What is a list of all softcores that were designed purely using VHDL?

• microwatt

  4 552 9.2 Verilog

  A tiny Open POWER ISA softcore written in VHDL 2008

  My knee-jerk reaction was "No" since it's IBM POWER. But then I read that the POWER architecture and ISA support bi-endian, and then I also gather from https://github.com/antonblanchard/microwatt/search?p=1&q=endian that the microwatt starts up in little-endian (LE) mode. In addition, the examples are compiled for LE mode: https://github.com/antonblanchard/microwatt/blob/e40e752b9ab602f5ce1eb79be1fe96932558830d/hello_world/Makefile#L12

• lxp32-cpu

  1 50 0.0 Assembly

  A lightweight, open source and FPGA-friendly 32-bit CPU core based on an original instruction set

  

  I used this one https://github.com/lxp32/lxp32-cpu as base for building a RISC-V softcore.
