Verilog 23 base counter

Hello, counter is a very widely used sequential circuit, in addition to counting, frequency division, but also widely used in digital measurement, operation and control, from small digital meters, to large digital electronic computers, almost ubiquitous, is an indispensable part of any modern digital system.

Counters can be constructed using flip-flops and gates. However, in practice, it is mainly composed by using integrated counters. When using an integrated counter to construct an n-base counter, it is necessary to use the zero terminal or the set number control terminal to make the circuit skip certain states to obtain the n-base counter.

A register is a circuit used to store binary data or **, which is a basic timing circuit. Any modern digital system must store the data that needs to be processed and store it so that it can be accessed at any time.

Registers are divided into two categories: basic registers and shift registers. The data of the basic registers can only be input in parallel and output in parallel. The data in the shift register can be shifted to the right or left in turn under the action of the shift pulse, and the data can be parallel input, parallel output, serial input, serial output, parallel input, serial output, serial input, parallel output.

Due to length limitations, the key part of the loss:

always@(posedge clk) beginif(~rst_n|(cnt==12)) cnt_r <= 4'h1;

else cnt_r <= cnt_r + 1'b1;

endassign cnt = cnt_r;

Brother Feng Lei is right.,There's no ASCII code in verilog at all.,There's no string.,Only 01.,And only 01 is the essence of the circuit.,The essence of the world.。。。 ab is the machine code 10101011, which has nothing to do with 16'h5758, and 16'h5758 is converted to machine code is 0101011101011000 If you have to make the two equal, you can only define a parameter of the name ab, the width is 16 bits, and the following statement is assigned parameter ab = 16'h5758; So you have what you call a string equal to 16'h5758.

I am an IC engineer, and I also use this for debugging, and many black core models can only use this to see the results. Some people will definitely ask, why don't you use a soft-core processor, use your sister, how much do you know about soft-core errors? Only the logical serial port can be used to judge the print result of the corresponding trigger event and compare the file.

If you're learning verilog just to prepare for exams, then I don't have anything to say.

But if you want to work as an IC design engineer in the future, I advise you not to study something like "strings are equivalent to values". Because for engineers, there is never a concept of "string" in **, only the data problem of various base representations.

Brother, have you solved this problem? Ask for advice.
