# Industrial Specification: Counter Register

## 1. Technical Definition
A digital storage component within decoder/counter logic circuits that holds and manages count values.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-5 VDC input voltage range, 0-125°C ambient temperature, 0-100 MHz clock frequency**. Failure boundary: **Input voltage exceeding 5.5 VDC causes latch-up, junction temperature exceeding 150°C causes thermal runaway, clock frequency exceeding 110 MHz causes metastability**, Mechanism: **Electrostatic discharge (ESD) at 2 kV HBM threshold causes gate oxide breakdown, alpha particle radiation at 0.001 particles/cm²·s causes soft errors via charge injection, electromigration at current density &gt; 10⁶ A/cm² causes interconnect failure**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Clock signal jitter exceeding 200 ps RMS | 8 | Metastable state propagation causing incorrect count values | Dual-rank synchronizer with 2.5 ns setup/hold time margins and Schmitt trigger input buffers |
| Power supply noise with 100 mVpp amplitude at 10 MHz | 8 | False triggering of counter increments/decrements | On-chip decoupling capacitors (100 nF/mm²) and separate analog/digital power domains with ferrite bead isolation |
