Added PRBS test capability to DAQ optical path.
Switch to ISE 14.7; Removed SEM related modules from JTAG_access and put them in a separate module.
Version 3.68.  Implemented Soft Error Mitigation (SEM) IP Core.
Interfaced SEM controller to JTAG and CSP for control.
Counts single bit errors and double bit errors and reports when
double bit errors are detected and provides the frame address
where the error occured so that frame can be re-written.
(Also prepared JTAG user_wr_reg for auto-loading constants).
Version 3.69:
Removed SEM monitor out FIFO and replaced it with a 9 character pipeline.
Now use the monitor output to signal single and double bit errors.
Also use the monitor output as the source of the FAR address.
Version 3.6a: Fixed ASCII to hex conversion
Version 3.9a: Code for auto-loading constants from PROM with debugging code
Version 3.9c: Autoload constants with debugging removed
Version 3.a0: Debugging SEM FAR addresses
Version 3.a5: Added Startup Status register and QPLL Lock Lost counter.
Version 3.a5: Updated README and history files;
Branch ISE 14.6-trial is now merged into branch Pro.
