15. Programmable Logic Array.

All the bits of the respective devices are accessible individually as standard array accessing method in computer programming and collectively as a BUS, bits of different outputs of different bits can be grouped together and used accordingly.
All the commands to work with the devices are available in Github repository,
User can also submit Updates, Bug reports, Programs coded in the HDL in Github as well.


Digi-Arsenal – A Computational Simulation Laboratory

Digi-Arsenal is a laboratory for Computer Science.
It is built for execution, observation, and control.

This application is designed to provide a structured environment where abstract computational concepts are transformed into explicit, observable systems. Digi-Arsenal emphasizes mechanism over narration, enabling users to interact directly with the foundations of computation.

The app is paid, ad-free, and built for lifetime use, prioritizing rigor over convenience.

Design Philosophy

Digi-Arsenal rejects passive instruction.

Instead, it provides:

Deterministic execution

Logical transparency

System-level interaction

Concepts are not merely described; they are constructed, executed, and examined.

Core Capabilities
Computational Terminal

Program execution in a controlled, stepwise environment

Clear visibility into logical flow and state transitions

Designed to resemble an authentic computational workspace

Digital Logic & Hardware Simulation

Gate-level and combinational logic modeling

Adders, comparators, and foundational circuits

Bit-level observation for precise understanding

Intended Audience

Digi-Arsenal is developed for:

Computer Science and Engineering students

Educators seeking demonstrable computational models

Learners pursuing long-term mastery rather than short-term certification

Sustained Development Model

Digi-Arsenal follows a disciplined evolution:

Community-driven feature proposals

Structured contribution through open platforms

Recognition of meaningful contributions through an internal Hall of Record

The system evolves, but the principles remain fixed.

Access Model

One-time purchase

No advertisements

No behavioral tracking

Lifetime access
