WebNov 30, 2024 · 1 Answer Sorted by: 2 They are functionally the same in your example. There are slight differences when adding a delay to a wire declaration. wire #5 A = B & C; wire A; assign #5 A = B & C; In the first form, the delay gets added to all other net drivers. You can also use SDF back annotation to modify the wire delay. WebNov 16, 2024 · logicはassignでもalwaysでの代入でもどちらでも使える。 要するにwireとregの両対応版。 VHDLのsignalと同等。 Verilogではassignの時にはwire,alwaysの時にはregといちいち気にしなくてはいけなかったが、System Verilogではlogicにしておけば一切気にする必要ない。 なので今日からはlogicを使ってみよう。 今までVerilogしか使って …

WebThe only real difference between wire and reg declarations in Verilog is that a reg can be assigned to in a procedural block (a block beginning with always or initial ), and a wire can be assigned in a continuous assignment (an assign statement) or as an output of an instantiated submodule.

This is because the behavior of the logic type is generally more intuitive than the reg and wire types. Despite this, we still make use of continuous assignment in SystemVerilog as it provides a convenient way of modelling combinational logic circuits. ip65 ceiling light customizedWeb1.) logic is for driving asynchronous signal. 2.) wire (or net) is for driving synchronous signal. So if we combine them both, does that mean that a wire logic interface signal can be driven both asynchronously and synchronously? The reason why I'm asking this is because I can't drive the wire logic interface signal in my driver. ip65 fluorescent light fittingsWebApr 10, 2016 · In simulation, a Verilog wire behaves like a piece of metal, a track, a wire, whilst a Verilog reg is a variable, it is storage*.
