VLSI Design Style MCQ Quiz – Objective Question with Answer for VLSI Design Style

1. In which design all circuitry and all interconnections are designed?

A. full custom design
B. semi-custom design
C. gate array design
D. transistor design

Answer: A

Full custom design is the complete design for the implementation. It contains all circuitry and all interconnections/communication paths.

 

2. Which design contains only the interconnections designed?

A. full custom design
B. semi-custom design
C. gate array design
D. transistor design

Answer: C

Gate array design which is also known as uncommitted logic array design has the design of only the interconnections/communication paths.

 

3. In which method regularity is used to reduce complexity?

A. random approach
B. hierarchical approach
C. algorithmic approach
D. semi-design approach

Answer: B

The hierarchical approach is the one in which principles of iteration or regularity can be used to reduce the complexity of the design task.

 

4. Size of the die is determined using

A. transistor size
B. inverter size
C. area of the circuitry
D. length of the circuitry

Answer: C

The size of the die is determined by the area occupied by the circuitry. Large die sizes are associated with poor yields and high costs.

 

5. Which design is faster?

A. full custom design
B. semi-custom design
C. gate array design
D. transistor design

Answer: C

Gate array design is faster than a prototype full-custom design and the final custom designs must be carefully optimized.

 

6. Which has relatively low-level capabilities?

A. hand-crafted designs
B. computer-assisted textual entry
C. computer-assisted graphical entry
D. silicon compiler-based design

Answer: B

Computer-assisted textual entry has programs that may be relatively low-level capabilities and it allows the entry of rectangular boxes, wires, etc.

 

7. Computer-assisted graphical entry is done through

A. monochrome
B. grayscale graphics
C. bichrome
D. trichrome

Answer: A

Computer-assisted graphical entry of mask geometry is through either monochrome or color graphics terminal.

 

8. Which method is used for verification along with generation?

A. hand-crafted designs
B. computer-assisted textual entry
C. computer-assisted graphical entry
D. silicon compiler-based design

Answer: C

Computer-assisted graphical entry method encourages regularity and is generally used with a generate then verify design philosophy.

 

9. Which method uses a high-level programming language?
A. hand-crafted designs
B. computer-assisted textual entry
C. computer-assisted graphical entry
D. silicon compiler-based design

Answer: D

Silicon compiler-based design uses a high-level approach and uses special languages like high-level language compilers.

 

10. The set of design rules does not give

A. widths
B. spacing
C. colors
D. overlaps

Answer: C

Communication between the fabrication house and the designer takes the form of a set of design rules with gives clearance, widths, spacing, overlaps, etc.
