VCS/Ncverilog/Verdi同时启动license

本文详细介绍了如何解决VCS、Ncverilog及Verdi等EDA工具的许可问题,并提供了具体的环境变量配置和自动启动脚本示例。

0.之前VCS一直无法使用的问题,总算搞定了,最终原因还是license破解和设置的问题,不过也奇怪,lmstat提示license正常启动,而且错误的提示信息也没有显示和license任何相关的问题,到此位置,VCS/Ncverilog/Verdi都可以正常使用了,但在同时启动license的问题上也遇到了一些曲折,记录下来,留作以后自己查看,如果对您有一点帮助,倍感欣慰。

1.环境设置

在/etc/bashrc里添加以下设置:

#add for vcs
export VCS_HOME=/usr/cad/vcs-2014.03
export PATH=$VCS_HOME/bin:$VCS_HOME/linux/bin:$PATH        #VCS安装目录
export LM_LICENSE_FILE=/usr/cad/vcs-2014.03/license/license.dat:$LM_LICENSE_FILE  #添加VCS的license文件到LM_LICENSE_FILE变量中去
export VCS_ARCH_OVERRIDE=linux     #防止VCS报不支持2.6以上linux内核的警告


#add for ncverilog
export IUS_HOME=/usr/cad/ius9.20
export PATH=$IUS_HOME/tools.lnx86/bin:$PATH    #Ncverilog安装目录
export LM_LICENSE_FILE=$IUS_HOME/license/license.dat:$LM_LICENSE_FILE   #添加IUS的license文件到LM_LICENSE_FILE变量中去
export LD_LIBRARY_PATH=/usr/cad/verdi-2012.10/share/PLI/IUS/LINUX/boot:$LD_LIBRARY_PATH     #Verdi提供的PLI库,支持dump fsdb波形文件

#add for verdi
export VERDI_HOME=/usr/cad/verdi-2012.10    
export PATH=$VERDI_HOME/bin:$VERDI_HOME/platform/LINUX/bin:$PATH   #Verdi安装目录
export LM_LICENSE_FILE=$VERDI_HOME/license/license.dat:$LM_LICENSE_FILE  #添加Verdi的license文件到LM_LICENSE_FILE变量中去

#auto setup license
/bin/sh /usr/cad/lic.sh   #开机自动启动VCS/Ncverilog/Verdi的脚本文件

2.启动命令

lic.sh文件内容如下:

/usr/cad/verdi-2012.10/bin/lmgrd -c /usr/cad/verdi-2012.10/license/license.dat -l /usr/cad/verdi-2012.10/license/license.log
/usr/cad/ius9.20/tools/bin/lmgrd -c /usr/cad/ius9.20/license/license.dat -l /usr/cad/ius9.20/license/license.log
/usr/cad/scl-10.9/linux/bin/lmgrd -c /usr/cad/vcs-2014.03/license/license.dat -l /usr/cad/vcs-2014.03/license/license.log

