+# Spike RISC-V emulator
+
+[Spike], also known as riscv-isa-sim, is a commonly used [RISC-V] emulator.
+
+
+## Installation
+
+- Download `riscv-fesvr` and `riscv-isa-sim` from <https://github.com/riscv/>
+- Apply the two patches in <https://github.com/riscv/riscv-isa-sim/pull/53>,
+ which are necessary in order to have a serial console
+- Compile `riscv-fesvr` and then `riscv-isa-sim`
+
+
+## Building coreboot and running it in Spike
+
+- Configure coreboot and run `make` as usual
+- Run `util/riscv/make-spike-elf.sh build/coreboot.rom build/coreboot.elf` to
+ convert coreboot to an ELF that Spike can load
+- Run `spike -m1024 build/coreboot.elf`
+
