IC验证——perl脚本ccode_standard——c代码寄存器配置标准化
发布时间：2024年01月13日
目录
1 脚本名称
ccode_standard
2 脚本路径
/scripts/bin/ccode_standard
3 脚本参数说明
| 次序 | 参数名 | 说明 |
| 1 | address (./rfdig；.；..；./boot) | 指定脚本执行路径（可以为脚本所在路径的任意相对路径） |
| help | 脚本使用帮助，打印说明信息 | |
| 2 | all | 运行脚本后，脚本会解析全部rbus.cfg，并对参数1指定的目录中的.c文件进行寄存器配置代码标准化修改 |
| module_name_seca.cfg | 运行脚本后，脚本会解析参数2指定的rbus.cfg，并对参数1指定的目录中的.c文件进行寄存器配置代码标准化修改 | |
| 示例 | 命令：ccode_standard ?help 输出ccode_standard使用帮助信息 | |
| 命令：ccode_standard ?./rfdig ?rfdig_seca.cfg 对当前路径下的rfdig文件夹及其子文件夹下所有的.c文件中，有关rfdig_seca.cfg中的寄存器配置代码进行标准化修改； | ||
| 命令：ccode_standard ?. ?crg_seca.cfg 对当前路径下的所有文件夹及其子文件夹下的所有.c文件中，所有有关crg_seca.cfg中的寄存器配置代码进行标准化修改； | ||
| 命令：ccode_standard ?. ?all 对当前路径下的所有文件夹及其子文件夹下的所有.c文件中，所有模块的寄存器配置代码进行标准化修改； | ||
| 说明 | 配置文件module_name_seca.cfg是被验模块寄存器的详细配置文件；脚本索引该文件的具体路径为： $PROJ_SRC/design/scripts/rbus_scripts/rbus_cfg/ 使用该脚本前请先gen_rbus； | |
4 脚本操作说明
? ? ? ? 该脚本用于将如下所示的代码标准化，加速ST用例调整，该脚本可以反复多次调用，不会产生异常问题：
- 使用脚本前，首先gen_rbus，source，产生脚本需要解析的rbus.cfg文件，以及环境变量$ENV{PROJ_SRC}；
- 根据脚本存放路径，指定脚本工作目录，如下例所示，脚本存放于case目录，我想修改rfdig文件夹下的.c文件，参考rfdig_seca.cfg；执行：ccode_standard? ./rfdig? rfdig_seca.cfg ?>? 1.log
-
如图所示，脚本只替换了有关rfdig的寄存器，iomux，crg等没有替换：
-
- 如下例所示，脚本存放于case目录，我想修改rfdig/rfdig_tc017文件夹下的.c文件，参考所有rbus.cfg文件；
-
执行：ccode_standard ?./rfdig/rfdig_m33_tc017? all? > ?1.log
-
-
如图所示，脚本不仅替换了有关rfdig的寄存器，iomux，crg等都有替换：
