FPGAs: What makes them programmable?

It sounds crazy when you say there is a device called FPGA that might replace ASIC. Definitely it will be a great achievement for the electronics engineers if they can make a hardware which can be used for all the electronic devices. Field Programmable Gate Array (FPGA) specifies that  it can be configured by costumer or designer after manufacturing. Hardware description languages (HDLs), such as VHDL and Verilog are used to implement the logic.

FPGA

FPGAs have mainly four elements viz. CLBs, Interconnects, BRAMs and IOBs which makes them programmable.  Configurable Logic Blocks (CLBs) are the main weapons to make device programmable. CLBs are made up of LUTs, flip-flop and a 2:1 mux. 

FPGA

Look UP Tables (LUTs) are made up of small BRAMs that can implement any logic function. Each of inputs is essentially an address for the BRAM so that it can define the output logic to the block. 2 inputs LUT can become any logic gate. LUTs are then connected to the DFF which are the memory elements used to store the output from LUT. A 2:1 MUX is used in case you want to bypass the DFF (D-Flip-flop). Each logic block can connect through the Interconnects to their corresponding block to implement the desired logic. IOBs are used as an interface to the outer world.

Verilog Training in Delhi - NCR

Today, we had got the easiest approach for analyzing our hardware description circuit virtually before doing fabrication on PCB’s. Verilog is one of the weapons to resolve this problem and very interesting way to design our circuit. Verilog is one of the hardware description languages which are very easy to implement the desired functionality in the form of the virtual hardware circuit, but we have also had options to check whether the design is working properly or not. Through the process of simulation, we can easily see that after providing inputs we are getting the desired output or not in the simulation window. We can easily see the wide range of Verilog applications. Verilog is not only simply the hardware descriptive language, but one of the easiest approaches for designing task regarding any fields such as communications, digital signal processing or simply mathematics. The ones we come to know, what task we have to perform, it doesn’t matter to which field it is related we can design the whole package on a just small piece of silicon by just writing few Verilog lines.

VLSI Projects

Very Large Scale Integration (VLSI) describes about the semiconductor integrated circuits which are composed of hundreds of thousands of transistors in a chip. It provides high computational speed with minimum power dissipation, minimum chip area and lower cost. Frontend and Backend domain contains all the design steps of a VLSI chip from system level to layout level. SiliconMentor is the innovative technical group that works in both domains to cover the vast field of VLSI. According to the MRD, a new VLSI chip idea built up for the people requirements. This idea propagates to Frontend technical teams and they start implementation of the project using HDLs. They design RTL level and logic level of the required project. After that Frontend verification is required to check the design specifications using System Verilog. If it passes all the verification successfully then the project further propagates to the Backend group. They perform their task from circuit level to the layout level using various tools such as Cadence Virtuoso, Tanner, and ADS etc.  And verification at backend level is also required to check that specifications. So according to requirements, we have various VLSI project domains such as Digital, Analog VLSI projects, DSP VLSI projects , Communication VLSI projects  and FPGA in  Frontend and Backend projects. SiliconMentor project guidance covers Verilog and System Verilog language, tools like Model_sim, Questa_sim, Xilinx ISE, MATLAB Simulink, Tanner (S-edit, L-edit), ADS, H-Spice, P-Spice, Cadence Orcad and Micro wind. SiliconMentor also works at sub-device level using COMSOL Multiphysics.

Need for IEEE VLSI Projects

IEEE (Institute of Electrical and Electronics Engineers) is an advanced innovation and technical group of engineers, scientists, developers, physicists, medical doctors and researchers around the world. It has established on 1^st  January, 1963 with the merging of societies AIEE (American Institute of Electrical Engineers) and IRE (Institute of Radio Engineers). IEEE is the world’s largest technical professional association which has now many fields such as electronic, electrical, communication, computing, nanotechnology, bioengineering and robotics. Now IEEE serves 38 societies, transactions, 130 journals and 300 conferences anually. IEEE prefers exact experimental research in specific areas. Research is most important for the student, researcher, professor and engineer. Without research, all those has nothing new to deliver to the world. Studies after the graduation means research. 21^st centuries research is mainly focused on electronics because modern technological world,involves electronics to make things smart and fast. VLSI (Very Large Scale Integration) is the core domain of electronic semiconductor circuits. IEEE research in VLSI is the need of electronic world. Electronics can not move further without a research in VLSI.So IEEE VLSI projects and research papers are needed for the M.Tech and Ph.D students. VLSI is most innovative and interesting field in electronics. VLSI has mainly two types of design steps: Frontend and Backend. In frontend, we design the system and RTL level using HDLs according to the specification of projects or IC and in backend, we design logic, circuit and layout level of the projects. M.Tech, Ph.D and industrial VLSI projects should be new technological oriented to create new electronics world for the upcoming generation.

Design a Single Precision Floating Point Unit

A single precision floating point unit in verilog is introduced. The novelty of a single precision floating point unit is to provide five arithmetic operations: addition, subtraction, multiplication, division, and square root. In top-down design approach, four arithmetic modules: addition/subtraction, multiplication, division, and square root are combined to form a single precision floating point unit. Each module is independent from each other. The modules are realized and validated using verilog simulation in the Modelsim SE 6.5 and synthesis using Xlinx ISE Design Suite 13.3.

The single precision floating point unit implemented, is a 32-bits processing unit which allows arithmetic operations on a floating point numbers. The floating point unit complies fully with IEEE 754 standard.
