This set of Embedded Systems Multiple Choice Questions & Answers (MCQs) focuses on “Verilog and System Verilog in Embedded Systems”.
1. Which of the following is standardised as IEEE 1364?
a) C
b) C++
c) FORTRAN
d) Verilog
View Answer
Explanation: The Verilog is a hardware description language which was developed for modelling hardware and electronic devices. This was later standardised by IEEE standard 1364.
2. Who developed the Verilog?
a) Moorby
b) Thomas
c) Russell and Ritchie
d) Moorby and Thomson
View Answer
Explanation: The Verilog is a hardware description language which was developed by Moorby and Thomson in 1991 and it was standardised as IEEE standard 1364. The Verilog is modelled for the electronics devices.
3. Which versions of the Verilog is known as System Verilog?
a) Verilog version 3.0
b) Verilog version 1.0
c) Verilog version 1.5
d) Verilog version 4.0
View Answer
Explanation: The Verilog versions 3.0 and 3.1 is called as the System Verilog. These include several extensions to the Verilog version 2.0.
4. Which of the following is a Verilog version 1.0?
a) IEEE standard 1394-1995
b) IEEE standard 1364-1995
c) IEEE standard 1394-2001
d) IEEE standard 1364-2001
View Answer
Explanation: The IEEE standard 1364-1995 is the first version of the Verilog and IEEE standard 1394-2001 is the Verilog version 2.0.
5. Which of the following provides multiple-valued logic with eight signal strength?
a) Verilog
b) VHDL
c) C
d) C++
View Answer
Explanation: The Verilog supports the multiple-valued logic with eight different signal strength but Verilog is less flexible compared to the VHDL, that is, it allows the hardware entities to be instantiated in loops which help to build up a structural description.
6. Which of the following is a superset of Verilog?
a) Verilog
b) VHDL
c) System Verilog
d) System VHDL
View Answer
Explanation: The System Verilog is a superset of the Verilog. But later on, System Verilog and Verilog has merged into a new IEEE standard 1800-2009.
7. Which hardware description language is more flexible?
a) VHDL
b) Verilog
c) C
d) C++
View Answer
Explanation: The Verilog is less flexible compared to the VHDL, that is, it allows the hardware entities to be instantiated in loops which help to build up a structural description. But Verilog, on the other hand, focuses more on the built-in features.
8. Which of the following provide more features for transistor-level descriptions?
a) C++
b) C
c) VHDL
d) Verilog
View Answer
Explanation: The Verilog offers more features than the VHDL but VHDL is more flexible compared to the Verilog. The Verilog can provide transistor-level descriptions but the VHDL cannot provide this description.
9. Which hardware description language is popular in the US?
a) System Verilog
b) System log
c) Verilog
d) VHDL
View Answer
Explanation: Verilog and VHDL are almost similar in their characteristics and have a similar number of users. The VHDL is more popular in Europe whereas Verilog is more popular in the US.
10. Which hardware description language is more popular in Europe?
a) VHDL
b) System log
c) Verilog
d) C
View Answer
Explanation: The Verilog and VHDL are hardware description language and these are similar in their characteristics and have a similar number of users. The VHDL is more popular in Europe. The Verilog is more popular in the US.
