Workflow
Run the TT-CoSign pipeline against the active project's files.
DIE MODEL BINDINGS (optional — per-cluster evaluator selection)
By default every cluster uses the built-in synthetic evaluator. Bind a cluster to a fitted Die Model Studio model to use its real surrogate instead — the evaluator TT-cross and Sensitivity analysis actually run against changes.
| Cluster | Die type | Evaluator |
|---|
01 · IMPORT — PSEUDO-FLOORPLAN
02 · INTERACTION GRAPH
03 · TREEWIDTH DECOMPOSITION
04 · TENSOR-TRAIN COMPRESSION
05 · COMBINATORIAL SEARCH
MULTI-OBJECTIVE PARETO FRONTIER (YIELD vs. POWER)
06 · SELECTED ASSIGNMENT & CERTIFICATE
07 · SENSITIVITY ANALYSIS (PCE + SOBOL INDICES)

Die Model Studio
Fit a reusable IP-block/die surrogate model: active-learning-selected simulation points + sparse Polynomial Chaos Expansion, in the style of QUINSIM's UQ workflow — a fast, accurate stand-in for repeated SPICE sweeps.
FIT A NEW DIE MODEL
Uses the bundled synthetic device evaluator as a stand-in for a real SPICE call (see Help for how to plug in a real simulator). Watch progress live in the Engine Console below.
