The purpose of this book is to present the Verilog language together with a wide variety of examples, so that the reader can gain a firm foundation in the design of the digital system using Verilog HDL. The Verilog projects include the design module, the test bench module, and the outputs...

Verilog HDL语言提供了编程语言接口,通过该接口可以在模拟、验证期间从设计外部访问设计,包括模拟的具体控制和运行。
finite state machine.) where the connections are N-bit wires. Use of an HDL language like Verilog allows expressing notations such as ASM charts and circuit diagrams in a computer language. Verilog provides both behavioral and structural language structures which allow expressing design objects at hi...
示例synth_design -control_set_opt_threshold 16 尽量避免使用异步置位/复位,因为它们只能连接到专用异步管脚,而无法通过综合迁移到数据路径。因此,综合控制集阈值选项不适用于异步置位/复位;(可以参考专栏内文章<【Xilinx-FPGA/VerilogHDL/Vivado】复位设计>) 在综合后,使用 opt_design -control_set_merge 或 opt...
Top-down design starts with creating a hierarchical design. This is a common design practice today, especially for large designs. However, the key is to make all circuit blocks in the hierarchy pin-to-pin compatible so that each can be represented by either a model or an actual transistor-...
三、Verilog HDL 1、过程语句: (1)initial:用于仿真模块中对激励向量的描述,或用于给寄存器赋初值,不带触发条件,其中的语句只执行一次,initial语句是面向模拟仿真的过程语句,是不可综合的; (2)always:其中的语句不断重复执行,always过程语句是可综合的;通常是带有触发条件的,触发条件写在敏感信号表达式中,当敏感信...
HDL的好处多多,最明显的一点是可以基于描述语言自动综合电路,绕过手工设计中的费力步骤(如卡诺图) 1.1 Design Methodology: An Introduction Design Flow(设计流程): Design specification设计规范 Design partition 设计分区(划分模块) Design entry: Verilog behavioral modeling 设计输入:Verilog行为建模 ...

You create the design hierarchy by instantiating modules in other modules. You instance a module when you use that module in another, higher-level module. Ports Ports allow communication between a module and its environment. All but the top-level modules in a hierarchy have ports. Ports can ...
