    1.Profileof the company:

    String technologies, a training division of Unistring Tech Solutions Pvt Ltd, a pioneer in VLSI and Embedded systems training. Every year we train more than 200 M tech students (VLSI / Embedded / DSP) and about 1000 B Tech Electronics students on various core modules. A good no of our students are working with many Core companies. We conduct about 50 to 60 on site training programs and faculty development programs at engineering colleges. We have an expert team of trainers rich with hardware and software development skills. Team has exposure in working on ARM, 8051, PIC, PSOC, AVR, Controllers and FPGAhardware development and embedded software development. The following is the list of some esteemed colleges with  which  we have MOUs. Sreenidhi engineering college,  Mallareddy Group of Institutions, Gudlavalleru College of Engineering,  BVRIT. Etc. This list has more than 50 engineering colleges.

    2. Initiative:

    We have a close association with many core companies and support the companies in recruitment by conducting core placement drives. Based on the latest interactions with many companies in and around Hyderabad and Bangalore, we understood some recruitment requirements. The companies are willing to recruit the fresh graduate and undergraduate students with some core skill set.  In order to reach more number of students and to find the students who can meet industry requirements we have initiated this online training program.

    3. Solution:

    The solution to the current recruitment problem  is  to improve the employability skills of the students  through a practical approach. In order achieve this objective we have come up with a oncampus online training model to the final year ECE , EEE, EIE  and CSE students.

    3. 1 Why Online Campus training :
    • Students need not travel longer distances and need not stay at the outstation to get expert training and hands on experience.
    Experts can do a better job as they need not  travel to the remote places
    • College faculty has better supervision and monitoring on the students.
    • Better infrastructure in the college will be properly utilized.
    • This model will be more economical to the students.
    • Costly Embedded and FPGA boards can be made available over virtual lab setup to all students
    • With present internet technology perfect connectivity is possible including video of speaker, computer screen and complete lab tools & hardware access.

    3. 2 How is this different than on campus training ? Trainers are the Technologists, experts from the industries and scientists from the reputed R & D organizations with over 10 years of Experience.
    • In present day scenario, typical on campus trainings, will be done by inexperienced engineers. It is a known fact that no industry expert would visit the college campus months together. Hence the online training is the only viable solution.
    • Focus is more on getting the development done through the students not on giving direct solutions to the problem. Please note that this programme has more than 50% sessions lab and assignments.
    • Dedicated and Committed team with exclusive focus on improving the skills of the students
    • Focus is not just to complete the training/ project.

    4. Course Duration:

    Sl no





    Number of weeks




    No of day in a week




    No of hours per day




    Total no of hours



    Course begins from 1st January 2013.

    Each and every student shall spend 3 hours per day under our supervision. The student side commitment is compulsory. Students with less than 90% attendanceor 50% marks in our lab sessions will not be processed by our HR team for placements.

    5. Execution Model :

    Under this model Computers in the college will be installed with online broadcast software. College requiresto arrange a class room with sufficient seating capacity and LCD projector. In case of lecture sessions the speakers video and computer screen is streamed to class room, which will be projected on screen with LCD. The students video shall appear on the computer screen at speakers place. This ensures perfect one to one connectivity making live interaction possible.
    From String technologies experts will be connected online and the computer screen will be shared. Face of the instructor is visible to the student along with the content to be explained.

    5.1 Online black board :

    Expert will use latest computer connected notepad tools which will be used to explain the content as it is explained in black board of the class room.

    5.2 Online Hardware Access :( Revolutionary idea to bring the complex hardware accessible to Engineering institutions)

    All the hardware used for training will also be shared online , so that each student will have access to the hardware simultaneously. This enables the students not only listing to the classes by experts, it will also enable the students to practice the content effectively.

    5. 3 Other important points

    • Sessions from Technology Experts will be delivered on line. Students shall clarify the doubts online live during the session through Voice and chat.
    • Provision to access the hardware remotely and develop the applications will be provided.
    • Students will be guided online to use the hardware.
    • Every doubt and question will be resolved instantly.
    • Complete hands on experience in using the hardware.
    • No wastage of time in travelling.
    • Effective utilization of time, value for money and time.

      5. 4 Deliberate practice:
    • This program is aimed at making the students solve the problems on their own through rigorous practice and own analysis.
    • Nospoon feeding , Only providing the necessary content
    • Regular tests will be conducted to monitor the improvements of the students.
    • Depending on the test results more practice problems will be given to improve the specific skills. That is the target of deliberate practice.
    • Program is aimed at making the students solve the industry level problems on their own.

    5. 5 Infrastructure needed at the college:

    • PC with  internet connectivity (as many  no of PCs  as the number of students)
    • Audio system connected to the internet PC.
    • Wireless mike to interact with the Experts.
    • Class room with LCD projector
    • One Webcam (2 Megapixel or above)
    • Internet connectivity 2 Mbps broadband
    • One coordinator to look after the connectivity  and training progress.
    • Lab with Personal computers all with internet connectivity (2 Mbps shared among all PCs)

    An engineer from String Technologies shall visit the college to establish the initial setup and train the computer administrator of college about the maintenance.

    6  Financial model :

    • Fee for the 12 weeks training is INR 5000/.
    • Min 20 students per stream ( VLSI / Embedded).
    • This payment shall be done at the beginning of the course.
    On placement, individual shall pay the salary of the first month to String technologies

    7 Target industries :

    Category 1 : Industry working on design and development and realization of the embedded hardware
    Category 2 : Companies working on Embedded software protocol development
    Category 3 : Companies working in IP core and algorithm development on FPGAs and High end processors.

    7 Course Content :

    • Initial part of the program is mandatory to all as mentioned in the stream column of the table below.
    • Rest of the coursecontent  isorganized in two streams one is VLSI and the other is Embedded.
      • Students opted for VLSI will be trained in the modules mentioned as VLSI .
      • Students opted for Embedded will be trained in the module mentioned as Embedded.
      • Modules mentioned as optional will be trained based on the industry requirements.
    • Students are free to choose the domain of interest.
