8 years agoPlease help with PLL
Hello!
I'm trying to use PLL to increase frequency of my system. I use Quartus 17 and de0-nano-SoC board. Steps I did: 1. On my IP catalog I chose Altera PLL: https://screencast.com/t/nshqodhrq 2. Set settings as the following: https://screencast.com/t/vphamvpt (I have tried to set "Enable locked output port" and "Enable physical output clock parameters" doesn't help) 3. Once qip/sip is generated and added to the library on my top module I do :
module top_module (
input clk
);
reg clk_pll;
reg pll_reset = 0;
newpll testpll (.refclk(clk), .rst(pll_reset), .outclk_0(clk_pll));
....
But the system doesn't work, modules don't receive signals by clk_pll Please, any suggestions
