Converting Synopsys SAED32nm EDK .tf file into .lef file

Hi,

I was wondering if anyone knows how to convert the Synopsys (Milkyway?) tech file (file extension .tf) into an LEF file that I can use for Cadence SoC Encounter.
The standard cell libraries that I am using have LEF files defined for them, but what I need is the technology LEF file.

I have tried using "generateLef" command in Encounter, but I get several parse errors when reading the file, and Encounter ultimately crashes.

Code:

generateLef -techFile /export/opt/synopsys/saed32/SAED32_EDK/tech/milkyway/saed32nm_1p9m_mw.tf saed.lef
dbgMicronPerDBU=0.001000
DATABASE MICRONS=1000, MIN GRID=1

Does anyone have experience with using this SAED32nm EDK library for Cadence Encounter or is there a way I can fix this error? I saw a similar thread from years ago that someone suggested to use the -clfFile option, but I do not have a Milkyway CLF file for this particular .tf file. Is there perhaps a Synopsys tool I can use to extract or generate a CLF file?

Any help at all would be greatly appreciated.

I can tell you the generateLef function inside Innovus is not for generating a tech lef. You can try using synopsys milkyway library management tool. It has a lot of conversion options

Thanks for the reply.
Is there a specific tool (i.e. program or terminal command) that runs this library management tool? I am googling for it but I cannot seem to find it anywhere.
