【FPGA】Synopsys vcs2018仿真问题汇总

1.重启后lisense问题

【问题原因】

可能是lmgrd服务不正常导致的，这边通过下面几个步骤解决

1. 切换到root用户

su root

2. 彻底关闭lmgrd服务

lmdown ps -aux | grep lmgrd kill -9 xxxx

3. 验证本地lisence

sssverify /usr/lyq/software/Liscen/Synopsys.dat

4. 修改.bashrc文件

5. 重新source

source .bashrc

6. 3-5min后启动lmli

lmli

7. 修改.bashrc文件

8. 重新source

source .bashrc

9. 启动verdi

verdi

2. 运行vcs仿真报错

ld returned 1 exit status

【问题原因】

虚拟机重启导致g++/gcc版本切换到默认版本，通过编译指令或设置默认版本解决

vcs2018需要使用的g++/gcc版本均为4.8.5

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 100 sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.8 100

3. 未定义系统任务

在使用make进行vsc仿真编译中出现未定义系统任务问题

undefined system task called to $fsdbDumpfile

【问题解决】

需要增加下面的Verdi编译文件：

 -P ${VERDI_HOME}/share/PLI/VCS/LINUX64/novas.tab ${VERDI_HOME}/share/PLI/VCS/LINUX64/pli.a

4.未定义参考变量

/usr/bin/ld: *** undefined reference to `vfs_set_dir_map’

【问题解决】

在vcs编译中增加

-LDFLAGS -Wl,--no-as-needed
