How is randomization done in SystemVerilog ? To enable randomization on a variable, you have to declare variables as either rand or randc. The difference between the two is that randc is cyclic in nature, and hence after randomization, the same value will be picked again only after all other values have been applied. If randomization succeeds, randomize() will return 1, else 0.

What is callback : According to wikipedia : A callback is a executable code which is passed as an argument to other code. It allows a lower level software level to call the a subroutine or function of a higher level layer :
Constrained random verification (CRV) has generally been accepted as a gateway to higher functional cross coverage and, thus, verify scenarios that are very difficult or impossible to anticipate (i.e., not in the test plan).

injection queue for router 0 is queue 0, the packet injection queue for router 5 is queue 5 and so on. The packet ejection queues for routers are numbered from NUMROUTERS to 2*NUMROUTERS-1, i.e. the packet ejection queue for router 0 is queue 1024 (since we have 1024 routers), the packet ejection queue for router 1 is queue 1025, and so on.
Dec 17, 2015 · Similarly, SystemVerilog’s mailboxes provide processes to transfer and retrieve data in a controlled manner. Mailboxes are created as having either a bounded or unbounded queue size. A bounded mailbox becomes full when it contains the bounded number of messages.

  • Because after 3 years of not using UVM and almost no SystemVerilog, I am trying to get the rust off by revisiting questions I've had in the past. Yes, I was working at a place that favored vanilla Verilog, and where SystemVerilog was discouraged and UVM was not used.

  • introduction. How is the divider implemented in FPGA? Of course, it is not allowed to use "/" and "%" to achieve. Although there is a division instruction in Verilog HDL language, the divisor in the division operator must be a power of 2, so division by an arbitrary integer cannot be achieved, which is largely restricted Its field of use.
  • Ans: The module is the basic building block in verilog which is used in creating a design. Systemverilog adds a new block called program block which can be declared using the keywords program and endprogram. The program block separates the design and testbench. The program block and module differs in syntax also.

Mar 16, 2019 · SystemVerilog introduces this in RFM 18.5.5, a group of variables can be constrained using unique constraint so that no two members of the group have the same value after randomization. Let’s assume that we have a dynamic array with size unknown, and we would like to constrain the size between 10 and 15. So we can just write our code as follows:

Most application require to randomize elememts of array.Arrays are used to model payload,port connections etc. SystemVerilog has Fixed Arrays,Dynamic arrays,queues and Associative arrays. If an array is constrained by both size constraints and iterative constraints for constraining every element of array.

So the question arises as to how to integrate SV Simulator, single threaded system, with software multi-threaded system. Solution is to design a software module which takes care of multiple threads and socket handling. Samir Palnitkar Verilog HDL A Guide to Digital Design and Synthesis (1st Ed.)

Jan 31, 2017 · Runtime complexity of STL Queue Queue In the C++ STL, a queue is a container adaptor.That means there is no primitive queue data structure. Instead, you create a queue from another container, like a list, and the queue's basic operations will be implemented using the underlying container's operations.
