Note also that any unrouted nets will use the Manhattan length between pins to calculate a track length estimate for analysis purposes. This can be checked by selecting Project » Component Links.

You can now have some (or none) of the schematic components in the PCB but any that have been placed must be linked with Component Links. This will allow both reflection and crosstalk analysis to be performed.įrom the PCB Editor, select Tools » Signal Integrity which will proceed through the same process as that described above for the schematic only mode. Note that you could also run Signal Integrity from any of the schematic documents in the project and it will have the same effect as running it from the PCB. When running a Signal Integrity analysis from a PCB document, the PCB must be part of a project along with the related schematics. Running a Signal Integrity Analysis from a PCB Project This will first allow you to setup any necessary signal integrity models and then show the signal integrity panel from where you can view initial results and perform further analysis. These rules can be added as PCB Layout directives or Parameter Set directives on nets in the schematic.įrom the Schematic Editor, with the schematic open, select Tools » Signal Integrity from the menus. The Signal Integrity Analyzer also reads the PCB design rules from the schematic for the stimulus and supply nets. When running in schematic only mode, default average track length and impedance can be defined using the Signal Integrity setup options. There is no crosstalk analysis available because routed nets are required for this analysis.

The schematic must be part of a project, as analyses will not run on documents opened as Free Documents.

You can perform a Signal Integrity analysis on the design using only a schematic whenever there is no PCB as part of the project. Running a Signal Integrity Analysis from a Schematic Only Project When Signal Integrity issues are found, Altium Designer shows you the effects of various termination options, allowing you to find the best solution before modifying your design. Signal Integrity screening is built into the Altium Designer design rules system, allowing you to check for Signal Integrity violations as part of the normal board DRC (Design Rule Checking) process. This allows you to address potential Signal Integrity issues, such as mismatched net impedances, before committing to board layout.įull impedance, signal reflection and crosstalk analysis can be run on your final board (or a partially routed board) to check the real-world performance of your design. Preliminary impedance and reflection simulations can be run from your source schematics prior to final board layout and routing.

Based on a fast reflection and crosstalk simulator model, the Signal Integrity Analyzer produces accurate simulations using industry-proven algorithms. Altium Designer's Signal Integrity Analyzer uses sophisticated transmission line calculations and I/O buffer macro-model information as input for simulations. Signal Integrity OverviewĪltium Designer includes pre-layout and post-layout Signal Integrity analysis capabilities. With Altium Designer, you can analyze the Signal Integrity performance of a PCB from either the Schematic or the PCB Editors, evaluate net screening results against predefined tests, perform reflection and crosstalk analysis on selected nets, and display and manipulate the waveforms in the Waveform Analysis window. It covers setting up design parameters like design rules and Signal Integrity models, starting up Signal Integrity from the Schematic and PCB Editors, configuring the tests to be used in the net screening analysis, running further analysis on selected nets, terminating the signal line, setting preferences and working with the resulting waveforms. This tutorial looks at performing Signal Integrity (SI) analyses.
