A. DESCRIPTION
--------------
The JBlaster is a software driver that allows you to configure Altera's PLDs 
through the ByteBlasterMV in JTAG mode. The programming input file supported 
is in Raw Binary File (.rbf) format. The JBlaster also requires a chain description 
file (.cdf) generated by the Quartus II software (Please refer to Note 1). 
The JBlaster is targeted for embedded JTAG configuration. The 
source code has been developed for Windows NT. You can customize the code to
make it run in other platforms (Please refer to the JBlaster white paper).

B. INCLUDED

E. NOTES
--------
Note 1		The Quartus II software generates a CDF that accepts input programming file that is
		in SOF format. The user needs to open up the CDF using Notepad, edit the source file
		name by changing it from *.sof to *.rbf (The user needs to generate an RBF). This is
		because the current version of the JBlaster supports RBF as the input programming file.
