How do you manage your trace lengths?
Too often I see people just using straight length to manage their board timing. Or take it one step further and turn length into propagation delay.You know, 1 inch is about 166ps. Which is true, but nowhere near the complete picture for timing. If you think about it, the whole reason we have length constraints is to make sure data arrives at a certain time. That means that the signal switches above … Read More
