How do you assign a differential pair in Altium?
To create a differential pair object in the PCB editor, click the Add button in the Differential Pairs region of the PCB panel in Differential Pairs Editor mode. In the resulting Differential Pair dialog, select existing nets for both the positive and negative nets, give the pair a name then click OK.
How do you make xSignals in Altium?
Select the source component, then right-click on the selected component and choose the xSignal » Create xSignals between Components command from the context menu. The Create xSignals Between Components dialog will open, with the chosen source component selected.
What is critical length in the PCB design?
For digital signals, the critical length lc is defined as the line length over which the signal propagation time is half of the fastest rise time of the signal pulses. If tr = fastest rise time of the digital signal, the time of the propagation of the signal over the length lc is tpd.lc = tr/2 (by definition of lc).
How to perform differential pair tuning in Altium Designer?
You can encode permissible length mismatches as design rules as part of controlled impedance routing, or you can manually perform differential pair tuning using a variety of meandering styles. Here’s how this works in Altium Designer.
How to set Min joint in Altium Designer 21?
Min Joint – minimum length of the first colinear track segment placed before the first tooth is created. Single Side – create the tuning pattern so that it only projects in one direction from the original route path. Press the S shortcut during placement or interactive editing to toggle the option on or off.
How are length tuning segments added in Altium?
Length tuning segments are added by simply wiping the cursor along the route path, with the dimensions and positions of the various tracks and arcs that make up the tuning segments automatically calculated and inserted by the length tuning algorithm.
How to increase or decrease amplitude in Altium?
Press the or shortcut keys to interactively decrease or increase the Amplitude, in increments of Amplitude Step. (Amplitude) Step – the amount that the Amplitude will change Space – the distance between the centerlines of adjacent accordion switchback paths.
