This is a draft proposal for Mantis 1209, to clarify that parameters can be aggregates, and in particular arrays. This is one of many cases where the BNF allows a certain construct, but the LRM does not describe it, and it is not obvious to some readers (like me) that it is allowed unless explicitly pointed out. The purpose of the draft is to elicit comments in order to improve the final proposal. A parameter can also be declared as an aggregate type, such as an unpacked array or an unpacked struct. An aggregate parameter must be assigned to or overridden as a whole; individual members of a parameter aggregate may not be assigned or overridden separately. However, an individual member of a parameter aggregate may be used in an expression. For example, parameter logic [31:0] P1 [3:0] = '{ 1, 2, 3, 4 } ; // array parameter declaration if ( P1[2] [7:0] ) ... // use part-select of individual element of the array Thanks, Shalom Shalom Bresticker Intel Jerusalem LAD DA +972 2 589-6852 +972 54 721-1033 I don't represent Intel
