An overview of Research Guidance in PhD

Silicon Mentor is one of the best research entities in India. To make an environment of research we are providing our services in research and development of some of the world most recent burning topics in engineering and technology. Silicon Mentor has expertise in various research domain including Computer Vision, Machine Learning, VLSI, Biomedical Signal Processing and Digital Signal Processing. In the process of research and development we have a unit which provides research guidance to the PhD students. Our research process for PhD projects starts from the specific domain topic selection.

1)    The topic selection is based on either on the student requirement or we suggest them appropriate topic.
2)    After the selection of appropriate topic and research domain we assign our expert team for the support PhD student. This team works with the students on some of the previous work published in SCI indexed journals.
3)    During the review period of the previous work our team starts to generate new idea to modify the previous work.
4)    After the completion of previous work verification we turn our direction of research towards the modification in the previous design or to generate a new idea.
5)    For the implementation of new idea or modification we continuously contact the students and make him understand the new work.
6)    For the required tool training Silicon Mentor runs special class to train the students.
7)    After the modification of the design we do compare the result of the modified design and previous work.
8)    After the verification of complete verification of the result we forward this to next step.
9)    We do also compare analytical and simulative results for the preparation of the proposed method.
10)    After the completion of the all above steps we provide our expert team in the domain of research paper publication.
11)    Our expert team of Research paper publication provides updates about the new conference and journal publication.
12)    We usually suggest our clients to publish their work in IEEE, Springer like publications.
13)    We also help them to publish their work in any of the SCI index journals.

Thus we try to provide best research guidance for PhD thesis and PhD projects. We are in the process of continuous improvement to make our services more convenient in the area of Research and Development. For more information you can contact us.

How to make an FPGA Partially Reconfigurable

Partially reconfiguration means changing the FPGA partially or only the selected part of the FPGA is reconfigured. It can be done in two ways:

i)    Module based partial reconfiguration
Partial reconfiguration on the basis of difference

Module based partial reconfiguration:

In module based reconfiguration we reconfigure on the specific module or only by changing a selected module we can do the partially reconfiguration of our FPGA. The portions of the design to be reconfigured are known as reconfigurable modules. Specific properties and specific layout criteria must be met with respect to a reconfigurable module, FPGA design intending to use partial reconfiguration must be planned and laid out with that in mind.

Partial reconfiguration on the basis of difference:

Partial reconfiguration on the basis of difference is a method of making small changes in an FPGA design, such as changing I/O standards, LUT equations, and block RAM content.


i)    To lessen power or making the design power-efficient.
ii)    Through the JTRS Program, SDRs are becoming a reality for the defense industries as an effective and necessary tool for communication. SDRs assure the JTRS standard by having both a software-reprogrammable operating environment and the ability to support multiple channels and networks simultaneously.
iii)    Partial reconfiguration is useful in a variety of applications across many industries. The aerospace and defense industries have certainly taken advantage of its capabilities.
iv)    Increased system performance. Although a portion of the design is being reconfigured, the rest of the system can keep on to operate. There is no loss of performance or functionality with unaffected portions of a design.
v)    Hardware sharing. Because partial reconfiguration allows you to run multiple applications on a single FPGA, hardware sharing is realized. Benefits include reduced device count, reduced power consumption, smaller boards, and in particular lower costs.

key steps used in Xilinx to make the FPGA partially Reconfigured:

1: First Create Processor Hardware System.
2: Then Create Software Project.
3: After then Create a Plan ahead Project.
4: Defining a Reconfigurable Partition.
5: Adding Reconfigurable Modules.
6: significant the Reconfigurable Partition Region.
7: Running the Design Rule Checker.
 8: Then Create the First Configuration, Implementing, and Promoting.
9: Then Create Other Configurations, and Implementing.
10: Then Run Partial Reconfiguration to Verify Utility.
11: Generating Bit Files.
12: Creating an Image, and Testing.


There are many advantages to make the FPGA reconfigured. only some from them are following:

I)    To make the device more efficient.
II)    To lessen the LUTs of the design by replacing only specific portion.
III)    To lessen power of the design by replacing only specific portion.
IV)    To lessen the delay of the design by replacing only specific portion or a specific module.

Is It The Right Path To Pursue PhD Research?

PhD research is the highest level of academic research conducted in universities and institutes throughout the World. The methods used to conduct Ph.D. research are sound and the data that results from the research must be unique. There are many techniques has been created such as scientific methodologies have been created to ensure the soundness and uniqueness of doctoral research and to secure continuity in research results. The most often employed methodologies are quantitative methods, qualitative methods, comparative methods and clinical trials.

The world is producing a large number of PhD holders and their number is increasing every year. Therefore in this era how can a normal PhD holder can survive? World’s most population countries India and China producing more than 40,000 PhD every year. Most of the PhD has completed their research in a short duration which results in the quality of the graduates is not consistent. And Most of the PhD remains unemployed.

In our research whenever we think of doing the research we always think of  doing something innovative  which can change the world but when we come for real implementation of the idea we found only few things have done in our PhD research. The few things which done usually during PhD seems to be unique. What should we do? And, how to do? It depends on one’s circumstances but the research should contribute something new in the specific domain. 

Silicon Mentor is a place where many new researchers are working together to make something innovative and unique. These young researchers help the research students to pursue their research with some of the unique methodologies. Silicon Mentor have Expertise in different Domain such as Computer vision , Biomedical Research, Digital Signal Processing, Machine Learning , Low Power VLSI , Mixed Signal VLSI , FPGA implementation.
