HI Doron,

 

Please, see my comments below. I am attaching a new version (also
uploaded into Mantis).

 

Thanks,

Dmitry

I have reviewed 1683. Here are my remarks:

 

*	End of page 2, 

 

       "The zero delay indicated by ##0 is understood to be from the end
point of the first sequence, 

         which occurs at a tick of the first clock, to the nearest,
non-strictly subsequent tick of the second 

         clock, where the second sequence begins."

   

         I would replace  "non-strictly" by "possibly overlapping".

[Korchemny, Dmitry] I rewrote it as: "... occurs at a tick of the first
clock, to the nearest, possibly overlapping tick of the second 

         clock..." (deleted "subsequent" as well). Made this change in
all similar cases.

 

*	At the end og page 3, I would add:

 

                If clk1 and clk2 are not identical, then the sequence

                @(posedge clk0) sig0 ##1 @(posedge clk1) sig1[*0:1]

                is illegal because of the possibility of an empty match
of sig1[*0:1], which would make ambiguous

whether the ending clocking event is @(posedge clk0) or @(posedge clk1).
Like in a singly clocked sequence, the operands of ##0 shall not admit
empty matches. 

 

[Korchemny, Dmitry] In singly clocked sequences the operands of ##0 may
admit empty matches, e.g., a[*0:2] ##0 b[*0:2] is legal and it is
equivalent to a[*1:2] ##0 b[*1:2]. As for the multiclocked sequences
there is already a sentence in the original text: "When concatenating
differently clocked sequences, the maximal singly clocked subsequences
are required to admit only nonempty matches."

 

*	Need to modify 16.15.1 (a lot of work)

[Korchemny, Dmitry] Done.

 

Doron
