I don't totally get it but the fact the MicroWatt core is able to run on an FPGA board like OrangeCrab makes me think it's a quite tiny core. Also, as far as I understand, this core does not exist in silicon but is run on a board (https://www.electronics-lab.com/open-source-dc-scm-compatible-bmc-hardware-platform/ https://www.electronics-lab.com/open-source-dc-scm-compatibl...) with an Artix 7 FPGA.
