GDS Stream in遇到的问题

mycoal

各位大佬，业余人员在此求助关于Virtuoso Stream in GDS的问题：

1. 环境：虚拟机IC618_rf
2. GDS：由Gerber文件通过Klayout转换而来。
3. 目的：已有某Fab的PDK文件，希望对GDS文件进行DRC。
4. Stream in 设置：如图所示。
5. 问题：Translate时报错如下：
ERROR (XSTRM-166): Translation Failed - Parser: The 'XY' parameter of the 'BOUNDARY' record in the GDSII file '/home/IC/GDS/TV9-2_0-20250922-V0.GDS' contains an insufficient number of points '0' near the offset '2439398'. Expected at least '2' points.

对此问题一无所知一头雾水，请大佬救我~~~

It seems that it is not legal GDS.
A PATH object is defined as a shape with 2 or more vertices and a width and endtype parameters.
In this case there is only one vertex defined. To create a path correctly, the Cadence layout tools need 2 points.
gds generated by the Klayout is representing something that is not representing real layout (I.D markers?, dots?)
There are various options to ignore bad data, but I think you may need to make sure that the original GDS has clean data before importing

但是同样的GDS文件在RHEL6_IC617里面是可以顺利导入的，只不过DRC版本不支持（要求calibre version 2018.4_51.44，实际 version 2015.2_36.27），还是跑不了。

Tech File 和上面的Tech Library填一个就可以了吧？试过两个都填上了，问题还是有的。

可以尝试一下，把你的GDS里面的"-"改成"_",是不是非法字符引起的。另外可以看看你的版图里面是不是有一些别的不相关的layer
