RE: A comment

Thanks Dave for the answer.  I am not sure
how that sentence escaped my attention, I
see it now...

Thanks,

Hello Arpad,
as with most of the tolerance values used in the analog functions, if they are 
not specified then they will default to your particular simulators default values.
This will vary across simulators.
For example,
exprTol may default to a really large number.
timeTol may default to some function of the current timestep size.


LRM 2.3 - 5.10.3.1 mentions this in the last sentence of second paragraph:

"If the tolerances are not defined, then the tool (e.g., the simulator) sets 
them. If either or both tolerances are defined, then the direction shall also 
be defined."

hope this helps,

Cheers...
Dave
