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 -----Original Message----- From: John Havlicek [mailto:john.havlicek@freescale.com] Sent: Monday, December 31, 2007 7:00 PM To: sv-ac@eda.org Cc: Bustan, Doron; eduard.cerny@synopsys.com; yaniv.fais@freescale.com; john.havlicek@freescale.com; Korchemny, Dmitry; Manisha_Kulshrestha@mentor.com; johan.martensson@jasper-da.com; piper@cadence.com; Seligman, Erik; bassam.tabbara@synopsys.com; thomas.thatcher@sun.com 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.
