WebMay 2, 2024 · Wire, reg, wand (and almost all previous Verilog data types) are 4-state data objects. Bit, byte, shortint, int, longint are the new SystemVerilog 2-state data objects. There are still the two main groups of data objects: nets and variables. All the Verilog data types (now data objects) that we are familiar with, since they are 4-state, should ... WebBecause it is a net, the value of a wire can only be changed as the result of a gate or a behavioral statement driving it. A reg is a kind of variable. The value of a reg or register can be changed directly by an assign-ment. One should not confuse the Verilog reg with the hardware register. The reg is simply an entity that can hold a value. how to change units in chemcad https://victorrussellcosmetics.com
