Bcd:binary Coded Decimal is a 4-bit binary encoding that represents a 1-bit decimal number.Definition: BCD code This encoding form uses four bits to store a decimal digit, making the conversion between binary and decimal fast. This coding technique is most commonly used in the design of accounting systems, because the accounting system often requires accurate calculations of long numbers of strings. Relative to the general floating-point notation, the use of BCD code, both to preserve the accura

Many new amplitude statements are added to system Verilog, although they are only applicable to blocking amplitude, but are useful in some situations.Here's an interesting piece of code that covers a few uses.1 Package definitions;2typedef enum LOGIC [2:0] {ADD,SUB,MULT,DIV,SL,SR} opcode_t;3 typedef enum LOGIC {UNSIGNED, signed} operand_type_t;4 typedef union PACKED {5Logic [ at:0] U_data;6Logicsigned[ at:0] S_data;7 } data_t;8 typedef struct PACKED {

Write Verilog many times, should know oneself write code circuit structure is what appearance, the following analysis:Module TB ( input CLK, input rst_n, input de, output [11:0] cntx), Reg [11:0] cntx; Always @ (Posedge CLK or Negedge rst_n) begin if (~rst_n) cntx The circuit structure was seen with synplify:Circuit diagram of the Verilog adder and D flip-flops implemented togeth

Recently learning Verilog HDL language, think learn in doing is a better way to learn, so we have to directly analyze and analyze the code well.First a wave of code: 1 Moduleq_decode_38 (data_in,data_out);2 3 input[2:0] data_in;//Port Declaration4 Output[7:0] Data_out; 5 Reg[7:0] Data_out;6 7 always@ (data_in)8 begin 9 Case(data_in)Ten 3'd0:data_out = 8'b0000_0001; One

Block symbol file--, suffix. BSF.Block design file--blocks the file, with the suffix. BdF.The BDF file is designed for the entire design, equivalent to a schematic diagram of the circuit, while the BSF file is implemented for one of the features in the design, equivalent to a component in the schematic diagram.By converting the Verilog HDL file into a BSF file and adding it to the BDF file, it facilitates the modular and visual design of the system.He

When you do chip verification, you will generally encounter the problem of slow simulation speed and low efficiency.A method is now found to debug the above problem. That is, using the NC Profiler tool.With regard to the profiler tool, I post the original document "Cadence®nc-verilog®simulator Help":The Pro?ler is a tool which measures where CPU time is spent during simulation. Although it is developed primarily to help Cadence R diagnose performance

The Verilog ' include and C's include usages are the same, and the difference may lie in that point.Include is usually a file, for Verilog This file is nothing more than a few parameter definitions, soHere are a few more keywords: ' ifdef ' define ' endif (they all bring a point, hehe).They unite to use, really can make your program diversification, take the Brother VGA program say things.First, you can cre

I can't wait to write these things myself. This chapter is essential for the development of hardware. Besides, we have to develop a CPU. ~ ~ often see someone released what Verilog code god Horse, feel very cow. In fact, you can also learn to. Manual up, follow along. In the previous chapters, we learned to design a variety of line diagrams, with levels of abstraction ranging from high to low, functional block level, logic gate level, MOS tube leve

friends, but also hope to get the high people of God's criticism!　　 　　 　　Preface　　[Machine Learning] The Coursera Note series was compiled with notes from the course I studied at the Coursera learning (Andrew ng teacher). The content covers linear regression, logistic regression, Softmax regression, SVM, neural networks, and CNN, among other things, and the main learning materials are from the machine lear

What is different between%s and%0s? (%s and% 0 s)%s prints the string as it is with spaces at the begining if string contentsis less than string variable size.Whereas%0s supress printing spaces.(If the contents of the string are smaller than the size of the string variable, the%s will be preceded by a space when the string is printed, and%0s will not add spaces (string head print))Here's an example. Hope this helps!Code:Module test (); reg [10*8:0] str = "Hello"; Initial begin $display

Half-integer divider: The counter is triggered by the rising edge, so when the count is N-1, the Count trigger is flipped, the clock's falling edge changes to the rising edge, so the count value is 0, so every time the n+0.5-frequency clock is generated, the trigger clock is flipped once. , using XOR gate and 2-way module design pulse deduction circuit, pulse deduction is the input frequency and 2 output difference or results.

can improve the portability and readability of the program.5) macro definition is to replace a string with a macro name, that is, to make a simple permutation, not a grammar check. Pre-processing is still the same, regardless of the meaning is correct. The error only occurs when compiling a source program that has been expanded by the macro.6) macro definition is not Verilog HDL statement, do not need to add semicolons at the end of the line.

Sometimes we need to put some classic things in the collection, always aftertaste, and Coursera on some of the courses are undoubtedly classic. Most of the end courses in Coursera provide a complete set of teaching resources, including PPT, video and subtitles, which will be very easy to learn when offline. Obviously, we will not go to a file to download a file, Only fools do so, programmers are smart! Wha

! I've been on this course 3 years ago, and it's been a long time ... Before going to bed to see this question, the day before yesterday wrote an article about learning Python in Coursera, just right question, so excerpt part, hope to be helpful:-) Let's talk about the process of learning Python in Coursera (and recommend this interesting professor, who wants to learn about Python).

friends leave a message saying they are already charged. Let's go to the official website and check it out! I have taken this course three years ago. It takes a long time ...... I saw this problem before I went to bed. I wrote an article about learning python in coursera the day before yesterday, which is just the right question. So I want to extract some of it and hope it will help me :-) Next, let's talk about how I learned python on

Write the first Verilog program yourself.Topic:Using a 10M clock, a single-cycle shape such as the following periodic waveform is designed.Thinking:The first idea is to define two counters to count and two enable flags to control the two variables separately. But this logic is too complicated, search on the internet, or the definition of a coun
