This set of Embedded Systems Multiple Choice Questions & Answers (MCQs) focuses on “Introduction to VHDL-II”.
1. How many kinds of wait statements are available in the VHDL design?
a) 3
b) 4
c) 5
d) 6
View Answer
Explanation: There are four kinds of wait statements. These are wait on, wait for, wait until and wait.
2. Which wait statement does follow a condition?
a) wait for
b) wait until
c) wait
d) wait on
View Answer
Explanation: The wait until follows a condition. The condition may be an arithmetic or logical one and the wait for statement follows time duration, it might be in microseconds or nanoseconds or any other time unit. Similarly, the wait on statement follows a signal list and the wait statement suspends indefinitely.
3. Which wait statement does follow duration?
a) wait for
b) wait
c) wait until
d) wait on
View Answer
Explanation: The wait for statement follows time duration, it might be in microseconds or nanoseconds or any other time unit.
4. Which of the following is a C++ class library?
a) C++
b) C
c) JAVA
d) SystemC
View Answer
Explanation: System C is a C++ class library which helps in solving the behavioural, resolution, simulation time problems.
5. Which model of SystemC uses floating point numbers to denote time?
a) SystemC 1.0
b) SystemC 2.0
c) SystemC 3.0
d) SystemC 4.0
View Answer
Explanation: The SystemC includes several models of the time units. SystemC 1.0 uses floating point numbers which denote time.
6. Which model of SystemC uses the integer number to define time?
a) SystemC 1.0
b) SystemC 2.0
c) SystemC 3.0
d) SystemC 4.0
View Answer
Explanation: The SystemC includes several models of the time. System 2.0 is an integer model to define time and this model also supports physical units such as microseconds, nanoseconds, picoseconds etc.
7. Which model of the SystemC helps in the communication purpose?
a) SystemC 2.0
b) SystemC 3.0
c) SystemC 1.0
d) SystemC 4.0
View Answer
Explanation: The SystemC 2.0 provides the channel port and interface ports for the communication purpose.
8. Which C++ class is similar to the hardware description language like VHDL?
a) SystemC
b) Verilog
c) C
d) JAVA
View Answer
Explanation: The SystemC is a C++ class which is similar to the hardware description languages like VHDL and Verilog. The execution and simulation time in the SystemC is almost similar to the VHDL.
9. What does ESL stand for?
a) EEPROM system level
b) Electronic-system level
c) Electrical system level
d) Electron system level
View Answer
Explanation: The ESL is electronic-system level and the SystemC is associated with the ESL and TLM. The SystemC is also applied to the architectural exploration, performance modelling, software development and so on.
10. What to TLM stand for?
a) transfer level modelling
b) triode level modelling
c) transaction level modelling
d) transistor level modelling
View Answer
Explanation: The TLM is transaction-level modelling and the SystemC is associated with the ESL and TLM.
