Written Test Mentor Graphics exam was completely a subjective one. The questions asked can be put under 3 headings: 1. C [ long questions. Difficult.  ] 2. Analytical questions [Medium difficulty level] 3. Digital Design [comparatively easy questions] All the questions were SUBJECTIVE ! Interview More interested in students who are good at data structures. And Of course you know in EDA tool...

First things first. The Profile It said R & D engineer. Sounds terrific, right? But don't know what they placed for. At the interview level they asked only puzzles or ( some "chit chatting" according to my batchmates) They placed students ( only 1 from VLSI ) to work on their emulators for FPGAs. If you are thinking what are emulators now, just...

Written Test Profile : Digital Design Engineer Pattern : Completely Subjective. Application level questions.       1. Given a buffer. When an input pulse of 100Mhz with 50% duty cycle is applied, the output is having a duty cycle of 60%. What is the output duty cycle if the input frequency is 50Mhz. [ assume delay of bnuffer is independent of freq ]...

Xilinx System Generator provides a set of Simulink blocks (models) for several hardware operations that could be implemented on various Xilinx FPGAs. These blocks can be used to simulate the functionality of the hardware system using Simulink environment. The nature of most DSP applications requires floating point format for data representation. While this is easy to implement on several computer systems running high...

1. Sequential block with blocking assignments The statements in a sequential block are processed in the order they are specified. A statement is executed only after its preceding statement completes execution. If delay or event control is specified, it is relative to the simulation time when the previous statement in the block completed execution. 2. Sequential block with non-blocking assignments If no regular...

Here we will be talking about the subjects that are normally not included in the curriculum for Microelectronics and VLSI Design people, yet important for them as their job life progresses. 1. Computer Organisation and Architecture Computer architecture is a set of disciplines that describe the functionality, organization and implementation of computer systems. Some definitions of architecture define it as describing the capabilities and...
