- * COMPATABILITY WARNING!
- * special note:  for backward compatability to much older models, spice 2G
- * implemented a special case which checked if B-E leakage saturation
- * current was >1, then it was instead a the B-E leakage saturation current
- * divided by IS, and multiplied it by IS at this point.  This was not
- * handled correctly in the 2G code, and there is some question on its
- * reasonability, since it is also undocumented, so it has been left out
- * here.  It could easily be added with 1 line.  (The same applies to the B-C
- * leakage saturation current).   TQ  6/29/84
