6. Pin Assignments: Making them Spot On!

69K Students Enrolled
Course 1 of 4 in the FPGA Design for Embedded Systems Specialization
This course can also be taken for academic credit as ECEA 5360, part of CU Boulder’s Master of Science in Electrical Engineering degree. Programmable Logic has become more and more common as a core technology used to build electronic systems. By integrating soft-core or hardcore processors, these devices have become complete systems on a chip, steadily displacing general purpose processors and ASICs. In particular, high performance systems are now almost always implemented with FPGAs. This course will give you the foundation for FPGA design in Embedded Systems along with practical design skills. You will learn what an FPGA is and how this technology was developed, how to select the best FPGA architecture for a given application, how to use state of the art software tools for FPGA development, and solve critical digital design problems using FPGAs. You use FPGA development tools to complete several example designs, including a custom processor. If you are thinking of a career in Electronics Design or an engineer looking at a career change, this is a great course to enhance your career opportunities. Hardware Requirements: You must have access to computer resources to run the development tools, a PC running either Windows 7, 8, or 10 or a recent Linux OS which must be RHEL 6.5 or CentOS Linux 6.5 or later. Either Linux OS could be run as a virtual machine under Windows 8 or 10. The tools do not run on Apple Mac computers. Whatever the OS, the computer must have at least 8 GB of RAM. Most new laptops will have this, or it may be possible to upgrade the memory.

This course is very basic level and I encourage all the electronics students must take this course. Thank you Timothy Scherr Sir, he explained all the concepts with detailed explanation.
Nov 9, 2020
This is a very nice course that broadened my knowladge. I will be happy to continue next courses. Each video has need to be watched several times, there are a lot of useful information.
From the lesson
Programmable logic design using schematic entry design tools
In module 4 you will extend and enhance your design from module 2, completing the design by adding IP blocks, implementing pin assignments and creating a programming file for the FPGA. One outcome will be improved design productivity, by use of design techniques like pipelining, and by the use of system design tools like Qsys, the system design tool in Quartus Prime. You will complete a Qsys system design by creating a NIOS II softcore processor design, which quickly gives you the powerful ability to customize a processor to meet your specific needs.

Quartus II 64 bit assignment editor is causing strange error
I found this error not only from my circuit also various student's circuit.
Quartus just combine those names with ;. Is there any way that solve this error?
- \$\begingroup\$ Don't use names that differ only in the number at the end. Such names are treated by some tools as signals within a bus, and that appears to be what is happening here. Try using letters instead: a , b , c , etc. for inputs; x , y , etc. for outputs. Better still, use names that actually document the function of each signal. \$\endgroup\$ – Dave Tweed Nov 10, 2022 at 12:02

Pin Planner vs Assignments Editor
I just compiled a design using QUARTUS II version 13.0.1 and as expected PIN PLANNER automatically did choose pins for it. After that I opened the ASSIGNMENTS EDITOR and did not find any of the pins assignments made by the PIN PLANNER.
Is this the expected behavior? When a pin assignment should be made on the ASSIGNMENTS EDITOR vs the PIN PLANNER?
There's an option in the Pin Planner Edit menu to "Back Annotate" your fitter-assigned pins. This will write the actual assignment to your Quartus setting file (.qsf) and then it should show up in the Assignment editor (which really is a graphical parser for your qsf file). Good practice is to close the Planner as well to make sure it wrote in the assignments.
In general, I use the Pin Planner to pick pin locations, IO voltage and slew rates and the Assignment Editor for everything else.
Thanks a lot! The "Back Annotate" works exactly as you mentioned!
Normally I don't like the tool to automatically choose pins for me because it will probably cause a major headache to the layout guy. Just sayin....

Are you sure the pins are named PIN_ A21 and not just A21? I don't have Quartus installed anywhere so I can't check.
Full member level 2.
are you sure that you select the device correctly ? "assignment > device " if you've done anything correct in pin planner list of your inputs and outputs will be displayed and you can assign a pin for each from combo box

Reviewing Cyclone V manuals might help. A21 is a dedicated SoC resource, it can't be used as FPGA fabric I/O. For the same reason, the pin isn't offered in the Pin Planner selection when assigning I/O signals.

You didn't tell what you want to achieve, but apparently the development board design expects that the I2C is controlled by ARM processor.
Use assignment editor rather than pin planner, or check the .qsf file to see if there is another variable handling these pins. You are perhaps using as template a design not 'empty', so something is likely already assigned to those pins as they said above.

Hi, i wanted to connect a dac daughter board to de0 nano soc through LTC connector using i2c interface. after that need to send a 32 bit data(as specified in 2607 manual) to dac and read the voltage on output.i am using LTC 2607 as daughter board. thanks and regards Click to expand...

FvM said: I'm not sure if you understand the SoC FPGA concept. The Hard Processor System (HPS) has a number of dedicated I/O pins that can't be directly accessed by the programmable FPGA logic. A21 is one of it. It can be only used as I2C pin by the hardware I2C controller in the ARM processor and respective C code. The pin could be also configure as ARM GPIO, but that doesn't help for your intention to address the pin from FPGA logic. Click to expand...
if it not possible to access the pins, then how can i do it. Click to expand...
