What is synthesis in HDL?

Synthesis converts Verilog HDL models of hardware down to gate-level implementations automatically and maps these into target technology. Synthesis also optimizes the design for a given set of constraints related to area and speed.

Is Verilog and VHDL same?

Both Verilog and VHDL are Hardware Description Languages (HDL). These languages help to describe hardware of digital system such as microprocessors, and flip-flops. Therefore, these languages are different from regular programming languages. VHDL is an older language whereas Verilog is the latest language.

What is synthesis and simulation in HDL?

Definition. Simulation is the process of describing the behaviour of the circuit using input signals, output signals and delays. But, synthesis is the process of constructing a physical system from an abstract description using a predefined set of building blocks.

What is a module in HDL?

Modules can be used to represent hardware components by describing the hardware interface and behaviour, or can be used to declare parameters, tasks and functions that are used elsewhere in the design. The keyword macromodule is a synonym for module.

Is HDL a programming language?

Hardware description language (HDL) is a specialized computer language used to program electronic and digital logic circuits. The structure, operation and design of the circuits are programmable using HDL.

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.

Is HDL worth learning?

Yes it is worth it if you are creating FPGA and/or ASIC designs. VHDL is going to be with us for the long term. It covers simulation, synthesis and verification without the need for a separate verification language. As such it is more economical to buy fully capable VHDL tools.
