Design Using CIF Code MCQ Quiz – Objective Question with Answer for Design Using CIF Code

1. Caltech intermediate form code is a

A. low-level graphic language
B. low-level textual language
C. high-level graphic language
D. high-level textual language

Caltech intermediate form code is a low-level graphic language used to specify the geometry of integrated circuits.

2. CIF generates code that is

A. high-level language
B. assembly level language
D. very high-level language

CIF code is to communicate chip geometry in a standard machine-readable form for mask-making.

3. CIF code is compatible with

A. low system geometry
B. large system geometry
C. both low and large system geometry
D. medium system geometry

CIF code is reasonably compact and can cope with both low and large system geometry. It is easily readable.

4. Design through CIF is done using

A. color codes
B. geometric shapes
C. different layer thickness
D. transistors

In Caltech intermediate form code, the design is given using geometric shapes. Boxes, polygons, and wires are readily defined.

5. The CIF dimensions are given in the form of

A. X, Y coordinates
B. lambda form
C. millimeter form
D. alpha form

The CIF dimensions and positions are given in X, Y coordinate form but are in absolute dimension units and not in lambda form.

6. Polygons in CIF are specified in terms of

A. length
B. width
C. vertices
D. angles

In CIF, polygons(P) are specified in terms of vertices in order. An n-sided polygon needs n vertices and a connection between first and last.

7. Wires are specified in terms of

A. vertices
B. width
C. angles
D. lengths

Wires(W) are specified in terms of their width followed by the center line’s coordinates of the wire’s path.

8. CIF can also accommodate rotations and translations.

A. true
B. false

CIF also accommodates cells and rotations and translations etc along with geometrically shaped designs.

9. If the vector coordinate is (1,0) it indicates that

A. length is parallel to the y-axis
B. length is parallel to the x-axis
C. width is parallel to the y-axis
D. width is parallel to the x-axis

If the vector coordinate is (1,0), it denotes that the length will be parallel to the x-axis. The direction is always assumed parallel to the length.

10. In which layer do the geometrical structures exist?

A. metal
B. silicon
C. silicide
D. diffusion
