I am facing problem in assigning pins as per useir defined location..
I am using some 56% only of the device logic and 68% pin usage.
The tool (ispLEVER) is automatically assigning the pins and Auto-fitting wise its not giving any problem. But when I am trying to assing pins as per my design, its shwoing errors... Even if I assign the same pin ( locking the pins) which tool already assigned ( so that it will nto change next time) then also its giving fitting error. How can it be possible ??
I am using ispLEVER version 4.2
Do anyone know whats the problem.. or which constraint setting can help me ?
