Popular Tools
The most-used engineering utilities on the platform
Hex / Bitfield Decoder
Decode any hex register value into its constituent bit fields with a visual bit map. Define custom fields or use presets.
PCIe Bandwidth Calculator
Calculate raw and effective PCIe bandwidth for Gen1 through Gen6 with configurable lanes, encoding, and protocol overhead.
PCIe LTSSM Decoder
Paste LTSSM state logs to analyze transitions, detect repeated recovery events, and get engineering debug guidance.
DDR / LPDDR Bandwidth Calculator
Calculate theoretical bandwidth for DDR4, DDR5, LPDDR4, LPDDR5, and LPDDR5X with configurable data rate and bus width.
Engineering Unit Converter
Convert between frequency, data rate, time, voltage, current, power, and resistance units. Supports decimal and binary prefixes.
More Tools
Convert between hex, decimal, and binary. Perform byte swaps and endianness conversions for 16/32/64-bit values.
Compute CRC8, CRC16, CRC32, XOR, and sum checksums with configurable polynomial for hex or ASCII input.
Enter multiple power rails with voltage and current to compute per-rail and total power consumption.
Calculate power, voltage, or current from any two known values. Includes energy and battery runtime calculations.
Built for Engineers
Not a collection of random calculators. A professional engineering workbench where tools are interconnected and calculations are accurate.
Instant Computation
All calculations run in your browser. No round-trip to a server, no waiting.
Privacy First
Your hex dumps and logs never leave your device. No data collection on inputs.
Protocol Accurate
Based on public specifications from PCI-SIG, JEDEC, NVM Express, and MIPI.
Extensible
A common tool framework lets new decoders and calculators be added rapidly.
Free vs Pro
Free tools are genuinely useful. Pro adds advanced analysis and AI assistance.
