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
Write system verilog code to generate packet value between 10 to 100, if packet type is “Good” // Code your testbench here // or browse Examples // Run randomized classs //testbench4u.com typedef enum {good, bad} packet1; class txn_crc; rand bit [7:0] crc; rand bit [8:0] packet; rand packet1 packet_type ; constraint packet_width { if (packet_type==good)
Virtual sequencer : it contains handles of the sequencer which are located in different agent Q. Question is when do we use it ?? Why do use it if something has to be synchronized , in general stimulus generation across different interface has to be synchronized, which is done by Virtual sequencer , virtual sequences
Q. Lets take a adder has port definition Input port ( A : 1, B : 1 bit , C: 1 bit ) Output port( Sum : 1 bit, carry : 1 bit ) Write UVM sequence item ? Answer : Lets define a_in ,
UVM resource Db : it is configuration data base , doesn’t have hierarchy like UVM config db so if one units some value to it , it can access by any where UVM config Db : it is configuration data base which inherit property from UVM resource DB also it has component hierarchy, higher in
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
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
Any questions related to any company might not be same , it is just to analyse your skill before attempting into Broadcom Lets Start What is cache coherency protocol What is set associative mapping and how is it designed ? What is DPI function , do have idea how to use it ? What are
Welcome to section uvm question and answer part , I will try to put around 20 to 30 questions and answer related to UVM Lets Start What is a virtual sequence and where do we use a virtual sequence? What are its benefits? company favorite question A virtual sequence is a sequence which controls stimulus
