Getting Started with Symphony Team Design Symphony Team Design Commands October 2019 81 Product Version 17.4-2019 Interactive Routing Tasks Routing supports following commands for: ■ Manual routing: add connect, slide, delete, and delay tune ■ Routing cleanup: change, custom smooth, vertex, and delete vertex ■ Cutting clines, lines, and shapes: delete by line and delete by rectangle ■ Moving and copying clines and vias: move, copy, and change ■ Adding phase bumps to either member of the differential pair: phase_tune ■ Creating bounding shape: create bounding shape ■ Creating and copying fanout clines and vias: create fanout and copy fanout ■ Spreading clines between adjacent plane layer voids: spread between voids (PCB Designer) and spread clines (APD+) Integrated Analysis and Checking ■ Analysis Flow: Performs analysis for electrical issues on the selected nets or the directed groups and reviews results tables and plots with cross-probing to canvas. Visions provide graphical overlay on routing layers for direct feedback. (This feature is available with High-Speed option). ❑ Impedance Analysis: Runs an impedance simulation or load analysis results from a previous simulation, navigate to areas of interest with cline segment color coding on the canvas including enhanced datatips. ❑ Coupling Analysis: Runs a coupling simulation or load analysis results from a previous simulation, navigate to areas of interest with cline segment color coding on the canvas including enhanced datatips. ❑ Crosstalk Analysis: Runs a crosstalk simulation or load analysis results from a previous simulation, navigate to areas of interest with cline segment color coding on the canvas including enhanced datatips. ❍ Requires Allegro Sigrity SI license ❑ Return Path Analysis: Runs a return path simulation or load analysis results from a previous simulation, navigate to areas of interest with return current flow visualized on plane layers. ❍ Requires Allegro Sigrity SI license
