This is a record of writing your own code
If the car overturns, ask a big guy to correct it
First, open quartus to create a new projectThen choose your own development board
During the epidemic, when I was at home and didn't have a board, I chose a kind of development board that was often used by my fri ...

Handshake Synchronization for Signal Transmission across Clock Domain
The so-called handshake means that both sides of the communication use special control signals to indicate the status. This control signal is different from the one-way contro ...

The author is receiving on-line training on FPGA, so as to come to the end, it is an entry point in terms of level. When designing, it is found that it is very important to make some design summaries, which can help us clear our thinking and get a good review for future review. I've been studying altera FPGA before, and I'm not familiar with xi ...

When I look back, I read two books and did a few minor projects. I watched some of the great gods chatting in QQ group. Sometimes I still put in a few sentences. It's normal that no one cares about a word. Sometimes they also help the netizens who are rookies to solve the problem. How embarrassing! In the words of the gods, they also draw a lit ...

Since learning FPGA, the only complete system that has ever been built is a multi-function digital table based on basys2. I remember that I had a lot of headaches when I did that. Finally, I used time to grind out a small system which was not very complete. At that time, I still had a full sens ...

When doing this experiment, I found a lot of information on the internet. It's all about using MCU to drive LCD display. It's really a lot easier to use MCU to drive LCD display. I remember when I asked questions in the learning and communication group of FPGA, I was instructed by my predecessors and ...

Firstly, the key and difficult points of asynchronous FIFO design are analyzed.
Finally, the detailed code is given.
I. A brief explanation of FIFO
The essence of FIFO is RAM, first in first out
Important parameter: fifo depth (in short, how many data needs to be stored)
fifo Bit Width (Bit Width per Data)
FIFO has two kinds: synchronous and ...

Complex interface design is realized by using state machine.
This is a converter that converts parallel data into serial output, using bi-directional bus output. This is derived from the reduction of EEPROM reader. Firstly, the characteristics of I2C bus are introduced.
I2C bus (inter integrated circuit) two-way two-wire serial bus protocol is: ...

There are many ways to describe a finite state machine in Verilog. The most common way to describe a finite state machine is to use always and case statements. The state transition diagram shown in the following figure represents a simple finite state machine:
Figure: The graph shows a four-state state machine with input A and Reset, synchrono ...

Time series analysis tools find and analyze all paths in the design. Each path has a start point and an end point. The starting point is the point at which the data is loaded by the clock in the design, while the ending point is the point at which the data is loaded by another time through the combinational logic.
The starting point in the pat ...
