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.

FPGA proven designs are indicated in the module documentation.
