An Encounter error of supporting POLYGON with 45 degree edges

Hi all,

I got a lot of errors when reading Bond pad Lef information in Encounter. It happened during special routing.All these errors are relative to supporting POLYGON with 45 degree edges. I am using Encounter 7.1.

Reading LEF technology info...

*ERROR* "/home/cadence/TSMC/IO_lib/tpbn90nv_130a/tpbn90nv_130a_sefp9/TSMCHOME/digital/Back_End/lef/tpbn90nv_130a/cup/9lm/9M_6X2Y/lef/tpbn90nv_9lm.lef", line 59: VERSION must be 5.6 or higher to support POLYGON with 45 degree edges at or near "4.780"

In bond pad lef file, line 59:

POLYGON 53.000 70.220 51.220 72.000 51.220 3.000 53.000 4.780 ;

Ang help. Thanks in advanced

Hi,
Change the VERSION statement in the top of the LEF file to be 5.6 and see if it reads in cleanly.
