Frequency-domain S-parameters
An adaptive frequency sweep solves only the points it needs and interpolates the rest.

TransWeave
GPU-native full-wave signal integrity for high-speed interconnects.
A browser workspace for RDL, package and PCB channels. Draw the stack and layout, solve it with a layered-media Method of Moments on GPU, and read back S-parameters, waveforms and the eye.
Opens with a differential-pair demo model; build any model in the editor. Guests get 2 Fast runs and 1 Balanced run.

Workflow
Stack and layout in, S-parameters and eye out.
- 01
Draw
Define the dielectric stack and draw the layout in the browser, or import GDS.
- 02
Run
Run FD for S-parameters or Run TDPS for time-domain periodic responses.
- 03
Read
Inspect S-parameters, waveforms and the eye; export results.
Modeling
The geometry real channels are made of.
Any dielectric stack
Arbitrary layered dielectrics on a ground plane.
Traces and polygons
Sheet or finite-thickness copper, plus shield layers.
Vias and bumps
Vertical transitions between layers and to the package.
GDS import / export
Bring layouts in from GDS and write them back out.
Analyses
From S-parameters to a link verdict.
TDPS time domain
Time-domain periodic sequence: periodic waveforms computed directly by the solver.
Periodic waveforms
Periodic eye
The eye diagram from periodic responses, with far fewer solves than an FD-based eye.
42 TDPS vs 240 FD solves
SerDes link check
Tx pulse, CTLE, FFE, DFE and jitter applied to the channel for a go / no-go answer.
