VCD Waveform Analysis

What problem does it solve?

This skill helps engineers quickly analyze Value Change Dump (VCD) waveform files from SystemVerilog simulations, enabling faster clock detection, reset tracing, and signal timing diagnosis.

Core Features & Use Cases

• VCD Parsing: Understands VCD structure and extracts signals, times, and values.
• Clock Detection: Identifies clock nets and measures frequency and duty cycle.
• Signal Tracing & Timing: Follows data through modules and analyzes setup/hold, delays, and propagation.
• Anomaly & Debugging: Detects glitches, unknowns (X), and stuck signals for debugging verification failures.
• Use Cases: Verify that your testbenches produce valid timing relationships across clocks and reset deassertion events in SV designs.

Quick Start

Run the sv-waveform analysis on your VCD file to extract clock, reset, and timing insights from the simulation trace.
