Transplantation of xuantie e906 -- fanwai 0: Construction of xuantie c906 simulation environment

Darksteel E906 transplant ---- Off the coast 0：C906 Simulation environment construction

1. Darksteel C906 and E906 The steps to build the simulation environment are the same , See my Another blog ：E906 transplant ---- Project introduction 、 Development environment and experimental platform construction .

2. Flathead tool chain and E906 identical ： Flathead brother compiler tool chain https://occ.t-head.cn/community/download?id=4049193882418745344 ;

3. The project package is still flat Head brother official github On ：https://github.com/T-head-Semi ;

4. Pay attention to the settings csh Environment variables of , First E906 and C906 The tool chain is the same without change （ namely TOOL_EXTENSION ）, Source package variable address E906 and C906 Are different and all used CODE_BASE_PATH Variable , so .cshrc Need to comment out the previous E906 Of , Replace it with a new one C906 Of

#setenv CODE_BASE_PATH /home/ICer/ic_prjs/opene906-main/E906_RTL_FACTORY
setenv CODE_BASE_PATH /home/ICer/ic_prjs/openc906-main/C906_RTL_FACTORY
setenv TOOL_EXTENSION /home/ICer/Xuantie_tools/Xuantie-900-gcc-elf-newlib-x86_64-V2.2.5/bin

5. Run one coremark , use vcs Much faster ,iverilog Very slowly ：
