AXI-Lite interface updated, now tested and verified on Xilinx FPGA
renamed C_DEVICE parameter, because of conflicts with restricted parameter in xilinx XPS |

made rw_address a vector of a fixed width |

removed C_NR_OP and C_NR_M from the generic of mod_sim_exp_core and made them contstants, because currently no other values than 4 an 2 resp. are supported/can be implemented. |

big update, the mod_sim_exp core now has a selectable ram structure. a generic ram that should be usable in any fpga, a asymmetric ram that is usable for some devices of altera or xilinx and uses less resources. |

now using a generic description of the ram for the memory. the core now should synthesize for al fpga's, no device specific code anymore. tested and synthesizes for altera and xilinx |

changed files to remove warnings from synthesis
last cell logic is simplified because of redundant logic |

/mod_sim_exp/trunk/rtl/vhdl/core/mod_sim_exp_core.vhd |
| 37 |
changed names of some generics of the multiplier.
moved the parameters for the core to the package of the core
testbench now uses this parameters to adapt to different bit widths
and new systolic pipeline now supports split or single pipeline |

found bug in new pipeline structure, now working properly. (tested in sim)
mod_sim_exp_core uses new flexible pipeline as default. |

operand memory now supports custom operand widths, the internal memory stays the fixed 1536 bit, but the bus width is now adjustable to any size below. |

default pipeline changed to old version, there seems to be an occasional error with new version. |

new systolic pipeline structure now has split pipeline support, tested and verified in simulation. the core now uses this pipeline by default. |

updated vhdl sources with new header according to OC design rules and formated code
added makefile and simulation input file for testbench simulation |

First version of VHDL source(working), still contains xilinx primitives and needs to be updated to the OpenCores design rules.. |
