What is conditional compilation in Verilog?
Verilog supports a few compiler directives that essentially direct the compiler to treat the code in a certain way.
What is conditional compilation explain with example?
#elif means “else if” and establishes an if else-if compilation chain. Amongst other things, #if provides an alternative method of “commenting out” code. For example, #if 0 printf(“#d”, total); #endif. Here, the compiler will ignore printf(“#d”, total); #ifdef and #ifndef.
What statements are used for conditional compilation?
The $ELSE statement is used in conjunction with the $IF statement to control conditional compilation. The $END statement is used in conjunction with the $IF statement to control conditional compilation. A $IF statement provides the means whereby selected parts of the source text are not included in the compilation.
What is conditional statement in Verilog?
This conditional statement is used to make a decision on whether the statements within the if block should be executed or not. If there is an else statement and expression is false then statements within the else block will be executed.
How does conditional compilation help a programmer?
In computer programming, conditional compilation is compilation implementing methods which allow the compiler to produce differences in the executable program produced and controlled by parameters that are provided during compilation.
What are the types of conditional statements in Verilog?
This conditional statement is used to decide whether certain statements will be executed or not….if-else-if
- // if statement without else part.
- if (expression)
- [statement]
- // if statement with an else part.
- if (expression)
- [statement]
- else.
- [statement]
When is the ‘assign’ statement used in Verilog?
Verilog assign Statement Assign statements are used to drive values on the net. And it is also used in Data Flow Modeling. Signals of type wire or a data type require the continuous assignment of a value. As long as the +5V battery is applied to one end of the wire, the component connected to the other end of the wire will get the required voltage.
How to prove a task in Verilog?
Tasks can be declared as automatic tasks as of Verilog 2001. task automatic do_write; Automatic is a term borrowed from C which allows the task to be re-entrant. A re-entrant task is one in which the items declared within the task are allocated upon every individual call of the task, as opposed to being shared between all calls of the task.
How does Verilog behave with negative numbers?
Behavioral level
How to get synthesizable delay in Verilog?
anyone have idea how to add a synthesizable deslay in verilog….. thanks Add a reply… However during backend phase delays can be incorporated by adding buffers /delay elements in the design.
