Hello,
My name is Eduardo Michel Deves de Souza, in the last year I worked on my final coursework at my college, which is based on the RARS simulator, it is a web simulator for RISC-V, using RV32I, the objective is that students at the University of Vale do Itajaí use in class. I hosted it on GitHub pages:
