But you made me interested enough to go fire up the page in another machine/browser with Flash. Hmm ... spring-loaded animated charts ... in the 'Logic utilization' tab, there seems to be a mismatch between the full-scale outline at the bottom and the section viewed.
I tried AOL's webpage tester (http://www.webpagetest.org/result/100602_4TE/ ), to see how big was the Flash blob, but it timed out the first time.
A few other observations: you may want to add a line explaining how many (equivalent) k-gates are in the sample design, and how long it took to get the results (at the 1X speed ?).
Also, you may want to consider beefing up the 'How secure' answer in your FAQ. Guaranteed to come up.
VNC session for GTKwave ? I think I saw some mention of VNC-in-browser recently ...
Sign-up/sign-in worked OK. Thanks.
P.S. Forgive me, I'm sure you put a lot of work on those charts, but I would really suggest exporting reports to a boring Open Office spreadsheet that people could download, manipulate at will and print (or even view with Google Docs or similar, if they're in all-web-all-the-time mode).
