- 7 years ago
Hi Nanjunda,
I tried to replicate scenario & I observed the below results,please try to implement same at your end & if you have any different issue,let me know,
please find the below link & attachments,

Can you post the compile log , the actual error message as well as the Pin assignments you've used. It's not easy debugging without this information.
Hi Abe,
FYI the project is attached. You can compile it and check.
The errors are as below:
""Warning (15714): Some pins have incomplete I/O assignments. Refer to the I/O Assignment Warnings report for details
Warning (176674): Following 2 pins are differential I/O pins but do not have their complement pins. Hence, the Fitter automatically created the complement pins.
Warning (176118): Pin "MX_REFCLK_100MP" is a differential I/O pin but does not have its complement pin. Hence, fitter automatically created the complement pin "MX_REFCLK_100MP(n)"
Warning (176118): Pin "CE2_MX_CLKP" is a differential I/O pin but does not have its complement pin. Hence, fitter automatically created the complement pin "CE2_MX_CLKP(n)"
Error (169236): Can't place I/O pin Extr1 in assigned location IOBANK_2 made by User Location Constraints source
Error (169027): Pin Extr1 is incompatible with I/O bank 2. Pin uses I/O standard 3.0-V LVCMOS, which has a VCCIO requirement incompatible with that bank's VCCIO setting or other pins that use I/O standard LVDS.
Info (171121): Fitter preparation operations ending: elapsed time is 00:00:00
Error (171000): Can't fit design in device
Warning (169177): 1 pins must meet Intel FPGA requirements for 3.3-, 3.0-, and 2.5-V interfaces. For more information, refer to AN 447: Interfacing MAX 10 Devices with 3.3/3.0/2.5-V LVTTL/LVCMOS I/O Systems.
Info (169178): Pin MXFPGA_RESETIN uses I/O standard 3.3-V LVCMOS at 27
Warning (169069): Following 1 pins have nothing, GND, or VCC driving datain port -- changes to this connectivity may change fitting results
Info (169070): Pin Extr1 has GND driving its datain port
Error: Quartus Prime I/O Assignment Analysis was unsuccessful. 3 errors, 9 warnings
Error: Peak virtual memory: 5003 megabytes
Error: Processing ended: Tue Mar 05 13:36:59 2019
Error: Elapsed time: 00:00:02
Error: Total CPU time (on all processors): 00:00:02"
Thanks & Regards,
