yes, you must make sure your pin assignment is ok before synthesis. you can use the auto-generated pin_assignment.tcl to configure the pin assignment, but do this first, you must read the tcl file and somtimes need modify it according to your project and memory requirement, for example 1.8V or 2.5V, ect.

Good luck!
