From: "Katz, Jacob" To: "sv-ac@eda-stds.org" Date: Wed, 16 Nov 2011 23:22:12 +0200 Subject: RE: [sv-ac] Updated proposal for 3069 Ben, Do you think it really adds valuable information to the definition? It seems like this example wouldn't introduce any new information, and in fact more relates to the fact that it is allowed to have similarly named blocks under generate conditionals. What others think? -------------------------------- Jacob M.

A given module, interface, checker, or program may shall contain at most one global clocking declaration; it shall be an error otherwise. Global clocking shall not be declared in a generate block.

Manisha From: owner-sv-ac@eda.org [mailto:owner-sv-ac@eda.org] On Behalf Of Katz, Jacob Sent: Wednesday, November 16, 2011 2:50 PM To: sv-ac@eda-stds.org Subject: [sv-ac] Updated proposal for 3069 Following the recent discussion, I uploaded a modified proposal for 3069 which disallows global clocking declaration in generate blocks. Please review at http://www.eda-stds.org/mantis/view.php?id=3069. The changes are as follows. * Replaced: Global clocking may be declared in a module, an interface, a checker, or a program, including inside a generate block therein. A given module, interface, checker, or program may contain multiple global clocking declarations a ppearing syntactically, for example within generate conditionals. However, any of its instances in the elaborated design description shall contain at most one global clocking declaration; it shall be an error otherwise. With: Global clocking may be declared in a module, an interface, a checker, or a program. A given module, interface, checker, or program may contain at most one global clocking declaration; it shall be an error otherwise. Global clocking shall not be declared in a generate block. * Removed references to generate blocks from the hierarchical lookup rules. * Removed the last two examples -------------------------------- Jacob M.
