ID:13574 SystemVerilog Array Querying warning at <location>: second argument (<number>) to <name> is not a valid dimension for object or type with <number> dimensions, returning 'x

CAUSE: In an array querying system function call at the specified location in a Verilog Design File (.v), you attempted to query a dimension that does not exist in the array object or type. As a result, the system function call returned the unsized bit literal 'x.

ACTION: No action is required. To remove the warning, specify a legal dimension. Dimensions are numbered from 1 to N, with 1 referring to the first unpacked dimension and N referring to the last (least-significant) packed dimension.
