22.13 says, "- $display, $write, $fdisplay, $fwrite, $swrite, and their variants - The integer % format specifiers (h, d, o, b, c, u, and z) may be used with any of the SystemVerilog integral data types, including enumerated types and packed aggregate data types. They shall not be used with any unpacked aggregate type." "- %u and %z format specifiers - For packed data, %u and %z are defined to operate as though the operation were applied to the equivalent vector. - For unpacked struct data, %u and %z are defined to apply as though the operation were performed on each member in declaration order. - For unpacked union data, %u and %z are defined to apply as though the operation were performed on the first member in declaration order. - %u and %z are not defined on unpacked arrays." 1. There is an apparent contradiction, that the first part seems to say that %u and %z, among others, "shall not be used with any unpacked aggregate type", and the second part says that they can. 2. If %u and %z can be defined for unpacked structs and unions, why not %b, etc. ? Shalom Shalom Bresticker Intel Jerusalem LAD DA +972 2 589-6852 +972 54 721-1033 I don't represent Intel
