The curly brackets {,} are used for this operation. It seems casting from unpacked to packed can be made easily when I read LRM[*]. To assign values from a mixed array to a packed array, you can use concatenation to combine the bits from the elements of the mixed array to match the correct "shape" of the packed array: System verilog Tagged unpacked arrays, unpacked arrays in system verilog Unpacked Arrays in SystemVerilog by Praful Kharade Posted on October 12, 2024 A discussion of how Verilog vectors and arrays work. An array of vectors might iterate over the array of instances. I strongly suggest using a queue/push operation instead of array concatenation—much more efficient. I thought that packed arrays are stored contiguously and as such can be treated as a 1D vector. You need to … wire [a-1:0] array [b-1:0]; How can I OR the b array elements and get an a bits result in 1 clk? Thank you The below diagram shows storing packed array as a contiguous set of bits.
