Error: Can't assign node "<name_pll>" to any location (ID: 176359)

Has anybody came across this error? After hours of searching, I can't find anything on this. 

 

I only get this error when I try to drive 8 or more register from one of the ALTPLL output. 

 

Error: Can't assign node "name_altpll:auto_generated|wire_pll1_clk[0]" to any location (ID: 176359)

Hi, 

 

Can post some part of your code? 

I have tried to drive 8 registers and it was without any error.

My apologies, I meant 14 registers or more. I'm trying to drive 14 register with clk27M. Here is a snippet of the code with 4 registers; there are 14 registers using this clk in total. 

 

 

PLL PLL(.inclk(clk50M), .c0(clkA), .c1(clkB), .c2(clkC), .c3(clkD), .locked(pll_lock)); 

 

reg [7:0] a = '0; 

always @ (posedge clkA) 

a = (some conditional statement) ? a + 1 : 0; 

 

reg[31:0][7:0] b = '0; 

always @ (posedge clkA)  

b[a[7:0]] = (some conditional statement) ? data : b[a[7:0]]; 

 

Thank you

My apologies, I meant 14 or more registers. I'm trying to drive 14 registers from the output of the ALTPLL with 27M and input of 50M.

Hi, 

 

Which device you are using? 

We can drive 14 or more registers, which depends on Number of LE available on device (FPGA) 

Do check the code again. 

i have tried to reproduce the error but it was successful compilation Check the image.

I'm currently using the MAX10; the model I used have one PLL. Please see attachment. 

If I comment out any one of the 14 reg I created and compile, I have a successful compilation. It only gives me an error when I leave all 14 reg in.

Hello, 

 

I didn't modify the .qsf file manually so I don't think this applies to my current error.
