HARDWARE SYSTEM DESIGN

A2B Systems delivers advanced Hardware Engineering.

Hardware Design and Development

Comprehensive Hardware Engineering Services covering design, simulations, analysis, quality assurance, manufacturing, and program management.
From concept to certification and production, we ensure reliable, high-performance electronics with a seamless transition to manufacturing.

Clear Foundations

Strong documentation and
reviews ensure downstream
engineering accuracy.

Specification &
Requirements

We formalize requirements through:

  • Product Requirement Document (PRD): Defines functional, performance,
    safety and regulatory expectations.
  • Hardware Subsystem Requirement Document: Breaks product-level
    needs into measurable hardware requirements.
  • Customer Review Cycles: Requirements are validated early to prevent
    downstream redesign

Design Process
Overview

We follow a structured, repeatable process:

  • Requirement Gathering
  • High-Level Architecture
  • Component Selection
  • Power Budget Management
  • Detailed Design
  • Library Development
  • Schematic Capture & 3D Visualization
  • PCB Layout Design
  • Design Reviews
  • Prototyping
Structured Execution

A disciplined multi-stage process
reduces errors and accelerates
development

Strong Blueprint

Architecture defines your
product’s performance,
scalability, and reliability.

High-Level
Architecture

We define:

  • Compute core (MCU/MPU/FPGA/AI accelerator)
  • Memory paths
  • Signal flows
  • Power tree
  • Connectivity options

Component Selection
& Evaluation

We select:

  • Long lifecycle components
  • Multi-source equivalents
  • Supply chain-stable Ics
  • Vendor-recommended alternatives
Structured Execution

Component choices directly
impact cost, performance, and
long-term availability.

Stable Power

Proper power planning ensures
thermal stability and reliability.

Power Budget
Management

We calculate:

  • Load per rail
  • Peak vs continuous current
  • Duty cycles
  • Sequencing
  • Thermal dissipation necessities

Detailed
Design

We select:

  • Pin mapping
  • Decoupling strategy
  • EMC-friendly topology
  • IO protection
  • Clock & reset architecture
Precision Engineering

Detailed design links
architecture with
implementation precision.

Clean Libraries

Clean libraries eliminate
footprint, assembly, and rework
issues.

Library
Development

We create:

  • Footprints
  • Symbols
  • 3D models

All compliant with IPC standards and DFM guidelines

Schematic
Capture

We do:

  • Hierarchical schematics
  • High-speed interface rules
  • Controlled return paths
  • Vendor guideline compliance
Design Foundation

A professional schematic is the
foundation for a successful PCB
layout.

Mechanical Fit

Mechanical-electronic alignment
avoids enclosure and fitment
issues.

3D
Visualization

We generate:

  • Step models
  • Mechanical alignment checks
  • Connector orientation validation
  • Heat sink placement feasibility

Prototyping
Stage

We produce:

  • Built prototypes (SMT, BGA capable)
  • Bring-up logs
  • Early firmware test points
Early Validation

Prototypes validate real-world
behavior before scaling.

Core Verification

Early testing ensures stable
operation of core product
functions.

Electrical & Functional
Testing (EFT)

We validate:

  • Power rails
  • Communication buses
  • Sensor accuracy
  • Logic correctness
  • Timing and stability
