morse code

[a.h e.j]

hello every one
i want to wtite morse code in verilog in modelsim and just simulation
for rx and tx
how can i write it?
thanks

Not in Verilog but this might help a small bit:

I've used a subset of Morse code to reduce the number of
status LED's in one design. In that case I only needed to
transmit, and only characters 0-9 and A-F. However the
transmit is the easy part. Receiving Morse code requires
something like auto-baud detect, and if you don't want to
miss the beginning of a message you'll need storage for
the parts that came in before you determined the dot rate.
Machine-generated morse code would be easier to receive
than hand-generated morse.

If this is only for simulation, you might want to look for
C programs that do this. Perhaps the ARRL has something
like you want.
