• migen

  4 1,235 5.3 Python

  A Python toolbox for building complex digital hardware

  

  I also happen to really believe in RTL design using high-level languages to enable software design techniques such as object orientation. My master's thesis was written entirely in Migen and I think it served me extremely well.

• litex

  30 3,057 9.7 C

  Build your hardware, easily!

  While I think Migen is a really nice library, it's also a pretty dead project, since the main people behind it moved over to Amaranth. It has one large upside in the fact Litex still uses it as the backend and they seem on the fence between moving over to Amaranth or rolling their own HDL library. For me Litex feels very important, but at the same time, my focus is on compute kernels and not some complicated NOCs.

• hVHDL_floating_point

  3 15 7.9 VHDL

  high level VHDL floating point library for synthesis in fpga

  

  The file has 86 lines, but this functionality could be implemented with just 10 lines of code by using a procedure call to create_first_order_filter which can is defined here https://github.com/hVHDL/hVHDL_floating_point/blob/main/float_first_order_filter/float_first_order_filter_pkg.vhd

• hVHDL_fixed_point

  3 22 6.9 VHDL

  VHDL library of high abstraction level synthesizable mathematical functions for multiplication, division and sin/cos functionalities and abc to dq transforms.

  

  How this works in practice can be seen for example in a rom module. https://github.com/hVHDL/hVHDL_math_library/blob/main/sincos/lut_sine_pkg.vhd
