111. Which of the following is an analogue extension of the VHDL?
A. VHDL-AMS
B. System VHDL
C. Verilog
D. System Verilog
Answer: A
The VHDL-AMS is the extension of the VHDL and this includes the analogue and mixed behaviour of the signals.
12. Which of the following support the modelling partial differentiation equation?
A. gate level
B. algorithmic level
C. system level
D. switch level
Answer: C
There are a variety of levels for designing the embedded systems and each level has its own language. The system level is one such kind which has many peculiarities concerning the other levels. The system model denotes the entire embedded system and includes the mechanical as well as the information processing aspects. This also supports the modelling of the partial differential equations, which is a key requirement in the modelling.
13. Which level simulates the algorithms that are used within the embedded systems?
A. gate level
B. circuit level
C. switch level
D. algorithmic level
Answer: D
The algorithmic level simulates the algorithm which is used within the embedded system.
14. Which level model components like ALU, memories registers, muxes and decoders?
A. switch level
B. register-transfer level
C. gate level
D. circuit level
Answer: B
The register-transfer level modelling models all the components like the arithmetic and logical unit(ALU), memories, registers, muxes, decoders etc and this modelling is always cycled truly.
15. Which of the following is the most frequently used circuit-level model?
A. SPICE
B. VHDL
C. Verilog
D. System Verilog
Answer: A
The SPICE is a simulation program with integrated circuit emphasis, which is a frequently used circuit level in the early days. It is used to find the behaviour and the integrity of the circuit.
16. Which model includes geometric information?
A. switch-level model
B. layout model
C. gate-level model
D. register-transfer level
Answer: B
The layout reflects the actual circuit model. It includes geometric information and cannot be simulated directly since it does not provide information regarding the behaviour.
17. Which model cannot simulate directly?
A. circuit level model
B. switch-level model
C. gate-level model
D. layout model
Answer: D
The layout model reflects the actual circuit model and this includes the geometric information this model cannot be simulated directly because it does not provide the information regarding the behaviour.
18. Which of the following models are the components like resistors, capacitors etc?
A. register-transfer level
B. layout model
C. circuit level model
D. switch-level model
Answer: C
The circuit-level model simulation is used for the circuit theory and its components such as resistors, inductors, capacitors, voltage sources, and current sources. This simulation also involves partial differential equations.
19. Which model uses transistors as its basic components?
A. switch model
B. gate level
C. circuit level
D. layout model
Answer: A
The switch model can be used in the simulation of the transistors since the transistor is the very basic component of a switch. It is capable of reflecting bidirectional transferring of the information.
20. Which model is used to denote the Boolean functions?
A. switch level
B. gate-level model
C. circuit level
D. layout model
Answer: B
The gate-level model is used to denote the boolean functions and the simulation only considers the behaviour of the gate.
21. Which model is used for the power estimation?
A. gate-level model
B. layout model
C. circuit model
D. switch model
Answer: A
The gate-level model is used to denote the boolean functions and the simulation only considers the behaviour of the gate. This model is also useful in power estimation since it provides accurate information about the signal transition probabilities.
22. In which model, the effect of instruction is simulated and their timing is not considered?
A. gate-level model
B. circuit model
C. coarse-grained model
D. layout model
Answer: C
The coarse-grained model is a kind of instruction set level modelling in which only the effect of instruction is simulated and the timing is not considered. The information which is provided in the manual is sufficient for this type of modelling.
23. Which models communicate between the components?
A. transaction-level modelling
B. fine-grained modelling
C. coarse-grained modelling
D. circuit level model
Answer: A
The transaction-level modelling is a type of instruction set level model. This modelling helps in the modelling of components which is used for communication purpose. It also models the transaction, such as read and write cycles.
24. Which of the following has a cycle-true set of simulations?
A. switch-level model
B. layout model
C. circuit-level
D. fine-grained model
Answer: D
The fine-grained model has the cycle-true instruction set simulation. In this modelling, it is possible to compute the exact number of clock cycles which is required to run an application.
