接下来补全HDL文件中”implementation missing“的部分 基本上,我们所做的是我们开始描述这张gate diagram, one chip part at a time 对于我们拥有的每一个芯片零件,我们都会写一个单一的 HDL 语句,描述芯片及其所有连接。 一些关于HDL的comment 注意,有一些书写HDL的习惯与写Python或者Java的习惯一样,变量的合理命名...
Gate Logic: A gate is a physical device that implements a Boolean function. The simplest gates of all are made from tiny switching devices, called transistors, wired in a certain topology designed to effect the overall gate functionality. Gate里的逻辑一般用diagram来表示。 思考题:Xor(a,b)的can...
Application of AND Gate AND gates can function as Enable gates orInhibit gate. Enable gates allow data through a channel, while Inhibit gates block it. For example, in frequency measurement, a known gating pulse enables the passage of the waveform to be measured. The diagram below shows this ...

In the previous chapter the inverter was described, which is the basic building block for making logic circuits. A schematic diagram of a NOR gate is shown in figure 5.1, with transistor T3 as the load transistor. If a high voltage is applied on input A,
Figure 2.5.7(b) shows a separate AND gate and inverter being used to produce the NAND logic function. Also notice that the Boolean expression for the AND gate, (A.B) and the NAND (A.B)??are shown on the logic diagram of Fig. 2.5.7(b). The truth-table for the NAND gate is ...

There can be more than two inputs to a logic gate. The output of a gate can be inverted (complemented) to provide a different logic function. If the output of the OR gate is inverted, it becomes a NOR gate. If the output of the AND gate is inverted, it becomes a NAND gate. The...
