Verilog wire type

1.Nets（ Internet connection ）：

Wiring driven by modules or gates . The change of the driver signal will be immediately transmitted to the output line .

for example ： The figure below ,selb Changes , It will automatically and immediately affect the output of or gate .

Connect （Nets） Types of type variables ：

type                                         function                                         

wire,tri                       Corresponding to the standard interconnect （ default ）

supply1, supply2   Corresponding to power line or ground wire

wor, trior                   Corresponding to a line or logical connection with multiple drive sources

wand, triand           Corresponding to the line and logical connection with multiple driving sources

trireg                         There is a connection that can temporarily store the level corresponding to the capacitor

tri1, tri0                     Corresponding to the connection that needs to be pulled up or down

If you don't specify the type of connection , It should mean wire type . It defaults to 1 position wire type .

Specially designated wire type , It may be multiple or to make the program readable .
