-- Vhdl Source Files:
  i2c.vhd   -- top level file
  i2c_control.vhd  -- control function for the I2C master/slave
  shift.vhd  -- shift register
  uc_interface.vhd -- uC interface function for an 8-bit 68000-like uC
  upcnt4.vhd  -- 4-bit up counter
  i2c_timesim.vhd  -- post-route I2C simulation netlist
     
--VHDL Testbench Files:
  micro_test.vhd  -- top-level VHDL testbench for functional simulation that
        instantiates micro_tb.vhd, pullup.vhd, and i2c.vhd.

  micro_tb.vhd  -- VHDL functional simulation testbench that tests two
        instantiations of the I2C design. It configures
        one as a master and one as a slave and then
        the two I2C designs transfer data over I2C.
  micro_test_post.vhd -- top-level VHDL testbench for post-route simulation that
        instantiates micro_master_tb.vhd, micro_slave_tb.vhd,
        pullup.vhd and the post-route VHDL model time_sim.vho
  micro_master_tb.vhd
  micro_slave_tb.vhd -- These two files test the post-fit VHDL files output from
        Project Navigator. Since in the post-fit VHDL the uC
        address is hard-coded,  both instantiations of the I2C
        design have the same uC address. Therefore separate
        testbenches are needed to talk to the two instantiations
        of the I2C design; one that configures one of the I2C
        designs as a Master, one that configures the other I2C
        design as a Slave.
  pullup.vhd  -- models a pull-up resistor
  upcnt4_tb.vhd  -- functional testbench for upcnt4
  upcnt4_tb_post.vhd -- post-route testbench for upcnt4
-- ModelSim DO files:
  micro_test.do  -- functional simulation script file that calls wave.do
  wave.do   -- configures wave window for functional simulation
  micro_test_post.do -- post-route simulation script file that calls wave_post.do
  wave_post.do  -- configures wave window for post-route simulation
-- Report Files
  i2c.rpt   -- Project Navigator fitter report file
  i2c.cxt   -- XPower input data file

-- XST Files
  i2c.npl   -- Project Navigator project file
  i2c.jed   -- JEDEC programming file with I2C fit to a XCR3256XL-7-TQ144
