- Champions Feedback

Dmitry 3115 2412 3135

2476 Failed Problematic

Dave Rich suggested major changes.

3113 Failed: Suggested different BNF structure

2412 Clock inference in sequences

Failed: Mostly editorial changes

3135 Failed: Incorrect fonts.

- New Issues

3595: triggered sequence method needs clarification

Ben: Entered mantis item as a result of last weeks discussion.

Question was whether sequence.triggered() generates one event

or two.

Ed: How is this different from event.triggered()? It should behave

the same way to be consistent.

Ed Wouldn't it be better to forbid the use of triggered() in an

event?

Dmitry: New mantis item should be routed to SV-BC.

3610: Sequence methods with sequences admitting empty match

Dmitry: What does sequence.triggered() mean if the sequence admits an

empty match. If allowed, triggered would be true at every time

step. Should be forbidden.

- Issue resolution/discussion

3069 Global clocking

Dmitry: Jacob & Scott reached an agreement on how to implement proposal.

Will call for an e-mail ballot.

3033: Allow procedural control statements in checkers Mantis Proposal has been reviewed:

Tom: Assertions in checkers should use sampled values of all variables

(even deterministic checker variables)

Dmitry: Believe that this is taken care of by new definition of sampling.

Tom: Example in 17.7.3. It seems troubling that a single rand variable

could be solved multiple times in a time step. Would be difficult

to debug.

In addition: What about the second solving? Would it use constraints

clocked by both clocks? Or just one clock?

Dmitry: But could be useful to code this way.

Tom: Shouldn't all assignments be prohibited to rand variables?

How does the simulator know when to solve for it, and when to assign

it?

Dmitry: We put such an example in the 2009 LRM in 17.7.1

Dmitry: Will call for an e-mail vote

- Opens

Clocking Blocks:

Ed: Confusion in LRM? Question about whether @(clocking_block) is really

equivalent to @(clocking_event_defined_in_clocking_block)
