VHDL库，仿真时使用的，包括打印，类型转换等实用的操作(Practical operation VHDL library, using simulation, including print, type conversion, etc.)

IC的设计可以分为两个部分，分别为：前端设计（也称逻辑设计）和后端设计（也称物理设计），这两个部分并没有统一严格的界限，凡涉及到与工艺有关的设计可称为后端设计。(The design of IC can be divided into two parts: front-end design (also called logic design) and back-end design (also known as physical design). These two parts do not have a uniform and strict boundary, and the design related to process can be called back-end design.)

设计一个十进制计数器模块，输入端口包括 reset、up_enable 和 clk，输出端口为 count 和 bcd，当 reset 有效时（低电平），bcd 和 count 输出清零，当 up_enable 有效时（高电 平），计数模块开始计数（clk 脉冲数），bcd 为计数输出，当计数为 9 时，count 输出一 个脉冲（一个 clk周期的高电平，时间上与“bcd=9”时对齐）(Design of a decimal counter module, input port, including the reset up_enable clk, output port for the count and bcd, when reset is active (low), the bcd and count output cleared up_enable active (high), count module starts counting the (the CLK pulse number), the BCD count output when the count 9, the count output of the high level, the time of a pulse (a clk cycle with " bcd = 9" when aligned))
