UVM is a standardized methodology for verifying complex IP and SOC in the semiconductor industry. UVM is an Accellera standard and developed with support from multiple vendors Aldec, Cadence, Mentor, and Synopsys. UVM 1.0 was released on 28 Feb 2011 which is widely accepted by verification Engineer across the world. UVM has evolved and undergone a series of minor releases, which introduced new features.
UVM provides the standard structure for creating test-bench and UVCs. The following features are provided by UVM
• Separation of tests from test bench
• Transaction-level communication (TLM)
• Sequences
• Factory and configuration
• Message reporting
• End-of-test mechanism
• Register layer
The System Verilog UVM promises to improve verification productivity while enabling teams to share tests and test benches between projects and divisions. This promise can be achieved; the UVM is a powerful methodology for using constrained randomization to reach higher functional coverage goals and to explore combinations of tests without having to write each one individually. Unfortunately the UVM promise can be hard to reach without training, practice and some significant expertise. Verification is one of the most important activities in the flow of ASIC/VLSI design. Verification consumes large amount of design flow cycle & efforts to ensure design is bug free. Hence it becomes intense requirement for powerful and reusable methodology for verification.

Developed by ITU-T, ISDN is a set of protocols that combines digital telephony and data transport services to digitise the telephone network to permit the transmission of audio, video and text over existing telephone line. ISDN is an effort to standardise subscriber services, provide user or network interface and facilitate the inter-networking capabilities of existing voice and data networks. The goal of ISDN is to form a wide area network that provides universal end-to-end connectivity over digital media by integrating separate transmission services into one without adding new links or subscriber links.

In present era, the scopes of information technology growing with a very fast .We do not see any are untouched from this industry. The scope of information technology has become wider includes: Business and industry. Household Business, Communication, Education, Entertainment, Science, Medicine, Engineering, Distance Learning, Weather Forecasting. Carrier Searching and so on.
My project named “Event Management System” is software that store and maintained all events coordinated in college. It also helpful to print related reports. My project will help to record the events coordinated by faculties with their Name, Event subject, date & details in an efficient & effective ways.
In my system we have to make a system by which a user can record all events coordinated by a particular faculty. In our proposed system some more featured are added which differs it from the existing system such as security.

10. Definitions
• What is a compiler?
– A program that accepts as input a program text in a certain language and
produces as output a program text in another language, while preserving the
meaning of that text (Grune et al, 2000).
– A program that reads a program written in one language (source language)
and translates it into an equivalent program in another language (target
language) (Aho et al)
– Report errors of source language which are detected during the
8-Jan-15 CS346 Lecture 1 10
– Report errors of source language which are detected during the
translation process
• What is an interpreter?
– A program that reads a source program and produces the results of executing
this source.
• We deal with compilers! Many of these issues arise with interpreters!

12. Examples
• C is typically compiled
• Lisp is typically interpreted
• Java is compiled to bytecodes, which are then interpreted
• source-to-source compiler, transcompiler, or transpiler :
– C++ to C
– High Performance Fortran (HPF) to Fortran (parallelising compiler)

– High Performance Fortran (HPF) to Fortran (parallelising compiler)
• Cross Compilers (wiki)
– A cross compiler is a compiler capable of
reading executable code for a platform other than the one on
which the compiler is running. For example, a compiler that runs
on a Windows 7 PC but generates code that runs
on Android Smartphone is a cross compiler.

13. Qualities of a Good Compiler
What qualities would you want in a compiler?
– generates correct code (first and foremost!)
– generates fast code
– conforms to the specifications of the input language
– copes with essentially arbitrary input size, variables,
8-Jan-15 13
– copes with essentially arbitrary input size, variables,
etc.
– compilation time (linearly)proportional to size of source
– good diagnostics
– consistent optimisations
– works well with the debugger
CS346 Lecture 1
14. Principles of Compilation
The compiler must:
• preserve the meaning of the program being compiled.
• “improve” the source code in some way.
Other issues (depending on the setting):
8-Jan-15 14
Other issues (depending on the setting):
• Speed (of compiled code)
• Space (size of compiled code)
• Feedback (information provided to the user)
• Debugging (transformations obscure the relationship source code vs target)
• Compilation time efficiency (fast or slow compiler?)
CS346 Lecture 1
15. Applications
• Most common use: translate a high-level program to object code
– Program Translation: binary translation, hardware synthesis, …
• Optimizations for computer architectures:
– Improve program performance, take into account hardware parallelism, etc…
• Interpreters: e.g., BASIC, Lisp etc.
8-Jan-15 15
• Software productivity tools
– Debugging aids: e.g., purify
• Text formatters, just-in-time compilation for Java, power
management, global distributed computing, …
Key: Ability to extract properties of a source program (analysis) and
transform it to construct a target program (synthesis)
