AngularJS 4 Trivia Quiz-App

Design-rule check: a GDS layout + a rule deck in, geometry violations out.

The book searcher from bibliographic informations in [openBD](https://openbd.jp/) by [Groonga](http://groonga.org/ja/).

Static timing analysis with signal integrity — WNS/TNS sign-off gate, SI/crosstalk + statistical OCV.

Layout-vs-schematic: SPICE netlist comparison with clear divergence diagnostics.

Headless GDS layout viewer: a GDS in, a layered SVG out — with optional violation overlay.

Closed measurement kernels: coherent single-tone spectral (SNR/SINAD/THD/SFDR) and AC transfer (gain, bandwidth, unity frequency, phase margin).

Power analysis: per-instance leakage + dynamic power and the activity map that closes char -> power -> em-ir.

Combinational logic equivalence check: two gate-level netlists in, an equivalence verdict (with counter-example) out.

Antenna ratio sign-off over the routed design database: PAR/CAR/PSR/CSR per layer against the LEF limits, including the diffusion-dependent (PWL) form.

A full stack PWA text editor

Hierarchical macro placement correlated against OpenROAD's mpl: clustering, coarse shaping, annealing, boundary push, orientation, commit and track snapping — over the OpenDB database.

Web application built with React, Recharts, and the OpenDB API, allowing users to explore trivia question data visually.

Liberty characterization — SPICE + PDK models to .lib (NLDM + CCS), parallel-SPICE orchestration.

STA-driven Vt swapping: trade threshold-voltage flavors (iso-footprint) to cut leakage while holding timing, or to close setup.

Post-route hold-fix ECO: insert series delay cells on hold-violating capture pins to close hold timing.

Loom engine: file-level multi-output technology re-mapping (mockturtle emap) via the vyges-emap driver

Detailed placement over the OpenDB design database: placement legality checking.
