它们就像函数的参数一样,在函数调用过程中被传递进来。 parameter MSB = 7; // MSB is a parameter with a constant value 7 parameter REAL = 4.5; // REAL holds a real number parameter FIFO_DEPTH = 256, MAX_WIDTH = 32; // Declares two
Parameters can be overridden with new values during module instantiation. The first part instantiates the module calleddesign_ipby the named0where new parameters are passed in within#( ). The second part uses a Verilog construct calleddefparamto set the new parameter values. The first method is ...
In Verilog, parameters can be overridden at the point of instantiation. This feature is particularly useful when instantiating multiple instances of the same module with different parameter values. By simply updating the parameter valuesduring module instantiation, designers can achieve great flexibility an...

Since you are using a "generic" interface, you must specify at the instantiation. (It might be possible to do "interface.Destinaion", but I'm not sure of that) So, now you have defined your modules that use the IParallel interface to be generic, so they will work w...
