient op calculation added to the standard operating point code. 
When standard iteration, gmin stepping and source stepping fail,
try a transient simulation (like tran with uic option) to
determine the op. Implemented for AC and Tran simulation.

Holger Vogt a08e6a0676 Add new SOA parameters (safe operating area) for BJT. 
We now scan for max of Ic, Ib, power, taking into
account the max allowed temperature, using the thermal
resistance rth0 model parameter between juntion and ambient.

Two user options are there: If rth0 is given, we calculate
a derating of the max power allowed.
Without a constant max power according to model param pow_max
is assumed.

The new model parameters for the bipolar model are:
pow_max, ic_max, ib_max, te_max, and rth0, in addition
to the already existing vbe_max, vbc_max, adn vce_max.
