WebSystemVerilog Enumeration. An enumerated type defines a set of named values. In the following example, light_* is an enumerated variable that can store one of the three possible values (0, 1, 2). By default, the first name in the enumerated list gets the value 0 and the following names get incremental values like 1 and 2. The user can assign ... WebThere's not a special function to do it or anything, you just have to declare a bus the width of the product of the dimensions, and assign the various slices of the array into the bus. For example if you were mapping a [10] [10] array to 1D, you would declare a 100 bit bus, where slice [0] is [9:0], slice [1] is [19:10], etc.

The string data-type is an ordered collection of characters. The length of a string variable is the number of characters in the collection which can have dynamic length and vary during the course of a simulation.
