====== simulation ======


指定stdcell,io,memory等模块的仿真模型

<code>
set_simulation_library_source -f ./all_model.f
</code>

设置VCS安装目录

<code>
setenv VCS_HOME /tools/syn/vcs_mx-2022.6-SP1/
</code>

运行仿真命令指定仿真器是vcs

<code bash>
run_testbench_simulations \
  -parallel_simulations 10 \
  -simulator vcs \
  -compilation_options {-kdb +define+debussy} \
  -simulator_options {-kdb -debug_access+all -debug_region=cell+lib -lca} \
  -extra_verilog_files {../rtl/b.v ../rtl/c.v} \
  -extra_top_modules module_name_list  \
  -use_design_view_per_simulation on
</code>



另外需要说明的是如果是前仿真，因为没有sdf的缘故出现时序违例的问题导致仿真不通过，可以进入tessent自动生成的仿真目录修改vcs.simulation_scrip，在vcs命令添加nospecify，或no_notifier和notimgcheck。


<code bash>
