例如,考虑用 VHDL 实现一个简单的 4 位计数器: library ieee; use ieee.std_logic_1164.all; use ieee.numeric_std.all; entity counter is port ( clk :instd_logic; reset :instd_logic; count : out unsigned(3 downto 0) ); end entity counter; architecture behavior of counter is signal count...

Otherwise, Verilog language was first language can support any mix design level , At the same ...
Teal : open source c++ class library for verification Utils FSMDesigner : FSMDesigner is a Java-based Finite State Machine (FSM) editor, which allows the hardware designer to specify complex control circuits in an easy and comfortable way. The graphical FSM is converted into a proprietary state...
系统Verilog断言(SystemVerilog Assertion,简称SVA)是一种在硬件设计中用于验证和调试的技术。它是一种基于属性的形式化验证方法,用于描述和检查设计中的行为和性质。 $rose是系统Verilog中的一个断言函数,用于检测信号在上升沿(从低电平到高电平的过渡)时的状态。它返回一个布尔值,如果信号在上升沿时为真,则返回1,...

(4)更完备的库(Library) 在电路设计的各个阶段,EDA系统需要不同层次、不同种类的元器件模型库的支持。EDA 工具要具有更强大的设计能力和更高的设计效率,必须配有丰富的库。各种模型库的功能和规模是衡量EDA工具优劣的一个标志 4.基于EDA技术的设计思路(P4~P5) (1)Top-down设计,即自顶向下的设计 将设计分成几...
1:进数字IC前端/FPGA设计的专业知识学习,sky推荐这本书:《CMOS VLSI Design A Circuits and Systems Perspective》。自认为是数字IC设计入门“圣经”。基本电路结构,加减法器结构,组合逻辑,时序逻辑,跨时钟设计都有涉及。 2:在此还需要理解On-Chip-Bus的基本知识与一个数字系统的基本结构,建议学习理解:AMBA总线,含...
