I'd been struggling to meet timing constraints in the S3 when I realized that I should have been using the global reset and wasn't. The global reset is basically a "free" reset that occurs at power-on. It's free because it uses dedicated reset distribution, rather than distributing reset like other signals. Using the global reset, I went from banging my head against timing constraints I couldn't meet to beating them by a sizable margin. Next up... checking it all in, then doing some regression testing in simulation.
Now, if we can just get the XP10 clock skew problem worked out, I'll be able to test this in real hardware. -- Timothy Normand Miller http://www.cse.ohio-state.edu/~millerti Open Graphics Project _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
