Hardware Design and Verification
implication operator as it name suggest it is something related to “the conclusion that can be drawn from something” same thing is valid for system verilog as well where can you use in SV , it will be used where you want certain things you want to constraint certain things based on certain value/expression/signal consider
When the size of the collection is unknown or the data space is sparse, an associative array is used, which does not have any storage allocated until it is used. That means, it is dynamically allocated, but has non-contiguous elements. Associative array’s index expression is not restricted to integral expressions, but can be of any
What do you mean by synthesis : The RTL code which is synthesizable which can be implemented in hardware, when you write any logic design, it has to be synthesizable, it should implement in terms of logic gates There are many tool which does synthesis , it gives the idea of pre fabricated hardware in
BLOCK DIAGRAM class seqItem extends uvm_sequence_item; `uvm_object_utils(seqItem) logic [8-1:0] rdata; logic wfull; logic rempty; rand logic [8-1:0] wdata; logic winc, wrst_n; logic rinc, rrst_n; function new (string name=”seqItem”); super.new(name); endfunction endclass
No it is possible , as it is not supported , you cannot have different input type of same function type, like Class myClass { int Func(int x) { } int Func(string s) { } int Func(int x,string s) { } }
Poly in means , means a same thing is known by different name Lets take a example here class Animal; virtual function AnimalType(); $display(“ Welcome to Type Animal”); endfunction endclass class Dog extends Animal; function AnimalType(); $display(“Welcome to Dog Animal Type”); endclass class Cat extends Animal; function AnimalType(); $display(“Welcome to Cat Animal Type”); endclass class Horse extends Animal; function AnimalType(); $display(“Welcome
UVM is built on system verilog , so what ever UVM is doing underlying coding is SV So in general , lets take broader view with respect to ther language if you have heard of JAVA , and Hibernate Hibernate : is a framework built on java helps in managing data base beautifully , if
This system function searches the list of plusargs (like the $test$plusargs system function) for a user specified plusarg string , If the string is found, the remainder of the string is converted to the type specified in the user_string and the resulting value stored in the variable provided. like if($value$plusargs(“STRING=%s”,s)) $display(” GOT STRING cHAR “);
VLSI: As its full name is “ Very large scale integration” , something to do with large no of transistors integration. Where VLSI is used : it is used to develop any electronic device with a lot of functionalities Like : Mobile processor , Computer processor /server , Bluetooth device /Wireless Device /Memory Now if
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
