Hardware Design and Verification
In this post I will talk about how fork join works So when The process has to be run in parallel , fork join method is used So there are three type of join after fork are available in system verilog fork join fork join_any fork join_none So I will explain in terms of
so question what is singleton class in system verilog as its name suggest Singleton -> it will be only once …. what is once , it is one object creation next time it will return handle of first object So lets see how it done through program // Singleton example // https://testbench4u.com

Welcome to section uvm question and answer part1 , I will try to put around 20 to 30 questions and answer related to UVM Lets Start What are some of the benefits of UVM methodology? UVM is a standard verification methodology which is getting standardized as IEEE 1800.12 standard. UVM consists of a defined methodology
What is difference between queue and mailbox? A mailbox is a built-in class around a queue that uses semaphores to control access to the ends of a queue. A mailbox only has FIFO element ordering whereas you can access the head, tail, or middle elements of a queue. you typically use a mailbox when there
How many parallel processes does this code generate? fork for (int i=0; i < 10; i++ ) begin ABC(); end join Since the “for” loop is inside the fork join, it executes as a single thread. Which keyword in SystemVerilog is used to define Abstract classes? Sometimes a class is defined with an intention to
What is extern ? extern qualifier indicates that the body of the method (its implementation) is to be found outside the class declaration. before the method name, class name should be specified with class resolution operator to specify to which class the method corresponds to. Example-1: In the example below, creating the object of virtual class
First One need to calculate no of block in cache, by dividing the total cache size by each cache line size and then no of sets is evaluated by dividing no of block by x (x is way set associative ) index bit : no of bit used to represent each cache line size remaining
