Queue Methods: Queues also provides several built-in methods to access/modify queue. The size() method returns the number of items in the queue. Feel free to write down any query if you have regarding this post. The optional "with" expression should not include any side effects; if it does, the results are unpredictable. These locator methods allow searching an array for elements (or their indexes) that satisfies a given expression. A queue is created in the program block, it gets passed to methods and manipulated. Array Locator Methods In SystemVerilog: The unpacked array and queues use this array locator method for searching an array element(or index) that satisfies a given expression.
