What are the operators in Verilog?
Operators
| Verilog Operator | Name | Functional Group |
|---|---|---|
| * / % | multiply divide modulus | arithmetic arithmetic arithmetic |
| + – | binary plus binary minus | arithmetic arithmetic |
| << >> | shift left shift right | shift shift |
| > >= < <= | greater than greater than or equal to less than less than or equal to | relational relational relational relational |
What is dataflow in Verilog?
Dataflow Modeling. Dataflow modeling provides the means of describing combinational circuits by their function rather than by their gate structure. Dataflow modeling uses a number of operators that act on operands to produce the desired results. Verilog HDL provides about 30 operator types.
How many operator types are available in Verilog?
Verilog Shift Operators There are two kinds of shift operators: Logical shift operators : << and >> Arithmetic shift operators : <<< and >>>
What is data flow abstraction in Verilog?
Thus, we shift to the next level of abstraction in Verilog, Dataflow modeling. Dataflow modeling makes use of the functions that define the working of the circuit instead of its gate structure. This approach allows the designer to focus on optimizing the circuit in terms of the flow of data.
Which of the following operators are supported by Verilog?
Operators in Verilog
- Arithmetic operators.
- Logical Operators.
- Bit-wise Operators.
- Reduction Operators.
- Difference between logical, bitwise logical, and reduction operators?
- Relational operators.
- Equality Operator.
- Shift Operators.
What does the XOR operator do?
XOR is a bitwise operator, and it stands for “exclusive or.” It performs logical operation. If input bits are the same, then the output will be false(0) else true(1).
What is data flow model?
A data flow model is diagramatic representation of the flow and exchange of information within a system. Data flow models are used to graphically represent the flow of data in an information system by describing the processes involved in transferring data from input to file storage and reports generation.
What is data flow style?
In data flow architecture, the whole software system is seen as a series of transformations on consecutive pieces or set of input data, where data and operations are independent of each other. The data can be flown in the graph topology with cycles, in a linear structure without cycles, or in a tree type structure.
Which operators has highest precedence in Verilog?
Operator Precedence in Verilog
| Precedence | Operators | Operator Symbols |
|---|---|---|
| Highest | Unary Multiply Divide, Modulus | + – ! ~ * / % |
| Add Subtract Shift | + – << >> | |
| Relational Equality | < <= > >= == !== === !=== | |
| Reduction Logical | & ~& ^ ^~ | ~| && || |
What are the operators used for gates in data flow Modelling?
The gate-level modeling approach is suitable for smaller circuits and it’s more intuitive to a designer with basic knowledge of digital logic design….Data-flow Modeling, Operators and their Precendence in Verilog.
| Verilog Operator | Name | Functional Group |
|---|---|---|
| == != | case equality case inequality | equality equality |
| & ^ | | bit-wise AND bit-wise XOR bit-wise OR | bit-wise bit-wise bit-wise |
