The sdf annotator is expecting to see the a simple continuous wire but raises an warning when it sees the short. Is there a way to prevent this warning from occurring either with the sdf generation step in Primetime or the SDF annotation step in VCS, or by any other means? Thanks SB ...

使用VCS读取SDF文件时,会将延迟值“反向标注(back-annotates)”到设计中,即在源文件中添加或者更改延迟值。 可以使用$sdf_annotate系统任务进行反标,其使用格式如下。 代码语言:javascript 复制 $sdf_annotate("sdf_file"[,module_instance][,"sdf_configfile"][,"sdf_logfile"][,"mtm_spec"][,"scale_factors...
