WebThere are two types of arrays in SystemVerilog - packed and unpacked arrays. A packed array is used to refer to dimensions declared before the variable name. bit [3:0] data; // Packed array or vector logic queue [9:0]; // Unpacked array A packed array is guaranteed to be represented as a contiguous set of bits. WebDec 15, 2024 · declares a task that accepts one argument, a dynamic array of strings. This task can accept any onedimensional unpacked array of strings or any one-dimensional dynamic array or queue of strings. I am interpreting this as if the formal argument to the function is dynamic array then one can call this function with another dynamic array.

WebApr 12, 2024 · 1 it is unclear if a struct with dynamic array can be passed to an import function. However, the dynamic arrays themselves can be passed to the import (but not to the export) function as arguments. So, try to pass it as a separate argument instead. – Serge Apr 13, 2024 at 0:15 @Serge Thanks. I am familiar with passing dynamic arrays … WebDynamic arrays are arrays where the size is not pre-determined during array declaration. These arrays can have variable size as new members can be added to the array at any time. Consider the example below where we declare a dynamic array as indicated by the empty square brackets [] of type rand. dgk architects
