State College, PA. Remcom has announced circuit cosimulation and expanded signal integrity capabilities in the latest update to its XFdtd 3D electromagnetic simulation software.
Circuit co-simulation facilitates a more realistic analysis of device performance by including imported circuit components within the electromagnetic simulation. The schematic for a desired component may be imported into XF via a netlist file, with support for Spice elements such as resistors, capacitors, inductors, coupled inductors, and subcircuits. Netlist components can also be assigned as a matching circuit embedded within a feed, simplifying matching network design.
This release also introduces a nodal waveguide interface with enhanced options for computing S-parameters. A user-defined reference impedance enables renormalized S-parameters to be computed for transmission lines that would typically display an impedance mismatch. A nodal excitation is also available for simulations that do not require S-parameters to be collected.