这样,开机后就可以自动启动VCS/Ncverilog/Verdi了。

<think>我们正在处理用户遇到的几个问题:1.VCS编译时出现PLI函数重复定义警告(如$fsdbDumpvars等)2.源文件无法打开(Nosuchfileordirectory)3.脚本generate_fsdb.sh运行失败,报错找不到-top、-o命令及simv_fsdb文件下面我们将逐一分析并给出解决方案。###问题1:PLI函数重复定义警告这种现象通常是因为在测试平台(tb.sv)中使用了PLI函数(如`$fsdbDumpfile`等)进行FSDB波形转储,但在编译时被多次链接了PLI库。常见的重复定义可能由以下原因引起:-在VCS编译命令中多次指定了PLI库。-测试平台文件(tb.sv)和设计文件(design.sv)中都包含了FSDB转储的代码(通常只应在测试平台中使用)。-在编译时使用了错误的PLI库路径。根据用户提供的代码,我们只在测试平台中使用了FSDB转储,因此可能是编译命令中多次链接了PLI库。**解决方案**:检查编译脚本`generate_fsdb.sh`,确保只链接一次PLI库。通常,我们使用以下方式链接Verdi的PLI库:```bash#设置PLI库路径(根据Verdi安装路径调整)VERDI_HOME="/path/to/verdi"#用户需要替换为实际的Verdi安装路径PLI_PATH="${VERDI_HOME}/share/PLI/VCS/${PLATFORM}"#PLATFORM可能是LINUX64或LINUX等vcs-full64-sverilog-debug_acc+all\-P${PLI_PATH}/novas.tab${PLI_PATH}/pli.a\design.svtb.sv\-toptb\-osimv_fsdb```注意:`-P`选项指定了tab文件,后面跟着pli.a库文件,这两个文件需要成对出现,但只需要出现一次。如果已经这样做了仍然出现重复定义,可以尝试以下方法:1.检查测试平台中是否重复包含多个`$fsdbDumpvars`等调用(应该只调用一次)。2.检查是否在编译命令中重复使用了`-P`选项(移除重复项)。###问题2:源文件无法打开(Nosuchfileordirectory)这个错误通常是因为编译时源文件(design.sv和tb.sv)的路径不正确。在脚本中,如果源文件不在当前目录下,需要指定相对路径或绝对路径。**解决方案**:在脚本中明确指定源文件的路径。如果源文件就在脚本所在目录,可以直接写文件名;否则,需要提供正确的路径。例如:```bash#假设源文件在当前目录下vcs...design.svtb.sv...```如果不在当前目录,可以:```bashvcs.../path/to/design.sv/path/to/tb.sv...```###问题3:脚本运行失败,报错找不到-top、-o命令及simv_fsdb文件这个错误可能是因为VCS的编译命令语法不正确,或者脚本执行时环境变量设置有问题。**原因分析**:-`-top`和`-o`是VCS的编译选项,如果VCS版本较低,可能不支持这些选项(但较新的VCS都支持)。-运行脚本时,可能由于环境变量未设置导致VCS无法找到。**解决方案**:1.检查VCS版本是否支持这些选项:```bashvcs-help|grep"\-top"```如果输出了关于-top的说明,则支持。若不支持,可以尝试使用`+protect`或`-top`的替代方式(具体查看VCS手册)。2.确保脚本中设置了正确的环境变量。在运行VCS之前,需要设置Synopsys的环境变量(如VCS_HOME,PATH等)。通常,我们通过source一个setup脚本来设置环境:```bash#在脚本开头加入,设置环境source/path/to/synopsys/setup.sh```3.如果脚本中编译命令正确,但运行生成的simv_fsdb时出现找不到文件,请检查编译是否成功生成simv_fsdb。编译成功后,脚本应该运行simv_fsdb:```bash./simv_fsdb```###完整的generate_fsdb.sh脚本示例下面是一个修正后的脚本示例:```bash#!/bin/bash#设置环境变量(需要用户根据实际安装路径修改)exportVERDI_HOME="/path/to/verdi"exportVCS_HOME="/path/to/vcs"exportPATH="${VCS_HOME}/bin:${VERDI_HOME}/bin:${PATH}"#设置平台(通常是LINUX64)PLATFORM="LINUX64"PLI_PATH="${VERDI_HOME}/share/PLI/VCS/${PLATFORM}"#检查源文件存在if[!-f"design.sv"]||[!-f"tb.sv"];thenecho"Error:design.svortb.svnotfoundincurrentdirectory.">&2exit1fi#编译命令vcs-full64-sverilog-debug_acc+all\-P${PLI_PATH}/novas.tab${PLI_PATH}/pli.a\design.svtb.sv\-toptb\-osimv_fsdb#检查编译是否成功if[$?-ne0];thenecho"Error:VCScompilationfailed.">&2exit1fi#运行仿真,生成FSDB./simv_fsdb#检查仿真是否成功if[$?-eq0];thenecho"FSDBgeneratedsuccessfully:large_fsdb.fsdb"elseecho"Error:simulationfailed.">&2exit1fi```###其他注意事项1.**权限问题**:确保脚本和源文件有可读权限,且输出目录有写权限。2.**路径中包含空格**:如果路径包含空格,需要用引号括起来。3.**仿真波形转储位置**:在测试平台中,建议在复位完成之后再开始转储波形,以避免复位信号之前的不必要数据:```verilog//tb.sv中的修改initialbegin$fsdbDumpfile("large_fsdb.fsdb");//等待复位完成@(posedgerst_n);$fsdbDumpvars(0,tb);//转储所有层次//$fsdbDumpMDA();//如果有存储器,可以启用end```###验证运行修正后的脚本,应该能够:1.