Multiple pin error?

Seems like a dumb question, but its strange to me as I havent used this version of Quartice for a bit.

I have a Web Edition.

In trying to compile the EP3C55 I get 3 multiple pin error messages of the same kind.

Cant place multiple pins assigned to locations ..

The pin assignment and pin planer dont show any duplicates or unassigned pins. All the pins are

on the top level schematic correctly. Yet I get this message which I dont understand.

My help files on Quartice are non functional.

The final error is Can't fit design into device.

However before pin assignments it fit with a small percentage of chip used. I've added some to it since

but not much. I hope someone can give me some clues.

Thanks

    It could happen if some dual purpose pins aren't configured as regular I/O. But without the actual error message, I can't get my crystal ball to work to find out what you can do to fix the problem.

    I am using Cyclone IV EP4CE115F29C7 device, and getting below Error. Even I imported the DE2_115_pin_assignements.csv file came in altera CD.

    Could you please let me know why I am getting this error and how to resolve it.

    Which of those signals are actually used in your design, between HEX1, GPIO_1, KEY, HEX0, LEDG and LEDR? It's possible that the assignments you took from the CD mapped some extra ports that you don't use. You will need to go into the assignment editor and delete manually all the pin definitions for the signals you don't use.

    Hi ,

    I have removed all the additional pin assignments which were imported from DE2_pin_assignemnet file.But still getting ERROR.Please find the attached pin assignment doc and error file. Below is top level pins that I am using.

    module rs232lab(

    input CLOCK_50, // 50 MHz clock

    input [3:0] KEY, // Pushbutton[3:0]

    input [17:0] SW, // Toggle Switch[17:0]

    output [6:0] HEX0,HEX1,HEX2,HEX3,HEX4,HEX5,HEX6,HEX7, // Seven Segment Digits

    output [8:0] LEDG, // LED Green

    output [17:0] LEDR, // LED Red

    inout [35:0] GPIO // GPIO Connections

    // UART

    output UART_TXD, // UART Transmitter

    input UART_RXD, // UART Receiver

    // LCD Module 16X2

    output LCD_ON, // LCD Power ON/OFF

    output LCD_BLON, // LCD Back Light ON/OFF

    output LCD_RW, // LCD Read/Write Select, 0 = Write, 1 = Read

    output LCD_EN, // LCD Enable

    output LCD_RS, // LCD Command/Data Select, 0 = Command, 1 = Data

    inout [7:0] LCD_DATA // LCD Data bus 8 bits

    )

    // All inout port turn to tri-state

    assign GPIO = 36'hzzzzzzzzz;

    Thanks,

    I think the warning is self-explanatory. You have an inout port called GPIO with 36 bits, so you must assign pins to those 36 signals. The same with HEX2. If you go into the pin planner you should see a list of all unassigned signals and give assign them an FPGA pin.
