New Contributorfitter error in Quartus Prime Pro 25.1.0.
Hello,
I am having trouble with a fitter error in Quartus Prime Pro 25.1.
set_global_assignment -name DEVICE 10CX105YF672I5G
I purchased a board with a 10CX105YF672I5G mounted on it, and am creating an FPGA design.
The tool I am using is Quartus Prime Pro 25.1.0.
I am assigning a user pin to Pin_AE5 in the design I am creating, but the fitter is displaying the following error message:
"Pin ~ALTERA_DATA0~ is assigned to pin location Pin_AE5 (IOPAD_X38_Y17_N61)"
However, Pin ~ALTERA_DATA0~ for this device should be Pin_Y4.
I think the pin information the fitter is using is incorrect. Please let me know if there is a solution.
Regards, Hidetaka

You're confusing AS_DATA0 (for active serial configuration) and DATA0 used as part of the 32-bit bus for the FPP configuration scheme. Check what configuration scheme you have selected in the Device and Pin options (Assigments menu -> Device).
You don't mention if this is a commercially available dev kit (if so, which one?) or your own design. Details on configuration schemes are here: https://www.intel.com/content/www/us/en/docs/programmable/683775/current/configuration-design-security-and-remote-29047.html
HidetakaHello, sstrell-san.
I don't think you've correctly understood my inquiry.
I'm assigning a signal to Pin_AE5. I'm getting a message saying that the Quartus Fitter cannot assign that pin to "~ALTERA_DATA0~". However, "~ALTERA_DATA0~" for this device should be Pin_Y4. The fitter pin is clearly wrong. There is an error in the device data used by the fitter.I think the problem is on the Quartus fitter side.
Incidentally, the configuration scheme is AS mode.Regards, Hidetaka,

Understood. Some configuration pins can be used as I/O after configuration and for some reason the tool is not seeing that here even though AE5 is not even being used in that way. I was just saying that Y4 (that you mentioned originally) and AE5 are both "DATA0" but for different configuration schemes.
I guess I would try creating a brand new project first just to rule out any settings or database corruption. After that, yes, it could be a bug.

Hello, sstrell-san.
Your message gave me a hint.
When I looked at the Dual-Purpose Pins setting, I saw that Data[0] was in Dual-Purpose Pins.This is my first time using the Cyclone 10GX, and in the Flex10K and other Cyclone families that I have used up until now, AS_Data0 and Data[0] were assigned to the same pin, so I assumed they were the same.
When I set DATA[0] to "Use as regular I/O", I was able to compile without errors.By the way, this is the board we will be using this time.

This board was first released in March 2019, but it seems that the Enpirion power supply IC was discontinued and replaced with a new one, resulting in the current version.
Thanks, hidetaka.
- sstrellAwesome! I forgot about the dual purpose pins setting.
