/////////////////////////////////////////////////////////////////////////// // // Filename: ICAP_SPARTAN6.v // // Project: XuLA2 board // // Purpose: Verilator cannot build the ICAP_SPARTAN6 primitive for the // XuLA2 board. This file is provided for Verilator to build // instead. It is *not* a fully functional ICAP_SPARTAN6 primitive by // any stretch of the imagination, but it makes the build process work. // Reads and writes should "succeed", the values read or written however // will be meaningless. // // // Creator: Dan Gisselquist, Ph.D. // Gisselquist Technology, LLC // /////////////////////////////////////////////////////////////////////////// // // Copyright (C) 2015, Gisselquist Technology, LLC // // This program is free software (firmware): you can redistribute it and/or // modify it under the terms of the GNU General Public License as published // by the Free Software Foundation, either version 3 of the License, or (at // your option) any later version. // // This program is distributed in the hope that it will be useful, but WITHOUT // ANY WARRANTY; without even the implied warranty of MERCHANTIBILITY or // FITNESS FOR A PARTICULAR PURPOSE.
