Let me first talk about a problem I encountered:

There is a large schematic diagram with an FPGA chip connected to a CF card to store data.

There is a small schematic diagram, in which two analog signals enter an ADC chip (the chip has four ADCs and one 14-bit parallel output port), the ADC output goes to the DSP chip, and then into the CF card.

Now I want to add the small schematic to the big one, and the parallel output of the ADC goes directly to the FPGA, and then also to the CF card of the big schematic.

The problem is that I have never come into contact with FPGA. In order to complete this task in a short time, can I compare FPGA with microcontroller and find corresponding information?

For example, I don't know how to program embedded systems, but I can design circuits based on the default pin functions in the microcontroller data sheet. Does FPGA have this? For example, some pins can be used as parallel ports by default, while some pins are used for serial communication by default?

Also, why is there no pinout for Intel's FPGA, but a uniform electrical signature? Model: 10M40DCF484I7G

All FPGAs do not have similar pin configurations, because except for the analog-specific IO points, you can implement any function you want.

It seems that the poster has never been exposed to FPGA and doesn't know the basic concepts. Find someone who knows how to work with you. This is at least not something you can afford at the moment.

"I don't know embedded programming, but I can design circuits based on the default pin functions in the microcontroller data sheet. Is there such a thing for FPGA?"

You should look at the FPGA hardware manual

The parallel output of ADC is not the same as connecting directly to FPGA and MCU.

In FPGA, to improve the signal's anti-interference, the connection between ADC and FPGA should be differential signal output

Yes, this is indeed not my responsibility. Our project manager simply picked the best from the worst and forced the installation on me. He thought the schematics were already there and it would be easy to add it in. . . . . . .

Moderator, do you have any recommended materials? No need to learn programming, just application.

The key is that I can't even find a manual. I searched Intel's official website every day, but all I found were electrical indicators, but no pin definitions.

The current FPGAs are not integrated with SOC, PCI or other systems. Recently, I was looking up information and felt that FPGAs can also directly call ready-made ones. So I think there are power pins, clock pins, and various special communication pins.

Unfortunately, there is no such information. If there is, programming will not exist. Even if you have never heard of FPGA, you should know it just by logical thinking.

Then don’t you think about it, why not?

Since you haven’t seen it, the first thing you should doubt is your own “belief”.

Moderator, I am starting from scratch now. What are the best materials to start with? All I found are about programming. The task I need to deal with is the third one on my list. I estimate that it will take another 4 months before I can really start. There is still some time. Does the moderator have any recommended materials for beginners?

Friends, do you have any study materials? I have no basic knowledge, is there any suitable study material?

The flexibility of FPGA is different from that of embedded systems. It is recommended to learn the basics.

Let’s start with the Verilog language.

Alas, published on 2023-5-8 16:33 Moderator, I am learning from scratch now. What materials are better to start with? All I found are programming. The matter I want to deal with is ranked first on the current matter...

Using FPGA is actually programming. If you really want to learn, the books you should read are about programming. You said before that you don't know how to program, so I'm afraid you still need to learn more basic programming methods first.
