4 years agoError fitter for PHY IP gen3
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 ...

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
- 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
- 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.
