用FPGA实现RS485通信接口芯片

在点对多点主从通信系统中,需要合适的接口形式和通信协议实现主站与各从站的信息交换。RS -485 接口是适合这种需求的一种标准接口形式。当选择主从多点同步通信方式时,工作过程与帧格式符合HDLC/SDLC协议。介绍了采用VHDL 语言在FPGA 上实现的以HDLC/ SDLC 协议控制为基础的RS - 485 通信接口芯片。实验表明,这种接口芯片操作简单、体积小、功耗低、可靠性高,极具实用价值。

US Navy VHDL Modelling Guide

This document was developed under the Standard Hardware and Reliability Program (SHARP) TechnologyIndependent Representation of Electronic Products (TIREP) project. It is intended for use by VHSIC HardwareDescription Language (VHDL) design engineers and is offered as guidance for the development of VHDL modelswhich are compliant with the VHDL Data Item Description (DID DI-EGDS-80811) and which can be providedto manufacturing engineering personnel for the development of production data and the subsequent productionof hardware. Most VHDL modeling performed to date has been concentrated at either the component level orat the conceptual system level. The assembly and sub-assembly levels have been largely disregarded. Under theSHARP TIREP project, an attempt has been made to help close this gap. The TIREP models are based upon lowcomplexity Standard Electronic Modules (SEM) of the format A configuration. Although these modules are quitesimple, it is felt that the lessons learned offer guidance which can readily be applied to a wide range of assemblytypes and complexities.

VHDL,Verilog,System verilog比较

本文简单讨论并总结了VHDL、Verilog，System verilog 这三中语言的各自特点和区别As the number of enhancements to variousHardware Description Languages (HDLs) hasincreased over the past year, so too has the complexityof determining which language is best fora particular design. Many designers and organizationsare contemplating whether they shouldswitch from one HDL to another.

基于CPLD的VHDL语言数字钟(含秒表)设计

利用一块芯片完成除时钟源、按键、扬声器和显示器（数码管）之外的所有数字电路功能。所有数字逻辑功能都在CPLD器件上用VHDL语言实现。这样设计具有体积小、设计周期短（设计过程中即可实现时序仿真）、调试方便、故障率低、修改升级容易等特点。本设计采用自顶向下、混合输入方式（原理图输入—顶层文件连接和VHDL语言输入—各模块程序设计）实现数字钟的设计、下载和调试。
