Systemverilog packed array. Queues In SystemVerilog: In your system Verilog, if you are using a single thread, in that the insertion and extraction order of array elements are important, then the best option is the queue. Clear every element of fifomem. By using a queue we can develop the FIFO, but in that FIFO can use it for the single thread, if you want to use for the multiple threads then you need to use the mailbox. The size of a queue is variable similar to a. SystemVerilog Queue. But to do so you must define a new type using typedef and return that type. Hi all, I try using a queue of classes but there seems to be a problem when trying to read an item from the queue. Following Associative array methods are supported by SystemVerilog: num() & size() ... Queue is introduced in SystemVerilog. Description. In arrays this array locator methods travel in an unspecified order, these array locator methods will be used “with” keyword, otherwise, it won’t work. Chris Spear.
