I'm not the person you asked, but I made an educational simulator for RISC-V [0]. The most critical resource even if it is not super convenient is the official RISC-V specification [1] (this is the latest draft as of writing this comment). There are a bunch of open source simulators [2] to look at for reference if you are unsure of how something is suppose to work. I would recommend compiling a C program to RISC-V and looking at disassembled machine code to get an idea for how things are normally done in terms of RISC-V assembly. There isn't any particularly nice documentation that I am aware of, but enough universities teach using it that there should be some resources that would be helpful for making a simulator. I can probably come up with some links if you are serious about making a simulator, but its a little too much effort to do for a drive-by comment.
