While the previous examples work for vectors as well as arrays of any kind, using the shift_left function only works with bit vectors. The definition of the shift_left function and it’s complementary shift_right function appears in the ieee.numeric_std package. It requires an unsigned vector...
VHDL probably allows you to have two dimensional arrays in the component's ports.Verilog does not...
我正在VHDL上制作一个Viterbi解码器,几乎所有的东西都按计划工作,所有的arrays都被正确填充了。 唯一的问题是输出解码比特的最后一步不起作用,变量temp_dec似乎永远不会改变它的值(现在temp_dec和smallest_metric是信号,因为我试图找出它们被分配的值,但它们应该是变量)。
