It is recommended to pass arrays by reference whenever possible for performance reasons. If you want your function to modify the array, use ref. If you want your function to read the array, use const ref. Example:

Your immediate inputs are highly appreciated. WebApr 6, 2024 · Static arrays are generally simpler to use than dynamic arrays and are similar to verilog arrays. Therefore, we will discuss static arrays in more depth in the rest of this post. In the next post in this series, we will talk about more advanced SystemVerilog arrays. This includes a discussion of dynamic arrays, queues and associative arrays.
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.
