[sv-bc] RE: [sv-ac] Support of two-dimensional interface instantiation ?

An 1800-2005 array of interface instances can have an arbitrary number
of dimensions, not just two.

Hi,

  In 1800-2005, it only supports two-dimensional interface
instantiation.
  Will 1800-2008 support two-dimensional interface instantiation?
  This feature is very commonly used to model array processor and FPGA
  architectures in which a system is composed of many similar building
  blocks. Each building block is identified by two indexes.


  For example,

    Interface array_cup_bus (input a, inout b, input clk);
      Inout data;
      Input r_w;
    endinterface: array_cup_bus

    module cup (array_cup_bus cup_bus);

    endmodule

    module mem (array_cup_bus cup_bus);

    endmoudle

    module array_cup (input a, inout b, input clk);

       array_cup_bus cup_bus [1:3][1:3] (a, b, clk);

       cpu cpu1(cpu_bus[1][1]);
       mem mem1(cpu_bus[1][1]);
       cpu cpu1(cpu_bus[1][2]);
       mem mem1(cpu_bus[1][2]);
       cpu cpu1(cpu_bus[1][3]);
       mem mem1(cpu_bus[1][3]);

    endmoudle
