Error while building sodor emulators, riscv-sodor

Asked 2019-Sep-30 at 14:19

I installed riscv,riscv-gnu-toolchain and riscv-tools and want to get riscv-sodor. To do that i followed the steps from https://github.com/librecores/riscv-sodor , succesfully installed verilator and front-end server but after that i have to build sodor emulators and on first step by doing make command i got this error

That specific error is due to verilator not being installed and on your $PATH.

QUESTION

Rocket chip simulation shows unexpected instruction count

Asked 2018-Jul-20 at 21:36

The following two code snippets differ only the value loaded into the x23 register, but the minstret instruction counts (reported by a Verilator simulation of the Rocket chip) differ substantially. Is this a bug, or am I doing something wrong?

The read_csr() function is from the RISC-V Frontend Server Library (https://github.com/riscv/riscv-fesvr/blob/master/fesvr/encoding.h), and the rest of the code [syscalls.c, crt.S, test.ld] is similar to the RISC-V benchmarks (https://github.com/riscv/riscv-tests/tree/master/benchmarks/common).

I have checked that the compiled binaries contain the exact same instructions, except for the difference in the operands.

Dividing 0x0fffffff by 0xff, repeating 1024 times: 3260 instructions.

The problem was resolved at https://github.com/freechipsproject/rocket-chip/issues/1495.

Servicing the debug interrupt, which is apparently used by the simulation to know whether the benchmark has finished executing, caused the differences in the instruction count. The verbose log produced by Verilator shows the debug address range (0x800 onwards) being injected at different points during the execution.
