I have a proprietary PDK with a tech LEF containing a LEF58_WIDTHTABLE with a WRONGDIRECTION table. When I generate routing in OpenROAD it correctly uses the wider width for the non-pref dir. When we write the DEF we don't give any indication of the wrong way width as the DEF manual states that :
"The following LEF DRC rules allow a WRONGDIRECTION keyword that defines wrong-way widths that will affect the width of any wrong-way routes in the DEF NETS section: ... LEF58_WIDTHTABLE"
However when I look at the gds in KLayout I see it is min width in both directions. Does KLayout support this LEF constraint when converting DEF to GDS?
It would take some effort to build a dummy test case to illustrate the issue. Let me know if that is needed or not.
