SPARTAN 3E TUTORIALS
Tutorial 6
Tutorial 6 shows how to create a design that utilizes the LCD display on the Spartan-3E starter board. Readers will learn how to adjust the timing of certain components in order to meet the requirements of the LCD display. For this tutorial the design will display "FPGA" on the LCD. The tutorial uses Xilinx ISE 10.1 and the Spartan-3E starter board.
This project was done with ISE 9.2 and ModelsimXE simulator
