About LibFPGA

LibFPGA is a free toolbox for FPGA and digital-design engineers: interactive calculators, HDL code generators and reference cheatsheets that solve the small, recurring problems of RTL work — sizing a FIFO, generating a parallel CRC, picking a baud divisor — in seconds instead of minutes.

Principles

• Instant and free. No signup, no paywall on the tools.
• Show the math. Every calculator explains how it got its answer, so you can trust it — or catch our mistakes.
• Verify everything. Generated code is produced by tested algorithms (e.g. the CRC generator is checked against a bit-serial reference), but you should always simulate before you ship. So should we all.
• Respect your privacy. No tracking cookies, no fingerprinting. See our privacy policy.
