Altium Designer Makes Ultra-High-Performance Design Move Faster at Spectrum Integrity Spectrum Integrity designs ultra-high-speed digital, most of the effort of making accurate BOMs. RF, and microwave PCBs which, at 20 to 110 GHz Spectrum Integrity also found it straightforward and beyond, are among the most challenging to customize the Altium Designer environment for applications in industry. Its customer design the intricacies of RF design. We added strategic, challenges require a proprietary outside the proprietary improvements to the tool suite to box process. Yet at the same time, the company make them very powerful and efcient for RF and must interface with industry standard component ultra-high-speed digital design, says Ingham. To libraries as well as the design review processes of streamline interaction with RF analysis, it exports its clients. board designs in Gerber data into a 3D eld solver. To design such esoteric designs, the company relies After completing analysis, Altium Designer reads on a collection of very specialized tools. The native the les back in AutoCAD or DXF format, an easy schematic capabilities in such tools have proved process that retains net intelligence within the completely unusable. Spectrum Integrity had to integrated tool suite. Also, Spectrum Integrity rely instead on a third-party schematic tool that reports that creating custom footprints, with prevented synchronization of layout and schematic non-standard features, is much easier in Altium and no cross-probing capability. The process had Designer than its old tool suites. become too disjointed.

The frequent client reviews updating of split power planes during the course were a tedious and long process. of design, saving manual retouching of those planes during design changes.
