What is synthesizable and non-synthesizable code?
Synthesizable Verilog is that subset of the language that are accepted by the synthesis tools. The non-synthesizable constructs are used only for simulation and the synthesis tool cannot handle them.
Is Synthesizable real?
The integer type is synthesizable, but real is not synthesizable.
What is synthesizable VHDL code?
VHDL is a very complete language, but only a subset of it can be used to write synthesizable code. During the synthesis process, the VHDL source code is translated into a circuit for a target technology such as an FPGA or an ASIC, using the appropriate library components.
What does synthesizable mean?
Filters. (chemistry) Able to be (easily) synthesized. adjective. 1.
Is always block synthesizable?
Basically every always block is describing a group of flip-flop, a group of latch, or a block of combinational circuit. Any always blocks that cannot be mapped to these three types of circuits are not synthesizable.
What is non-synthesizable code?
When you write you Verilog or VHDL code, you are writing code that will be translated into gates, registers, RAMs, etc. The program that performs this task is known as a Synthesis Tool. When you write code like this, it is called non-synthesizable code.
Is $clog2 synthesizable?
2 Answers. $clog2 is not supported by Verilog. It is a SystemVerilog system task. Moreover, system tasks are not synthesizable.
Which software is used for VHDL programming?
VHDL simulators
| Simulator name | License | Supported languages |
|---|---|---|
| FreeHDL | GPL2+ | VHDL-1987, VHDL-1993 |
| GHDL | GPL2+ | VHDL-1987, VHDL-1993, VHDL-2002, partial VHDL-2008 |
| Icarus Verilog | GPL2+ | |
| NVC | GPL-3.0-or-later | IEEE 1076-2002, VHDL-1993, subset of VHDL-2008 |
What is an example of synthesizing?
It’s simply a matter of making connections or putting things together. We synthesize information naturally to help others see the connections between things. For example, when you report to a friend the things that several other friends have said about a song or movie, you are engaging in synthesis.
Is always block sequential?
An always block is one of the procedural blocks in Verilog. Statements inside an always block are executed sequentially.
Why is initial block not synthesizable?
An initial block is not synthesizable and hence cannot be converted into a hardware schematic with digital elements. Hence initial blocks do not serve much purpose than to be used in simulations. These blocks are primarily used to initialize variables and drive design ports with specific values.
Which statement is Nonsynthesizable?
The statement which directly can be used to generate the Hardware called as Synthesizable statments. The statements which can’t make any hardware is known as Non-synthesizable.
