[sv-ac] RE: call to vote on 2088

I vote "no" on 2088.

Major comments:

* Covergroup sampling in checkers require some clarification. In case
when the clocking event refers to a checker variable, it will happen in
the Observed region, and some checker variable will have their old
values (those who evaluate before the variable in the clocking event)
and others will have the new values already assigned.

E.g.,

checkvar bit newclock = 0;
checkvar bit a, b;

assign a = regular_var_1;
assign b = regular_var_2;

always_check @clk newclock <= !newclock;

covergroup cg1 @(newclock);
... // References to a and b
endgroup

Here you cannot tell what the evaluation order is: newclock, a, b; a, b.
newclock, etc.

Minor comments and friendly amendments:

* Need to insert references to subclauses describing the covergroups.

Page 2.

* "Covergroup declarations and instances" -> "Covergroup declarations
and instances." - missing the trailing dot.

* The added text in the new section should be in blue.

* A covergroup may reference either input signals of the checker or
checker variables, including free variables."

The term "input signals of the checker" is not defined. Is the intention
about the input formal arguments? Also, why global variables defined
elsewhere are disallowed in the covergroup?

* Need to fix fonts throughout the document: Arial appears in many
places instead of Times New Roman.

Page 3.

* "bins active = { [1'b1 };" -> "bins active = { 1'b1 };"

Thanks,
Dmitry

Subject: call to vote on 2088

Hi Folks:

Since my last call to vote on 2088 did not reach the reflector,
I am calling for a new, 1-week vote.  This is that call.

I have copied the eligible voters individually because the 
reflector seems unreliable.

Please send your ballot both to the reflector and to me 
individually.

Please vote if you are eligible.  See the details below.

J.H.
