一、2x1 MUX实现逻辑门(传输门可化简) 各种逻辑门均可以使用三目运算符实现,三目运算符F = X?B:A 对应于2x1 MUX可见下图。 1、与门:F=A?B:0;或门:F=A?1:B;非门:F=A?0:1;传输门:F=A:1:0; 2、异或:F=A?(B?0:1):(B?1:0);同或:F=A?(B?1:0):(B?0:1);(传输门化简后仅使用2个2选1MUX),其中in

Our code is written in standard SystemVerilog (IEEE 1800-2012, to be precise), so the more important question is: Which subset of SystemVerilog does your EDA tool support?We aim to be compatible with a wide range of EDA tools. For this reason, we strive to use as simple language ...
My SystemVerilog code is heavily commented for ease of readability. Ultimate goal: Build a SystemVerilog system that reads Ethernet packets on one port and reflects them directly out another port, and vice versa, allowing the FPGA to be a bidirectional repeater. Do all these things without a ...
