Error fitter for PHY IP gen3

[Moti]

Hi All,

I use Stratix10, quartus pro 20.3, I want to generate IP PHY of PCIe, gen3 configuration.(Single lane)

the fitter reports the following error: 

Error (15653): The Fitter cannot find a legal configuration for the following atoms. Update any outdated transceiver PHY IP cores, correct any illegal pin assignments, and then recompile your design.

 the design have 4 IP :

1. ATX PLL - PCIe Gen3 single lane 100MHz , PLL output frequency is 2500MHz.

2. fPLL - PCIe Gen1 and Gen2 single lane 100MHz, with enable to PCIe output port for hclk of the PHY. 

3. Native PHY - PCIe PIPE Gen3x1 Native

4. Transceiver PHY Reset Controller

there are no error or warning at any IP wizard.

I will thank you for your help, can not find the problem

Thanks,

Hi,

From the fitter error message, looks like it's complaining you are either using outdated Intel FPGA IP core or there is some invalid setting issue that caused fitter error later.

Typically Quartus fitter compilation error is either caused by wrong IP setting, wrong Quartus project top level design connection or wrong FPGA pin placement and pin setting issue.

Pls remove all sensitive FPGA core user design logic and just maintain the simplify design that just contains top level design with 4 Intel FPGA IP core that able to duplicate the fitter error.

Share your Quartus archived project *.qar then I can help to review your design to debug fitter error

Thanks.

Hi dlim,

thanks for your replay,  I remove all the project and compile only the 4 IP

I add the .qar file  ( please look for v2 )

( I want to mention that I succeed to compile PHY IP with gen1 AND gen2 with the same pins and constraints )

Thank you!

Attached is the fitter error fixed design for your reference

HI,

You are right. Your FPGA pin assignment setting is fine.

The problem is on your top level design connection. Below is the fix I made to your vqm design

1. Fixed broken NativePHY (tx_serial_data) connection

• I presume you want to connect to output port "DIFF100_PCIE_MOLEX_1KU12_PET" so I connect it back

1. Fixed wrong clocking connection to NativePHY for PIPE GEN 3

• fPLL tx_serial_clk should be connected to NativepHY tx_serial_clk0
  • ATX PLL tx_serial_clk should be connected to NativepHY tx_serial_clk1

You can also generate the example design directly from NativePHY IP to learn about the design connection

• Goto NativePHY -> design example tab
  • change the fPLL default frequency from 125MHz back to 100MHz
  • Then click generate example design button

Thanks.
