Where ANVIL is going

Folded-cascode and telescopic OTAs, fully differential variants with common-mode feedback, and LDO regulators.

Mismatch analysis and Monte Carlo runs, with the same per-number traceability as today's compliance table.

Input-referred noise as a spec, measured and graded like the others.

Check a sized design with parasitics extracted from its layout, not only at schematic level.

Size several topologies against one spec in a single run and compare their worst-case compliance in one table.

Load your own model cards and corners, including a foundry PDK, with simulation on infrastructure you control so the models never leave your network.

Chain spec extraction, sizing, corner sweeps and report generation into one workflow. Steps pass typed results (spec, netlist, simulation result, report), and workflows are stored as versioned text files you can review like code.

Points where a workflow pauses for a designer to confirm extracted specs, approve a simulation budget or pick a topology. A gate pauses only its own branch, and each decision is recorded with its evidence.

When a requirement changes, find the results that depended on the old value, re-check stored simulation data against the new limit without re-simulating, and re-run only what is no longer valid.

A graph from each requirement through specs, design variants and simulation evidence to the decisions and reports built on them, showing what any result depends on and what depends on it.

Reuse a stored result when the netlist, models and simulator version match a previous run, instead of simulating it again.
