added README file for simulation, minor update for Makefile clean target. |

changes in makefile, and fifo's are now also in mod_sim_exp library |

new control logic for the core, allow for greater frequencies for the multiplier.
changes:
- autorun_cntrl: the bit selection for the exponents is now implemented with a shift register in stead of a mux. credits to Geoffrey Ottoy for new design structure.
- mont_cntrl: gave the databus from and to the RAM more time to settle. data now has 3 clocks to get to its destination. |

BIG update: core now supports different clock speed for the multiplier core, so more performance is posible. currently this version is working in simulation and is being tested on hardware. Changes in this update include:
- changed RAM and memory to support different clocks
- new FIFO that supports dual clock (slightly modified version of generic_fifo's on OpenCores.org)
- parameter C_FIFO_DEPTH is now replace by C_FIFO_AW (address width of the fifo pointers)
- added logic for control signals to cross from one clock domain to another
- updated testbenches and interfaces accordingly
- added log of synthesis of the 2 new fifo's for Xilinx |

updated documentation with minor interrupt changes of AXI interface |
JonasDC |

/mod_sim_exp/trunk/ |

changed interrupt structure of AXI4-Lite interface. Now the interrupt has to be acknowledged by clearing the appropriate interrupt source flag in the control register. |

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. |
