metastability

Flip flop setup, hold & metastability explorer tool

A educational / research implementation of the Avalanche consensus algorithm written in Rust

GEM-Standalone (GEMS3K) Solver of Chemical Equilibria for Coupled Simulation Codes

GEM-Selektor graphical user interface (GEMSGUI)

Library for the analysis of time-evolving graphs

UVM-based SystemVerilog testbench for CDC & Async FIFO: SVA assertions, functional coverage, agents/sequences/scoreboard, and VCS/Questa run scripts.

EDA tool for characterizing the metastability resolution time constant (Tau) of bistable circuits

A mathematical framework for measuring the dynamics of consciousness. The framework uses a composite index of scale-free temporal organisation, cross-frequency organisation, and metastability.

This repository contains the code and data to reproduce the results and figures from the study: Daniel Koch, Ulrike Feudel, Aneta Koseska (2025). Criticality governs response dynamics and entrainment of periodically forced ghost cycles. Physical Review E, XX: XXXX–XXXX.

Code from the study "Ghost channels and ghost cycles guiding long transients in dynamical systems"

This is a vhdl implementation of a toggle-level handshake for clock crossing domains.

Simulation scripts used in the study "Separation of sticker-spacer energetics governs the coalescence of metastable biomolecular condensates"

SRFM Quantum Phase15: Adaptive Structural Survival Metrics and Metastable Basin Dynamics

Asynchronous FIFO with CDC Reliability Analyzer built from scratch in Verilog. Gray-code pointers, 2-FF synchronizers, randomized stress testbench, timing closure on Artix-7 (WNS = +6.31 ns). No IP cores used.

Hardware button debouncer with metastability protection - VHDL synchronizer chains and CDC fundamentals for reliable input handling

Adaptive basin geometry, metastable topology-memory basins, and perturbation-driven structural memory dynamics in SRFM Quantum systems.

Gray-pointer asynchronous FIFO with two-flop synchronisers, verified against unrelated clocks and a behavioural metastability model that the binary-pointer version fails.

Production-ready asynchronous FIFO buffer with independent read/write clock domains for safe CDC operations. Features Gray code pointers, dual flip-flop synchronizers, metastability prevention, and parameterized design. Essential for SoC inter-module communication and multi-clock systems.
