How do I block comments on Verilog?
How do I block comments on Verilog?
Vera supports two types of comments as in Verilog and C language. A single-line comment starts with a double slash (//) and finishes out the line. A block statement starts with a /* and ends with a */. Everything between the start and end tags is a comment.
What is the correct syntax for writing numbers in Verilog?
Verilog Number Format. The consist of an apostrophe ( ‘ ) followed by b (binary, base-2), d (decimal, base-10), o (octal, base-8) or h (hexadecimal, base-16) for integer numbers.
What is the use of System Verilog?
SystemVerilog, standardized as IEEE 1800, is a hardware description and hardware verification language used to model, design, simulate, test and implement electronic systems.
What is comment and uncomment?
To uncomment something means to remove the characters that makes it a comment. “Comment out” means to use comment syntax to remove something from the parsed code. “Uncomment” is the reverse operation. They are both the correct expression for their respective referents.
How do I block comments in Java?
To comment a block:
- Select the required block of code.
- Press Ctrl + Shift + / The beginning (/*) and ending (*/) characters will be added in the appropriate places in order to mark the selected block as a comment.
Is UVM is independent of SystemVerilog?
Is UVM independent of SystemVerilog? No. UVM is built on SystemVerilog and hence you cannot run UVM with any tool that does not support SystemVerilog.
How do you trigger an event in SystemVerilog?
How to trigger and wait for an event?
- Named events can be triggered using -> or ->> operator.
- Processes can wait for an event using @ operator or .triggered.
What does Z mean in Verilog?
high-impedance state
The SystemVerilog value set consists of the following four basic values: 0—represents a logic zero or a false condition 1—represents a logic one or a true condition x—represents an unknown logic value z—represents a high-impedance state The values 0 and 1 are logical complements of one another.
Is SystemVerilog better than Verilog?
SystemVerilog acts as a superset of Verilog with a lot extensions to Verilog language in 2005 and became IEEE standard 1800 and again updated in 2012 as IEEE 1800-2012 standard….Difference between Verilog and SystemVerilog :
| S.No. | VERILOG | SYSTEMVERILOG |
|---|---|---|
| 04. | Verilog is based on module level testbench. | SystemVerilog is based on class level testbench. |
How do you write a comment in Verilog?
There are two ways to write comments in Verilog. A single line comment starts with // and tells Verilog compiler to treat everything after this point to the end of the line as a comment. A multiple-line comment starts with /* and ends with */ and cannot be nested.
What is var_a and var_a in Verilog?
Verilog is case-sensitive, so var_a and var_A are different. There are two ways to write comments in Verilog. A single line comment starts with // and tells Verilog compiler to treat everything after this point to the end of the line as a comment. A multiple-line comment starts with /* and ends with */ and cannot be nested.
What are SystemVerilog procedural statements?
Verilog procedural statements are in initial or always blocks, tasks, or functions. SystemVerilog adds a final block that executes at the end of simulation.SystemVerilog final blocks execute in an arbitrary but deterministic sequential order. This is possible because final blocks are limited to the legal set of statements allowed for functions.
What are always_comb and always_latch blocks in SystemVerilog?
To avoid this mistake, SystemVerilog adds specialized always_comb and always_latch blocks, which indicate design intent to simulation, synthesis, and formal verification tools. SystemVerilog also adds an always_ff block to indicate sequential logic.
