OR4E6-FPGA-EV

OR4E6 Evaluation Board Tutorial Overview This tutorial will assist first-time users of the ORCA OR4E FPGA how to use the evaluation board to understand the device features as well as the capabilities of the evaluation board. To use the tutorial, the user must have an installed copy of ORCA Foundry 2001 software and an understanding of the ORCA Device Programming Download Cable which is described in the Lattice Semiconductor technical note TN1009. Users should also reference the OR4E-680PBGAM Evaluation Board Users Manual. The tutorial and the supporting design files can be downloaded from the design tools section of the Lattice web site at http://www.latticesemi.com. The tutorial design was created for use as a template for future designs. This simple design will illustrate the functionality of the evaluation board Getting Started The following steps will make the proper board interconnections for power supplies, input signals, and output signals. • Add push-on jumper shunts for the following.
