Jan,

  Ever since trying myHDL I've been using plain integers to define states
for all my code. In one of my modules where I tried using the enum, I
noticed that I got incorrect behavior (incorrect initial states, I
believe) if I didn't specify the encoding style. It worked correctly
when I specified 'encoding=3Done_cold'. I haven't tried other encoding
styles.

This was in the synthesized hardware (Xilinx ISE w/XST). I didn't
co-simulate this module. Is this dependence on encoding type something to
be expected when doing synthesis? I don't have the code ready to paste
(though I could possibly get something together) I'm just asking in
general.

Thanks,
George
