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
