Solution:

What will be the values of the following variables after the REM operations?

`x = 5 REM 3; y = -5 REM 3; z = 5 REM -3;`

x = 2, y = -2 and z = -2

x = 2, y = 1 and z = -2

x = 2, y = -2 and z = 1

GENERIC (type : name <= initial_value);

Solution:

In the VHDL code given below, what will be the error at the time of compilation?

`TYPE my_int IS INTEGER RANGE -32 TO 32; TYPE other_int IS INTEGER RANGE 0 TO 100; SIGNAL x : my_int; SIGNAL y : other_int; y <= x + 2;`

Type mismatch

Syntax problem

No declaration

Can't compile

Solution:

LIBRARY package_name.parts;

LIBRARY library_name;

USE library_name;

LIBRARY library_name.package_name.parts

LIBRARY library_name;

USE library_name.package_name.parts

Solution:

The structure or flow of a VHDL code is as follows:

Library Declaration > Entity Declaration > Architecture Declaration > Configurations

Comment on the presented flow above.

The flow is perfectly correct

The flow is incorrect

The flow has some blocks of code missing

Cannot be determined, the flow of a code is dynamic
