Error 170084 ADC & PLL

Given:

Quartus 14.1.1 build190

BeMicro Max 10

10M08DAF484

System clock on N14

Error (170084): Can't route signal "ADC06:inst|ADC06_altpll_0:altpll_0|ADC06_altpll_0_altpll_5q22:sd1|wire_pll7_clk[0]" to atom "ADC06:inst|ADC06_ADC:adc|altera_modular_adc_control:control_internal|fiftyfivenm_adcblock_top_wrapper:adc_inst|fiftyfivenm_adcblock_primitive_wrapper:adcblock_instance|primitive_instance"

ADC.qip is the only file in the project and it consists of Qsys IP "Altera Modular ADC core, Avalon ALTPLL and JTAG to Avalon Master Bridge.

I am having trouble compiling a the project using system clock on N14. If I compile the project on Clock pin N9 then compilation will complete without errors.

What am I doing wrong?

Thank you in advance.

Mike

    I found that if I inserted another ALTPLL between the N14 clock pin and the Qsys ADC symbol the project will compile.

    Why are two ALTPLL's required?

    I think that a PLL can have only one clock input. You have two clocks, thus you need two PLLs? It might also work with two QSYS clk input blocks.

    The Qsys pictures below better describes the problem. If I attach the system clock pin to N14 I must add a second altpll (altpll_1) or the compiler will fail in fitter. If I attach the system clock pin to N9 then I can use a single altpll (altpll_0) and compile without errors.

    I am wondering why fitter cannot connect to N14 with a single altpll.

    I found it. Bummer!

    From the Max 10 ADC data sheet.

    "Depending on the device package, the MAX 10 devices support one or two PLLs—PLL1 only, or PLL1 and

    PLL3."

    The BeMicro Max 10 Sys Clk is on pin N14 or PLL2.

    And what about QSYS ADC tool, does it work with all of it? In my case - no. :cry:

    It turns out you can use the Assignments Editor to specify a location for a given instance of the PLL. On a new (blank) line, select "location" In the Category column. Use the Node Finder in the "To" column to find the instance. Then in the Value column, select the element type as PLL, which in my case gives two choices: PLL_1 and PLL_2. I found PLL_1 is the useful one.

    By the way, the very next sentence following "Depending on the device package, the MAX 10 devices support one or two PLLs—PLL1 only, or PLL1 and PLL3." is "For devices that support two PLLs, you can select which PLL to connect to the ADC." which seems to be incorrect.

    hi i have the same error-code

    coud you take a screenshot of the pinn-assignment ?

    I wasted too much time on this board. I ended up making my own Max10 prototype board with 25Mhz clock, JTAG, 8Mb SDRAM, (2)4ch opamps and .1" headers.

    We tend to look for all the bells and whistles when we first start out, but less is more. It can be very frustrating going back and forth through their schematics to find out which IO is not being used by their added peripherals. Several of these pins can be shared but you end up looking through all of the data sheets to find which ones.

    The Altera EK-10M08E144ES/P is a nice simple evaluation board. I would have purchased this board if it had SDRAM.

    Hi Kikell7, are you using E144 part on your own design?

    I am stuck at my design still refuse to work, I think I can buy EK10m08, but I am using SC part and Ek moount an SA.

    Pin variation across model on E144 series is another trouble, so seems like 5 series exists, 02, 08sa-25sa, 08sc-25sc, 40-50SA, 40-50SC.

    Regards
