Development on Ibex started in 2015 under the name "Zero-riscy" and "Micro-riscy" at the ETH Zurich and University of Bologna, where it was part of the PULP platform. In December 2018 lowRISC took over the development. Luca Benini of the ETH Zurich sits on lowRISC' board.

November 2018, and is available
