Enhanced Polar Grid Support

Component placement is one of the main steps in board design. And in specific boards of a circular shape, it is convenient to use a polar grid for the location of components. Altium Designer 21 brings several improvements to the polar grid. Now, when a component is positioned in a polar grid, its properties additionally display location coordinates relative to this grid. Using them, you can quickly arrange the components in the right places. And moving the component off the grid, polar coordinates are automatically disabled.

New PCB Length Tuning Patterns

Length matching is a critical element of high-speed design, usually solved by carefully tuning the lengths of critical routes. This release sees extensive improvements to both single-sided and differential pair length tuning capabilities. Length tuning now supports all three popular tuning patterns: Trombone, Sawtooth, and Accordion. If you are working with lower speed or lower frequency signals, you can get away with trombone tuning. For the Trombone patterns, the polygonal area that the pattern is constructed within can be thought of as a sleeve.
