If you understood the output skew from your transmitter, and your setup and hold times for your receiver you could come up with a number for the acceptable routing delay.

That's really not bad at all considering your 5.882ns clock period. Subforum : DipTrace PCB Layout ( Total topics 323 Total posts 1156 ) Making PCB Layouts, Manual routing, Auto-routing, Copper pouring, Updating from. So a 1 inch difference will skew a data signal from clock +/- 150ps. Propagation time for a top layer trace, a microstrip is about 150ps/in. KICAD, Merlin PCB Designer,FREE-PCB, TinењњAD, WINQCAD,Pulsonix, DIPTRACE. Click the Trace Task drop-down arrow and click Trace Downstream. clearances, minimum traces and spaces so your designwill make it through. Click to place flags at each point from which you want to trace downstream. it only does the segment so you will have to keep doing it to cover. Click the tool palette drop-down arrow on the Utility Network Analyst toolbar and click a flag tool button ( or ). Right click on trace and choose segment layer and there is an option to convert the segment of the trace into a jumper wire at top or bottom. What would be the worst case timing difference. To place a jumper wire, on any PCB, regardless of layers: You have to run a normal trace from A to B. What would happen if you routed all your data to within one inch of clock. power inputs as one part and each I/O bank into separate parts. You could separate the component into e.g. You have a 170Mhz signal? That's a period of 5.882ns. While there might not be a single right answer for every occasion, some kind of structured approach will beat a mass of undifferentiated pins every time. Of course it's easy to just say well I must match exactly, because then you don't have to think about it :)Д«ut let's think about it for a minute.

Sometimes a manufacturer will tell you this information, other times you must derive it from the input and output timing data of your transmitter and receiver. In ArcGIS 10, Trace can be used when creating new features, cutting polygons. You no longer need to select the feature to trace first, which commonly restricted which edits you could perform. There are several things in a system which eat into this budget, one of which will be your routing. Making PCB Layouts, Manual routing, Auto-routing, Copper pouring, Updating from Schematic. With ArcGIS 10, tracing allows you to perform your edits more productively than before because you can now use it in conjunction with other editing tools. This is usually defined as setup and hold time, or how long before the clock edge your data needs to be valid, and how long after it must stay valid. Your receiver requires a certain timing relationship between clock and data in order to be guaranteed to function correctly. Signals will leave your source, and arrive at your destination with some timing relationship. Length matching is about timing so if you want to know how tightly you have to length match you have to understand the timing budget for your interface.
