YMMV on that. I tried LogicView a couple years back. It punts on complex logic, which of course had to be the first 3 CALC blocks I threw at it. It also didn't have live updates for some of the paramenters (RIxx,...), so the "view" part wasn't all that helpful. And loading all the Qt libraries it depended on made startup pretty slow on my E box (but once it was in RAM, it ran OK). It may have improved since then, but we decided to pass at the time.

With this program you can view CALC/CALCA/MATCH/LOGIC block logic in a graphical way. It is even possible to extend the input/output labels with own information. This is a great piece of software that makes the CALC/LOGIC block function much easier to read and understand. It is installed so it can be called from the detail display.
