Antenna Error in Calibre DRC but Passed antenna check in Encounter

mingfatty
Dear Experts, I am using encounter to do my place and route after having obtain the macro lef from the abstract generator, everything's going fine until i stream out my gds2 file and check the DRC using Calibre in virtuoso, where i am getting hundreds of antenna error out of the antenna check. I wonder how could this happened and not reported in encounter. i am desperately need this to be solved and proceed to the tape-out. FYI, i am using IBM 130nm technology, and i am using the technology lef that provided by foundry (i wonder do i need to change any of my lef file to suit the Calibre check). Please kindly help! Thank you! Regards, MF
