Clash utils

A collection of reusable Clash designs/examples.

See here and here for projects built using components in this library.

Includes:

• Binary to BCD conversion, BCD arithmetic that efficiently utilises the carry chain.
• A bitonic sorting network
• CORDIC for calculating trigonometric functions
• CRC calculation
• A Cuckoo hash table
• Divider
• FFTs
• A FIFO
• FIR, IIR and CIC filters
• Gray code conversion
• Hamming code encoding/decoding
• LFSRs
• Multi port block rams
• Multipliers
• Prefix sums, Carry lookahead adders, Carry select adders and Carry save adders
• Pseudo LRU trees
• Regular expression matching
• Scrambler
• SHA3 and AES
• Sine wave generation
• Utilities for streaming data

Each design has a Hspec testsuite/specification in the /tests subdirectory. A handful of designs have formal properties in the /formal directory.

Status

FPGA proven designs are indicated in the module documentation.
