Verilog Useful Functions Library.

This is a list of various functions that can be useful and still because :

• They are OPTIMIZED.
• They are TESTED and PROVED to work.

All this library will be about combinatorial logic for mathematic or related operations :

• Signed and Unsigned saturated arithmetic.
• Signed division by a power of 2.
• Various rounding strategies.

(Sources are HARD TAB 4. GitHub web display may not like it very much.)

Documentation

• Each function is in a separate .v file because of ease of use with Verilator.
• Each function is documented inside the .v file.
• Test code is provided as a reference, but you can trust me for having RUN IT.
