Please help with PLL

[Altera_Forum]

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

Yes, it works fine, when I use just clk (it comes from V11, https://screencast.com/t/bdsshstrk ) 

Is it true that pll_reset is not necessary to start pll?
