Usage

Step1: Get Started

$ cd C910_RTL_FACTORY
$ source setup/setup.csh
$ cd ../smart_run
$ make help
To gain more information about how to use smart testbench.

Step2: Download and install C/C++ Compiler

You can download the GNU tool chain compiled by T-HEAD from the url below:
https://occ.t-head.cn/community/download?id=3948120165480468480

$ cd ./smart_run
GNU tool chain (specific riscv version) must be installed and specified before
compiling *.c/*.v tests of the smart environment. Please refer to the following
setup file about how to specify it:
    ./smart_run/setup/example_setup.csh

Notes

The testbench supports Verilator(version is better newer than 4.215),iverilog, vcs and irun to run simulation and you can use Gtkwave or verdi
to open the waveform under ./smart_run/work/ directory.

You can get the debugger, IDE and SDK from the url:https://occ.t-head.cn/community/download?id=575997419775328256
