DEF/LEF import issue on Windows install #1699

Closed aixalex closed 2 months ago

aixalex commented 2 months ago

Hi, I get a crash with Klayout 0.28.17 and 0.29.0 under Windows, when trying to import LEF/DEF. Same result when using KLayout in View mode or in Editor mode. Same result with 32bit or 64bit v0.29.0 installer This works fine with Klayout 0.27.11 under Linux. Reduced example DEF attached (toto.def.txt), file extension to be renamed as .def. No LEF file used. Import through GUI menus File>Import>DEF/LEF, all options left by default. Crash report below. Thanks for you help, Alex

Exception code: 0xc0000005 Program Version: KLayout 0.29.0 (2024-03-31 red486a687) x86

No tool should ever coredump. 'vim toto.def.txt' shows that your file has windows line endings.

I'm not sure whether it'll help you on Windows, but on linux/Mac you can use dos2unix or in vim ':set ff=unix' to change to unix line endings and klayout will read your file.

Since this def only contains DIEAREA you get away without reading lef (openroad requires lef), but for anything with NETS or COMPONENTS (with an orientation other then N), you will need lef with at least LAYER xxx WIDTH and MACRO definitions.

It does not coredump for me (Windows 10/64bit, version 0.29.0) ...

There is actually little that may go wrong here. Line endings should not matter.

@aixalex You can try the following:

  1. Clean you configuration (remove or rename c:\users\your_name\KLayout\klayoutrc). Maybe there is some setting, that KLayout can't digest (in that case, it would be interesting which one).
  2. Try "File/Open": The "Import" feature is deprecated and only left because it is the only way to import LEF. You can read DEF files directly from "File/Open".

Hi, Thanks for your advices. @stefanottili, I tried converting dos2unix, but even like that, klayout under Windows still crashes. Must be something else. @klayoutmatthias, I'm also under Windows 10, there must be something different on my machine.

  1. I removed klayoutrc file but this does not change anything. I did not find a way to activate log with verbosity to bring more information on the root cause, sorry.
  2. Effectively, with File>Open : then select my DEF file, this works fine.
  3. In my real case I need to import DEF and LEF (toto.def was a simplified testcase to show the issue). Thanks to your advices, I found the following workaround on Klayout under Windows :
    • File>Reader Options>LEF/DEF>Macro Layout Files : then select all my LEF files, all other left by default (in particular "Produce LEF geometry or use macro layout files for LEF FOREIGN")
    • File>Open : then select my DEF file, which will import successfully as the required MACRO LEF files are defined in the Reader Options. => Like this, no need to use the legacy File>Import menu any more

Thanks for your help, problem solved ;-) !
