Neil,
VCD specification is part of Verilog IEEE Standard itself. I
remember that some old version of the LRM was available with VCS
installations (look for ovi*.ps under VCS installation tree - if you
have VCS of-course).
About waveform viewer, I use GTKWave and am quite happy with it.
HTH,
Ajeetha
