tmax scanchain 删除多余管脚的问题

hegangben

各位大神，tmax 的 scanchain 有很多多余的管脚。我安装这个文件的说明 报了一层wrap

https://blog.csdn.net/lengxuemo/article/details/124302541

比如本来顶层是ipc
现在顶层是ipc_wrap，在ipc_wrap 例化了ipc，例化名为u_ipc，然后对多余的管脚做了处理。

$SYNOPSYS/auxx/syn/tmax/spfgen.pl 重新生成了spf，或者也采用自己写脚本手动删除了一些管脚信息（结果都一样）


read_drc  xxx.spf 出现 从20 个向量开始的


u_ipc 是新添加的层次，之前没有在和层次，scanchain 是带compressor 和 decompressor的。请问为啥会出现这种错误？该怎么设置？

或者一般scanchain 一般多余的关键的该怎么处理？

贴图，出错的信息

你懂程序吗

你这个过程看着没问题，你打开gui看看block 在哪了

非常感谢回复，是报的wrap 用assign 连线，可能是让工具识别以为插入了什么逻辑，现在是直接例化模块就那种方式连线就没有这种问题，但是现在的有出现了其他问题，在删除管脚的spf 中，没有报错误，但是向量跑不下去，感觉是spf

                               
登录/注册后可看大图

感觉是spf 整个初始值

在做管脚删除时没有设置好，但是现在不管怎么样整个值都不行。
