Question: What Is Elaboration In Synthesis?

What is elaboration time?

Elaboration is the process that occurs between parsing and simulation.

There is also a notion of time in simulation as evaluation proceeds by execution of process in a current time slot and moving on to next..

What is the difference between code compiled simulation and normal simulator?

Compiled Simulator : This kind of simulator converts the whole Verilog code into machine dependent code and then runs the simulation. … Compiled simulators are very fast. Interpreted Simulator : This kind of simulator executes line by line, thus is very slow compared to a compiled simulator.

What is race condition in SV?

A race condition in SystemVerilog is an simulation modeling artifact where the order of execution between two different constructs cannot be guaranteed.

Why do we synthesize?

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.

What is the difference between RTL and netlist?

RTL : Functionality of device written in language like Verilog, VHDL. Its called RTL if it can be synthesized that is it can be converted to gate level description. Netlist: You get a netlist after you synthesize a RTL. This is gate level description of the device.

What happens during elaboration?

Elaboration of a task variable creates, initializes, and runs the task. Elaboration happens each time a subprogram is called or a block is entered. … When the elaboration of a Library Unit results in the use of resources from another Library Unit, there is a potential for trouble.

What is synthesis and simulation?

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 is the difference between SystemVerilog packed and unpacked array?

In SystemVerilog packed array refers to the dimensions declared before the object name. The term unpacked array refers to the dimensions declared after the object name. A packed array is represented in a memory as a contiguous set of bits. …

What is RTL in VLSI?

In digital circuit design, register-transfer level (RTL) is a design abstraction which models a synchronous digital circuit in terms of the flow of digital signals (data) between hardware registers, and the logical operations performed on those signals.

What is elaboration in Verilog?

1364-2005: Elaboration is the process that occurs between parsing and simulation. It binds modules to module instances, builds the model hierarchy, computes parameter values, resolves hierarchical names, establishes net connectivit, and prepares all of this for simulation.

What is synthesis in VLSI?

Synthesis is the process of transforming your HDL design into a gate-level netlist, given all the specified constraints and optimization settings. Logic synthesis is the process of translating and mapping RTL code written in HDL (such as Verilog or VHDL ) into technology specific gate level representation.
