Immediately after the name of the module being istantiated we can pass the parameter, that can change the value of the parameter. So if we had written fulladder #(8) , we would have been instantiating an 8 bit adder. Although, the test bench may not be very good place to do it in ...

a Verilog construct calleddefparamto set the new parameter values. The first method is the most commonly used way to pass new parameters in RTL designs. The second method is commonly used in testbench simulations to quickly update the design parameters without having to reinstantiate the module....

1. 引言 在利用Verilog写数字信号处理相关算法的过程中往往需要对数据进行量化以及截位。而在实际项目中,一种比较精确的处理方式就是先对截位后的数据进行四舍五入(round),如果在四舍五入的过程中由于进位导致数据溢出,那么我们一般会对信号做饱和(saturation)处理。所谓
