Herb,

 I see.  Thanks for the clarification.  I haven't used that version
before, so I didn't know what it was.
 I assumed from the name that is was an online version.  But thinking
about it now, I should have known
 it wasn't an online version.  Oh well, live and learn. =20

 However, if it is basically the same as the ISE, then schematic capture
entry of the logic needed will
 be relatively easy.  It's basically a matter of placing logic symbols
and connecting them to achieve the
 function desired. =20

 Once one gains proficiency with CPLD's, working with FPGA's is more
easily understood.  And FPGA's can=20
 hold many times more complex functions than a CPLD.

 And if you work with Mixed Signal FPGA's, you can create your own Mixed
Signal ASIC type circuits and
 chipset(s).

 Regards,

 Jim
