jpeyron Posted December 18, 2018 Share Posted December 18, 2018 Hi @gummadi Teja, Here is a Nexys 4 DDR Verilog keyboard project that should be easy to alter for the Nexys 4. You will need to use nexys 4 ddr's xdc as a reference for the nexys 4's xdc. thank you, Jon Link to comment Share on other sites More sharing options...
