Inconsistent post-map Fmax

Hi

When I run a design through GUI, STA reported a Fmax of 680 MHz for a post-map netlist. When I ran the same design through command line, STA reported an Fmax of 86 MHz.

commands are:

quartus_map --64bit system_dp_256_script.qsf

quartus_sta --64bit system_dp_256_script --post_map --do_report_timing --sdc=system_dp_256_script.sdc

Post-map resources are same in the both the cases. If I try running STA on post-fit netlist, Fmax reported in the flows are consistent. Am I missing any arguments in command-line mode?

Regards
