Occasional ContributorStratix 10 Calibration Native Phy and Atx Pll
Hello. I have read document xcvr h/l tile stratix 10, and tested my project in ModelSim
I have 4 channels native phy with multiple profiles saved and embedded reconfiguration streamer
2 Atx pll with multiple profiles and embedded reconfiguration streamer
Timing for reconfiguration and calibration in simulation takes 3000-4000 clocks at 125 MHz.
But in hardware it takes 20-25 000 000 clocks at 125 MHz, the most time it take in atx pll calibration and tx/rx native phy calibration...
Can I not to use calibration in hardware, or what timing required for calibration. User_clk_1 have stable and free running clock from external oscillator.

Hi,
Q1. Can I use fpll as MCGB and dynamic reconfiguration it with profiles?
Ans - Yes.
Q2. Can I use fpll with mcgb and dynamic reconfiguration and atx pll with mcgb without dynamic reconfiguration. They goes to native phy serial clk 0 and 1. And I can mux them in native phy via reconfiguration interface.
Ans - It should be, please looked into the IP, If there are profiles in the dynamic reconfiguration tab, then profiles are supported.
Q3. Can i use fpll in Transceiver mode for 7GHz?
Ans - Maximum frequency for fPLL is 12.5Gbps (6250MHz).
Thank you
