HARDWARE SYSTEM DESIGN -2

A2B Systems delivers advanced Hardware Engineering.
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 Capture3D 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

Clear Foundations

Strong documentation and reviews ensure downstream engineering accuracy.
