Started discussion from Section 6.6.1

* Section 6.6.2: Remove BNF for repeat and while from the Syntax 6-9 
syntax box. Repeat and while have been separately mentioned preceding 
section in the new LRM
* Section 6.6.2: In the first paragraph remove the explanation about 
analog_for statements to Section 6.6.3 which deals with this explicitly. 
The explanation for analog_for in normal for is bit confusing. 
[analog_for and normal for statements have been split into two 
independent subsections to maintain clarity and also to better specify 
the semantics between the two]
* Global change as with other reviews: use shall not wherever possible 
instead of cannot
* Section 6.7 semantic rules: Contribution statement inside events has 
been explicitly disallowed. This was disallowed in the previous versions 
of the LRM also but this version has stated it clearly in the list of 
semantic restrictions. There might be some usefulness to adding 
contribution to initial_step events as part of initialization of branch 
potentials but this is not currently allowed. Suggestion was to raise a 
separate mantis item.
* Section 6.7.3.1 (cross operator): When talking about analog filter 
functions not being able to be used as direction argument dont mention 
about the evaluating to integer. Move this to the next section where the 
values of the direction argument is discussed
* Switching off events? This was discussed briefly again. The intent of 
the current LRM is to not use the direction argument to specify whether 
an cross event is on or off. Apparently that was one of the original 
intent of the direction argument as was discussed in reflector. There is 
a more global issue of controlling events and turning them on/off (there 
are couple of other proposals one looking at allowing events inside 
conditionals etc) - possibly in a more generic fashion. What is the 
capability in 1364 to turn on/off digital events.
* Section 6.7.3.2 (above): In general reference to ac, dc analysis in 
paragraphs uses capitalized versions of these strings. Change the 
reference in this section also to be consistent.
* Section 6.7.4; new section on digital events on analog behaviour. Tho' 
digital events are described as part of 1364 there are some restrictions 
on its usage within analog that is captured here. Make cross reference 
to chapter 8 for further details, which discusses mixed signal usage and 
behavior.

Chapter 6 review has been completed. The corrections/suggestions from 
the last few reviews will be incorporated and posted very soon.

Next Review: Chapter 4 (David Miller) on 7th Sept 2006

cheers,
Sri
