Introduction

NanoXplore provides a tool in order to compute:

  • NX_PLL parameters

  • NX_WFG parameters

  • constrainModule constraints

Examples

NX_PLL

$ make pll_calculator_interface
pll_calculator_interface
Please set the variant ?
 1 - NG-MEDIUM 
 2 - NG-LARGE 
 3 - NG-ULTRA

How the reference clock is generated ?
 1 - External 
 2 - Internal (internal oscillator)
1
What is the reference clock frequency in MHz ?
50
Do you want to set a VCO frequency or let the tool research automatically ?
 1 - Set VCO frequency 
 2 - Automatical research with 1st output clk
2
How many output clocks do you want to generate in the range [0;9] ?
2
What is the frequency of the output clock 0 in MHz ?
400
What is the frequency of the output clock 1 in MHz ?
200
