Ansys - Nexxim

In the world of high-frequency electronics and high-speed digital links, standard SPICE simulators often struggle. They are slow, prone to convergence failures, and cannot handle the massive parasitic extraction files generated from modern PCBs or IC packages.

An engineer designs a GaN power amplifier and a SAW filter. Nexxim’s Harmonic Balance engine rapidly simulates intermodulation distortion (IMD) and adjacent channel power ratio (ACPR)—simulations that would be impractical with standard time-domain methods. ansys nexxim

For a solo hobbyist or basic PCB designer, Nexxim is overkill. But for a defense contractor, a server manufacturer, or a wireless infrastructure company—where a single simulation failure means a $100,000 respin—Ansys Nexxim is indispensable. In the world of high-frequency electronics and high-speed
