In short: To generate an array of unique random values in SystemVerilog, mark the array rand and add one unique constraint: constraint c { unique {arr}; }. The solver then fills every element with a different value. You can also list extra values inside the braces to keep those out of the set, which is…
In short: When you need an array of distinct values in a mixed order but do not need full randomness, you can skip constraints. Fill the array with known distinct values, such as the index itself, then call the built in shuffle() method to rearrange them. The result has no repeats and a random order,…
In short: SystemVerilog gives you four main array types beyond the fixed size array: the dynamic array (size set at run time with new[]), the associative array (sparse, indexed by any key such as a string), the queue (an ordered list that grows and shrinks with push and pop), and each has its own methods….
