Need to check everywhere that constant_expression is used in BNF, that it really does need to obey all the restrictions of constant_expressions, such as no hierarchical references, etc. Need to distinguish in text between constant expressions which have such restrictions and those which do not. -- Shalom Bresticker Shalom.Bresticker@motorola.com Design & Reuse Methodology Tel: +972 9 9522268 Motorola Semiconductor Israel, Ltd.

From: Shalom Bresticker <Shalom.Bresticker@motorola.com> To: etf-bugs@boyd.com Cc: Subject: Re: errata/416: check use of constant_expression Date: Fri, 15 Aug 2003 10:15:54 +0300 As an additional example of how careful we have to be about the term "constant expression", 12.2.1, para. 2, says that "The expression on the right-hand side of the defparam assignments shall be a constant expression involving only numbers and references to parameters." But it fails to note that constant function calls are also allowed. -- Shalom Bresticker Shalom.Bresticker@motorola.com Design & Reuse Methodology Tel: +972 9 9522268 Motorola Semiconductor Israel, Ltd.
