I would also change the term "operand" to some other term (like "leaf expression", for example). Outside of Verilog world, this term is usually used to describe the immediate arguments of operators, which is different from its semantics in Verilog. Having this unusual meaning in Verilog is very confusing. See http://en.wikipedia.org/wiki/Operand as a reference to the "usual" meaning. --Yulik. ________________________________ From: owner-sv-bc@server.eda.org [mailto:owner-sv-bc@server.eda.org] On Behalf Of Bresticker, Shalom Sent: Thursday, June 21, 2007 10:28 AM To: stuart@sutherland-hdl.com Cc: sv-bc@server.eda.org Subject: [sv-bc] D3a 11.2: operands Hi, 11.2 says, An operand can be one of the following: - Constant literal number, including real literals - Literal string - Parameter, including local and specify parameters - Parameter bit-select or part-select, including local and specify parameters - Any net type (see 6.6) - Net bit-select or part-select - Any net type (see 6.7) - Variable bit-select or part-select - Structure, packed or unpacked - Structure member - Packed structure bit-select or part-select - Union, packed, unpacked or tagged - Union member - Packed union bit-select or part-select - Packed array - Packed array, structure or union bit-select, part-select, element or slice - Unpacked array - Unpacked array element bit-select or part-select, element or slice - A call to a user-defined function, system-defined function or method that returns any of the above There seems to be redundancy here. "Any net type" appears twice. I think the second should be "Any variable type", but considering that we mean an object and not a type, it should probably be simply "Variable", as the next item is "Variable bit-select or part-select". "Packed structure bit-select or part-select" and "Packed union bit-select or part-select" are also included under "Packed array, structure or union bit-select, part-select, element or slice". The list could probably be made more compact as: An operand can be one of the following: - Constant literal number, including real literals - Literal string - Parameter, including local and specify parameters - Parameter bit-select or part-select, including local and specify parameters - Net - Variable - Net or variable bit-select or part-select - Structure, packed or unpacked - Union, packed, unpacked or tagged - Structure member - Union member - Array, packed or unpacked - Packed array, structure or union bit-select, part-select, element or slice - Unpacked array element bit-select or part-select, element or slice - A call to a user-defined function, system-defined function or method that returns any of the above Shalom Bresticker Intel Jerusalem LAD DA +972 2 589-6852 +972 54 721-1033 -- This message has been scanned for viruses and dangerous content by MailScanner <http://www.mailscanner.info/> , and is believed to be clean. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
