Competitive landscape
Evidence base
Frontier (open questions)
- On which circuit classes and testbenches is the 2,000x speed-up measured, and does the “comparable accuracy” claim hold for transient corner cases such as sharp spikes and long-time settling?
- Does a surrogate trained on one customer’s SPICE data generalise to unseen topologies and process nodes, or must it be retrained per design?
- What fraction of an AMS sign-off flow can drop SPICE entirely, versus using the surrogate only for early exploration with SPICE retained for verification?
- Is there independent third-party benchmarking of surrogate-versus-SPICE accuracy, and what error metric is used?
