طراحی مدولاتور سیگما دلتا با استفاده از مدل رفتاری و شبیه سازی آن با vhdl - ams

در این پژوهش، مدلسازی رفتاری مدولاتور کلید-خازنی بوسیله زبان توصیف سخت افزار vhdl – amsانجام شده است. این موضوع از آن جهت اهمیت دارد که مدولاتور سیگما - دلتا اصلی ترین بخش در مبدل داده های آنالوگ به دیجیتال و همچنین دیجیتال به آنالوگ فرانمونه برداری است. با وجود اینکه شبیه سازی در سطح ترانزیستوری خیلی دقیق تر است ولی بعلت زمان بسیار زیادی که محاسبات در این سطح طول می کشد این روش برای سیستم های ...

VHDL Concepts

This paper presents a formal model of several fundamental concepts in VHDL including the semantics of individual concurrent statements, and groups of those statements, resolution functions, delta delays, and hierarchical component structuring. Based on this model, several extensions to VHDL are proposed, including nondeterministic assignments and unbounded asynchrony. Nondeterminism allows the ...

Formal verification of VHDL using VHDL-like ACL2 models

When a design reaches the register transfer level, essential architectural decisions have been taken; their validation required extensive simulation of the abstract behavioral specifications. The recognized need for formal verification cannot be met by current automatic equivalence and model checking tools, which mainly apply to logic synthesis inputs and outputs, or require manual abstraction....

Design of a Scalable Architecture of a Multimedia-on-demand Server

مداخل يعسوت رامعم ميمصت " ةجاحلا بسح ةددعتم طئاسو " ABSTRACT in this paper we develop a Vhdlbased scalable architecture of a multimedia on demand server model. Te three server subsystems are:the control subsystem, the communication subsystem and the storage subsystem are modeled. The communication subsystem is designed as an interconnection network with meshed-pipe structure and delivers packe...

Standard Verilog-VHDL Interoperability

During the last few years HDLs have become the driver behind the move to top down design in the electronic design industry. Two HDLs, VHDL and Verilog HDL have become the dominant de facto industry standard HDLs. Since the industry has made a hugh investment in both HDLs and there is every indication that each will retain significant market share for the foreseeable future, it is critical that ...
