ISS has just release a new version of its free Wave VCD viewer 
(http://www.iss-us.com/wavevcd/). This viewer functions quite properly 
but is only conformant with IEEE VCD std. To generate such VCD files, it 
is necessary to modifie:
_Signal.py
_traceSignals.py

Enclosed are a modified version of these files. Testing is in progress 
and these files are given as it.

vcd-test.py is a modified version of the examle given in the tutorial 
and tb_fsm.vcd is the generated VCD file.

Warning: enum type has not been modified. Then states are denoted by 
integers ans no more by strings.

Hope this helps.