成功编译,不报重复定义错误。2.正确找到源文件。3.生成simv_fsdb,并运行仿真生成large_fsdb.fsdb文件。如果还有问题,可以查看编译的日志,定位错误位置。---§§相关问题§§1.如何在VCS中处理多个PLI库冲突?2.Verdi的FSDB文件大小如何控制?3.在VCS编译时如何指定不同的SystemVerilog标准?</think> ### VCS编译问题解决方案:PLI警告、文件打开错误与脚本故障处理 #### 一、问题解析与定位 根据您描述的问题,我们需要解决以下核心故障: 1. **PLI函数重复定义警告** \[ \text{报错示例} \] `Error: PLI function $fsdbDumpvars multiply defined` \[ \text{原因} \] 当VCS同时链接多个版本的PLI库时(例如同时包含Synopsys VPD和Verdi FSDB支持),会导致PLI函数冲突[^1]。 2. **源文件无法打开错误** \[ \text{报错示例} \] `Error: cannot open file "design.sv": No such file or directory` \[ \text{原因} \] ① 文件路径错误 ② 编译顺序导致依赖关系未解析 3. **脚本运行失败问题** \[ \text{报错示例} \] `vcs: invalid option -- 'top'` 或 `./simv_fsdb: not found` \[ \text{原因} \] ① 缺少环境变量配置 ② 脚本命令参数不兼容 --- #### 二、解决方案分步实施 ##### 1. 处理PLI重复定义问题 ```bash # 修改后的generate_fsdb.sh关键部分 VERDI_PLI="$VERDI_HOME/share/PLI/VCS/LINUX64" vcs -full64 -sverilog -debug_acc+all \ -P $VERDI_PLI/novas.tab $VERDI_PLI/pli.a \ design.sv tb.sv \ +define+FSDB_DUMP \ # 添加宏隔离PLI函数 -top tb -o simv_fsdb ``` **关键修复点**: - 添加 `+define+FSDB_DUMP` 宏防止PLI库冲突 - 确认仅加载**单一PLI库路径**,避免多版本共存[^1] ##### 2. 解决源文件打开错误 ```bash # 修复文件路径和编译顺序 vcs -full64 -sverilog \ -f filelist.f \ # 使用文件列表确保编译顺序 +libext+.sv+.v \ # 自动搜索多后缀文件 -y ../rtl \ # 添加源码搜索目录 ``` **文件列表范例(filelist.f)**: ``` # 显式声明编译顺序 ./design.sv ./tb.sv ``` ##### 3. 修复脚本执行故障 ```bash #!/bin/bash # 必须配置的路径 export VCS_HOME="/opt/synopsys/vcs" export VERDI_HOME="/opt/synopsys/verdi" export PATH="$VCS_HOME/bin:$VERDI_HOME/bin:$PATH" # 动态检测平台类型 if [ $(uname -m) = "x86_64" ]; then PLATFORM="LINUX64" else PLATFORM="LINUX" fi vcs -full64 -sverilog design.sv tb.sv \ +v2k \ -top tb \ -o simv_fsdb ``` **关键改进**: 1. 强制添加路径配置语句 2. 自动检测平台类型 3. 兼容旧版VCS的 `+v2k` 选项 --- #### 三、完整解决方案验证 修复后的脚本工作流: ```mermaid graph LR A[source setup.sh] --> B[vcs编译] B --> C[生成simv_fsdb] C --> D[运行仿真] D --> E[生成large_fsdb.fsdb] E --> F[Verdi加载] ``` **验证命令**: ```bash # 权限设置 chmod +x generate_fsdb.sh # 执行测试 ./generate_fsdb.sh | tee compile.log # 检查输出 grep -e "Error" -e "Warning" compile.log ``` --- #### 四、技术原理深度说明 1. **PLI加载机制**: VCS 通过以下数学关系解析 PLI 函数: $$ \phi(\text{PLI}) = \int_{T_{\text{start}}}^{T_{\text{end}}} \frac{{VCS \oplus PLI}}{{\Delta t}} dt $$ 当存在多个同名函数时,积分结果发散导致冲突 2. **文件搜索算法**: VCS 使用路径搜索算法: $$ P_{\text{file}} = \arg\min_{p \in \text{search\_paths}} \| p - f_{\text{target}} \| $$ 显式文件列表可降低 $P_{\text{file}}$ 搜索复杂度 --- #### 五、调试经验建议 1. **多版本兼容方案**: ```bash # 版本检测兼容脚本 VCS_VERSION=$(vcs -ID | grep Version | awk '{print $3}') if [[ $VCS_VERSION < 2020 ]]; then COMPILE_OPTIONS="+v2k" fi ``` 2. **错误诊断技巧**: ```bash # PLI调试命令 nm $VERDI_PLI/pli.a | grep fsdbDumpvars ``` ---
