ID:13573 SystemVerilog Array Querying warning at <location>: argument to <name> does not denote an object or type with array dimensions, returning 'x

CAUSE: In an array querying system function call Verilog Design File (.v) at the specified location, you referred to an object or type that has no dimensions, for example, a scalar, a real, or a struct/union data type. As a result, the system function call returned the unsized bit literal 'x.

ACTION: No action is required. To remove the warning, change the first argument to refer to an object for which $dimensions() returns a non-zero value.
