Holger Vogt 27ba1e39df Small correction to previous commit. 2022-10-17 16:47:51 +02:00
Holger Vogt 06d349ff06 Add a limit of 0.999 to bipolar parameters mje, mjc, and mjs. 
The bipolar model is restricted to values < 1.
Fixes bug 583

Holger Vogt e2defea752 The derivative of pow shall use the new pow function as well, 
when compat mode LT is selected.
 2022-10-14 14:56:09 +02:00
Holger Vogt edab163192 If compatmode is lt, change the pow(x,y) and x**y functions: 
If x < 0, output only if y is integer number, otherwise output 0

Holger Vogt 98763c0add Note: ix: dc value used for op instead of transient time=0 value 
Former warning message or note only issued when dc value and
value at transient time=0 differ.

Holger Vogt 07bb809158 Iterations for op or dc may start with arguments 0 for ln(). 
To cope with this, and potential overflow in exp function,
some limits have been added.

Holger Vogt d1cbcb080c Re-format cktdojob.c 2022-10-07 13:03:35 +02:00
Holger Vogt f073fb5c05 Consecutive tran and ac simulation may lead to gross errors 
when TC or scale is used on the instance line of C and L.
Reason is the missing reset when CKTtemp is called once during each
simulation command. TC or scale is then applied again and again,
a reset is missing.

This patch adds a reset, i.e. the capacitance or inductance is
reset to its instance value in a call to *temp. It fixes bug#594.

Command 'alter' has been tested.

Resistance has not been tackled by this bug, because the line
here->RESconduct = here->RESm / (here->RESresist * factor * here->RESscale);
differs from
here->CAPcapac = here->CAPcapac * factor * here->CAPscale;
in that there is no accumulation of correction factors with here->RESconduct

calculated because the geometries are too small (< 1um).

Giles Atkinson aaa6798950 Fix bugs found while investigating Bug #585 (convergence failure only 
on Linux).  In dctran.c make it impossible for a transient simulation
to run far past its end time and fix an infinite loop attempting to remove
the automatically-inserted ending breakpoint.  In outitf.c fix memory
corruption if the simulation does over-run (change suggested by Holger Vogt).

Holger Vogt e5c162f126 dc sweep fails after transient sim: 
keep MODEDCTRANCURVE as provided by commit
7d8236766 ("b3ld.c, b4ld.c, b3v32ld.c: enable capacitance calculation during dc sweep", 2012-10-03)
Instead exclude current integration when MODEDCTRANCURVE is selected.
Unify setting ChargeComputationNeeded in b4vdld.c,
make it as in other b4xxld.c.

Holger Vogt 4c8324f166 VIN 3 0 PULSE (-1 1 2NS 2NS 2NS 50 NS 100 NS) is now standard 
(missing dc value).
So revert the warning message:
VIN 3 0 dc 0 PULSE (-1 1 2NS 2NS 2NS 50 NS 100 NS) yields
a note message (not a warning)
