What is synthesize in Verilog?
Synthesis is the process of converting a high-level description of design (Verilog/VHDL) into an optimized gate-level representation. Logic synthesis uses a standard cell library which have simple cells, such as basic logic gates like AND, OR, and NOR, or macro cells, such as adder, muxes, memory, and flip-flops.
What is simulation and synthesis in Verilog?
Simulation is the execution of a model in the software environment. The test bench is used in ALDEC to simulate our design by specifying the inputs into the system. Synthesis is the process of translating a design description to another level of abstraction, i.e, from behaviour to structure.
What language is Verilog?
hardware description language
Verilog, standardized as IEEE 1364, is a hardware description language (HDL) used to model electronic systems. It is most commonly used in the design and verification of digital circuits at the register-transfer level of abstraction.
Why are delays cannot be synthesized in Verilog?
Synthesizing means somehow converting what you have described (in Verilog here) into real hardware. Now in your Verilog you say that you have a 50ns delay. Ok, but now, in term of hardware, how would you convert this into actual hardware?
What to keep in mind when writing Verilog code?
There are two important things to keep in mind when writing Verilog code: Just like in an actual circuit, some parts of Verilog code execute simultaneously, not sequentially or line-by-line as in a single-threaded software program. Not all Verilog constructs can be synthesized, or turned into an actual logic circuit.
Which is an example of a Verilog assign statement?
The verilog assign statement is typically used to continuously drive a signal of wire datatype and gets synthesized as combinational logic. Here are some more design examples using the assign statement.
What do you need to know about Verilog shift registers?
Verilog Shift Register Code Verilog is a hardware description language, or HDL, which means it can be used to describe actual logic circuit hardware. Because of this, there are several aspects of Verilog that are different from typical software programming languages. There are two important things to keep in mind when writing Verilog code:
