Where is Simpoint simulated?

[qqli579]

你们用spec2006 的simpoint在哪里进行仿真的？是在软件仿真器（比如gem5）上仿真还在fpga平台（比如EMU和帕拉丁）上仿真？
有没有在FPGA平台上跑过simpoint？

[TRANSLATION] Where do you simulate Simpoint using SPEC2006? Is it simulated on a software simulator (such as gem5) or on FPGA platforms (such as EMU and Paladin)? Have you ever run Simpoint on an FPGA platform?

我们通常使用 NEMU (ISA 模拟器）来生成 Simpoint Checkpoint，然后在 Gem5 或 emu（RTL 仿真器）上来运行这些 checkpoint。
目前应该并没有在 FPGA 上运行过 checkpoint。

更多信息，请参见香山文档和我们之前的报告：

• 香山官方文档 - Simpoint
• 香山的报告
  • RISC-V Checkpoint + Sampling estimate the SPEC score in hours
  • 香山微结构模拟器 XS_GEM5

We usually use NEMU, which is a ISA emulator, to generate Simpoint Checkpoints, then run these checkpoints on Gem5 or emu (RTL simulator).
As far as I know, we have not run checkpoints on FPGA.

For more infomation, please refer to XiangShan documents and our previous talks:

香山 EMU 的运行速度大约每秒 0.5~2 千条指令；Gem5 我没有具体数据。
