WebApr 6, 2024 · In SystemVerilog, we can write arrays which have either a fixed number of elements or a variable number of elements. Fixed size arrays are also known as static arrays in SystemVerilog. When we declare a static array, a fixed amount of memory is allocated to the array at compile time. WebIn SystemVerilog, arrays may have either packed or unpacked dimensions, or both. Consider this example: reg [3:0] [7:0] register [0:9]; The packed dimensions are [3:0] and [7:0]. The unpacked dimension is [0:9]. (You can have as many packed and unpacked dimensions as you like.) Packed dimensions: are guaranteed to be laid out contiguously …
