SoC-Simulator

A Verilator based SoC simulator that allows you to define AXI Slave interface in software.

Features

Device Support:

• UARTLite

Easy to co-simulate with cemu.

Quick Start

• Refer to Makefile and modify variables TOP_NAME, INC_FILE, INC_DIR and INC_PATH:

  • TOP_NAME: the name of your CPU top module
  • INC_FILE: all RTL code files included in your design
  • INC_DIR: home directory of RTL header files
  • INC_PATH: cemu core home

• Makefile targets:

  • default: generate executable simulation module obj_dir/V$(TOP_NAME)
  • run_func: run function tests, diff with golden trace in test/func/golden_trace.txt with AXI latency 34 (read the source code for detail)
  • run_perf: run all performance tests without diff test
  • diff_perf: run all performance tests diff with cemu
  • diff_{bitcount, bubblesort, ..., stringsearch}: run specified performance test and diff with cemu (suggested)

• Makefile variables:

  • T: dump waveform when T is set to y in repo home directory (note: you'd better dump waveform after the module report Error since the waveform file requires large disk space.)

• Examples:

  • run function tests and dump waveform file: make run_func T=y
  • run crc32 and diff with cemu: make diff_crc32
