  • Verilog_HDL的基本语法详解(夏宇闻版)

            Verilog_HDL的基本语法详解(夏宇闻版):Verilog HDL是一种用于数字逻辑电路设计的语言。用Verilog HDL描述的电路设计就是该电路的Verilog HDL模型。Verilog HDL既是一种行为描述的语言也是一种结构描述的语言。这也就是说,既可以用电路的功能描述也可以用元器件和它们之间的连接来建立所设计电路的Verilog HDL模型。Verilog模型可以是实际电路的不同级别的抽象。这些抽象的级别和它们对应的模型类型共有以下五种:   系统级(system):用高级语言结构实现设计模块的外部性能的模型。   算法级(algorithm):用高级语言结构实现设计算法的模型。   RTL级(Register TRANSFER Level):描述数据在寄存器之间流动和如何处理这些数据的模型。   门级(gate-level):描述逻辑门以及逻辑门之间的连接的模型。   开关级(switch-level):描述器件中三极管和储存节点以及它们之间连接的模型。   一个复杂电路系统的完整Verilog HDL模型是由若干个Verilog HDL模块构成的,每一个模块又可以由若干个子模块构成。其中有些模块需要综合成具体电路,而有些模块只是与用户所设计的模块交互的现存电路或激励信号源。利用Verilog HDL语言结构所提供的这种功能就可以构造一个模块间的清晰层次结构来描述极其复杂的大型设计,并对所作设计的逻辑电路进行严格的验证。   Verilog HDL行为描述语言作为一种结构化和过程性的语言,其语法结构非常适合于算法级和RTL级的模型设计。这种行为描述语言具有以下功能:   · 可描述顺序执行或并行执行的程序结构。   · 用延迟表达式或事件表达式来明确地控制过程的启动时间。   · 通过命名的事件来触发其它过程里的激活行为或停止行为。   · 提供了条件、if-else、case、循环程序结构。   · 提供了可带参数且非零延续时间的任务(task)程序结构。   · 提供了可定义新的操作符的函数结构(function)。   · 提供了用于建立表达式的算术运算符、逻辑运算符、位运算符。   · Verilog HDL语言作为一种结构化的语言也非常适合于门级和开关级的模型设计。因其结构化的特点又使它具有以下功能:   - 提供了完整的一套组合型原语(primitive);   - 提供了双向通路和电阻器件的原语;   - 可建立MOS器件的电荷分享和电荷衰减动态模型。   Verilog HDL的构造性语句可以精确地建立信号的模型。这是因为在Verilog HDL中,提供了延迟和输出强度的原语来建立精确程度很高的信号模型。信号值可以有不同的的强度,可以通过设定宽范围的模糊值来降低不确定条件的影响。   Verilog HDL作为一种高级的硬件描述编程语言,有着类似C语言的风格。其中有许多语句如:if语句、case语句等和C语言中的对应语句十分相似。如果读者已经掌握C语言编程的基础,那么学习Verilog HDL并不困难,我们只要对Verilog HDL某些语句的特殊方面着重理解,并加强上机练习就能很好地掌握它,利用它的强大功能来设计复杂的数字逻辑电路。下面我们将对Verilog HDL中的基本语法逐一加以介绍。

  • XAPP1065 - 利用Spartan-6 FPGA设计扩频时钟发生器

      Consumer display applications commonly use high-speed LVDS interfaces to TRANSFER videodata. Spread-spectrum clocking can be used to address electromagnetic compatibility (EMC)issues within these consumer devices. This application note uses Spartan®-6 FPGAs togenerate spread-spectrum clocks using the DCM_CLKGEN primitive.

  • XAPP708 -133MHz PCI-X到128MB DDR小型DIMM存储器桥

      The Virtex-4 features, such as the programmable IDELAY and built-in FIFO support, simplifythe bridging of a high-speed, PCI-X core to large amounts of DDR-SDRAM memory. Onechallenge is meeting the PCI-X target initial latency specification. PCI-X Protocol Addendum tothe PCI Local Bus Specification Revision 2.0a ([Ref 6]) dictates that when a target signals adata TRANSFER, "the target must do so within 16 clocks of the assertion of FRAME#." PCItermination transactions, such as Split Response/Complete, are commonly used to meet thelatency specifications. This method adds complexity to the design, as well as additional systemlatency. Another solution is to increase the ratio of the memory frequency to the PCI-X busfrequency. However, this solution increases the required power and clock resource usage.

  • CBC下写的串口编程

    CBC下写的串口编程,API函数实例 I wish this site had been around when I was trying to figure out how to make serial communications work in Windows95. I, like many programmers, was hit with the double-whammy of having to learn Windows programming and Win95 serial comm programming at the same time. I found both tasks confusing at best. It was particularly frustrating because I had, over the years, written so much stuff (including lots of serial comm software) for the DOS environment and numerous embedded applications. Interrupt driven serial comm, DMA TRANSFER serial comm, TSR serial comm, C, assembler, various processors... you name it, it had written it. Yet, everything I knew seemed upside-down in the message-driven-callback world of Windows.
