Subject: Re: [sv-bc] Array query functions on interface port and instance array
But I don't see any reference in the LRM that allows array query functions on interface port or instance array. Unapacked array section does not include interface port or instance array. Please help me if I miss any part in the LRM.
Regards Surya

Your failures seem to be tool limitations, not language restrictions. ShalomSV 2009 draft 7a LRM has described array query functions in "20.7 Array querying functions" which uses reference of clause 7 where the unpacked array is defined. The clause 7 defines unpacked arrays of different data types. But it is not clear what will be the expected behavior of array query functions if they are applied on instance array of interface port array. For the following case what will be the expected behavior? interface a; endinterface module test(in1,in2,out); input [7:0] in1,in2; output reg [7:0]out; a a[3:0](); assign out = $size(a); bottom inst(a); endmodule module bottom(a a[4]); byte out; assign out = $size(a); endmodule Some simulators fail and some pass for the above case.--------------------------------------------------------------------- Intel Israel (74) Limited This e-mail and any attachments may contain confidential material for the sole use of the intended recipient(s).
