Hardware Design and Verification
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 “);
What is memory Memory is electronic component which can store information. it stores at certain address while reading from memory it retrieve the data from certain memory Block Diagram of Memory DUT module memory #( parameter ADDR_WIDTH = 32, parameter DATA_WIDTH = 64 ) ( input clk, input reset, //control signals input [ADDR_WIDTH-1:0] addr, input wr_en,
Definition : Fifo (synchronous ) The Synchronous FIFO has a single clock port for both data-read and data-write operations, it means it is used for synchronising across two process when two process are running on same clock. One source writes to the FIFO and the other sources reads out the FIFO where it sees the order
These are two block in verilog/system verilog which is used for writing Verilog behavioural code. initial block : it executes only once in time zero always block : As its name suggest , it is like infinity loop if there are no conditions are supplied, in case of some condition, it will execute on the given
Well, Lets take adder of following specification : it is one bit adder , one result , one bit carry So system verilog interface port definition will look like interface dut_if1; logic a_in, b_in, c_in; logic sum_out; logic carry_out; logic clock,reset; endinterface So Lets go through definition of each component , click here to get details information
