Introduction

NanoXplore provides a tool in order to compute:

  • NX_PLL parameters : Generate parameters to set when instantiate NX_PLL in VHDL code

  • NX_WFG parameters : Generate parameters to set when instantiate NX_PLL in VHDL code

  • confineModule constraints: Generate constraints to set to create and confine modules

 

Examples

NX_PLL
