FPGAXpose 1.5
---------------------------------------------------------

Welcome to FPGAXpose, a debug tool for Xilinx FPGAs.

Documentation including tutorials is available from the 
FPGAXpose Viewer's help menu and from the start menu.  It
is advisable to work through the tutorials before using
FPGAXpose on your own designs.

Release Notes 1.5
-------------------
- The Create new bus feature now works correctly.
- When reading Block Rams the first 32bits are now read correctly.
- Menu options relating to the FPGAXpose core have been removed.
- Fix for USB port number selection.

Known Issues
------------
- Not all BRAM primitives can be monitored correctly.  This issue
  has been seen with the RAMB18SDP primitives.  When the contents of
  RAMB18SDP primitives are readback the values will always be incorrect.
  This appears to be a mapping issue where the addresses of the monitored
  bits in FPGAXpose are incorrect and are jumbled up.  Data from standard
  RAMB18 and RAMB36 primitives can be readback correctly.

Prerequisites
-------------

ChipScope Pro 10.1i or 9.2i should be installed on the machine.


Platforms Supported
-------------------

FPGAXpose currently supports the following platform:

- Windows XP
- ChipScope Pro 10.1i or 9.2i.
- Virtex 5, Virtex 4, Spartan 3, Virtex 2, Virtex 2 Pro and 
  Virtex 2 Pro-X.
- Cables: Parallel 3, Parallel 4, MultiPro, Platform USB.


Installation
------------

The installer uncompresses the FPGAXpose files into the
chosen installation directory and optionally creates a Start menu
group and desktop icon.  It also sets up two environment 
variables:

- FX_CHIPSCOPE_HOME
- FPGAXPOSE_HOME

The installer also creates registry entries to record the 
installation directory location and the start menu location.

The installation does not modify any existing program 
installations.


Registration Information
------------------------

A registration code is required to activate the product. If you

Release Notes 1.4
-------------------
-Support for the FPGAXpose Core removed.
-Support for ChipScope 10.1 added.


Release Notes 1.3
-----------------
- The ncd2ll program can now be used to generate .ll files quickly for a
  large number of devices.  These generated .ll files also include the
  names of the BlockRam instances.  This allows the FPGAXpose Viewer
  to name the BlockRams accordingly.
- The device files associated with ncd2ll are now a seperate download.
- Ability to dimension BlockRams with different widths and depths and 
  view the associated parity bits beside the data bits.
- Ability to export the Trigger Immediate signal values to a csv file 
  suitable for opening in MS Excel.
- Ability to specify Big or Little Endian for signals.

Release Notes 1.2
-----------------
- A large database of known devices is now pre-installed.
- Updated documentation.
- Virtex 5 support.
- More user friendly error messages.
- FPGAXpose can now be used with mixed ISE and ChipScope service packs.
- The ncd2ll program is now included and reduces the time required to 
  generate logic allocation files.
