WebHello, I have an FPGA design that uses 2 outside clocks (INCLK and TXCLK) from an ADC to latch data also coming from an ADC (TXOUT) and a system clock. A defined INCLK TXCLK and clk_sys as primary clocks in the timing constraints editor. When i run the timing analysis, it appears that i have old time violation. 1) there a hold time violation for … WebJul 2, 2024 · 好像不是我不喜欢的意思

Using ALTPLL and ALTCLKCTRL (Clock Muxing) - Intel Communities

WebFeb 6, 2024 · 02-06-2024 10:03 AM. Warning (15062): PLL in Source Synchronous mode with compensated output clock set to clk [0] is not fully compensated because it does not feed an I/O input register. Warning (15055): PLL input clock inclk [0] is not fully compensated and may have reduced jitter performance because it is fed by a non-dedicated input. WebMay 27, 2014 · All you need is 1. External oscillator (typically 50mhz) 2. One or more PLLs (ALTPLL megafunction) Get rid of clock_amp In your SDC file (which is simple and correct for this case) your created clock should match both the pin name and the period (in nanoseconds) of your external oscillator. Quartus can work out fine the ratios of its own … the phire group

Can LVDS clock pin be assigned to general differential IO?

WebMay 8, 2024 · Device: Max10 (10M16SAE144I7G) I am trying to use the ALTPLL IP core in my design for frequency synthesis. The clock input of the ALTPLL is directly fed by external oscillator via one of the dedicated clock input pin (have tried multiple pins incl. pin # 26, 27, 88, 89), but each time it gives the f... WebMar 18, 2024 · Employee. 03-23-2024 06:19 AM. 246 Views. Looks like Pin V9 and V10 is dedicated clk input , whereas W5 and W6 is not . PLL inclk should be from the dedicated clk pin. You can try to use the altclkbuf cntrl ip option. This might help to connect the non-dedicated input clk pin to clk tree in the FPGA.
