2.45  UNFAULT command

2.45.1  Syntax

unfault

2.45.2  Purpose

Undo any action from fault commands.

2.45.3  Comments

This command reverses the action of all fault commands.

It will also clean up any side effects of an aborted sweep command.

Unfault is automatically invoked on any clear command.

If you change the circuit in any other way, unfault will bring back the old on top of the changes. This can bring on some surprises.

2.45.4  Example

fault R66=1k
R66 now has a value of 1k, regardless of what it was before.

unfault
Clears all faults. In this case, R66 has its old value again.
unfault can bring on surprises. Consider this sequence ... 
V1   1   0    ac  1
C3   1   2    1u
R4   2   0    10k
fault C3=100p
C3 is 100 picofarads, for now.

modify C3=220p
C3 is 220 pf, for now. It will be restored.

modify R4=1k
R4 is 1k. It will not be restored.

restore
C3 back to 1 uf, but R4 still 1k.
