PIN2UCF Scenarios
R
UCF is present.
The UCF contains some
user-specified pin-locking
constraints either inside or
outside of the PINLOCK
section.
Some of the user-specified
constraints conflict with the
PIN2UCF generated
constraints
PIN2UCF does not write the
PINLOCK section. Instead, it exits
after providing an error message. It
writes a list of conflicting
constraints.

UCF is present.
There are no pin-locking
constraints in the UCF.
There is a PINLOCK section
in the UCF generated from a
previous run of PIN2UCF or
manually created by the
user.
None of the constraints in the
PINLOCK section conflict
with PIN2UCF generated
constraints.
PIN2UCF writes a new PINLOCK
section in the UCF after deleting the
existing PINLOCK section. The
contents of the existing PINLOCK
section are moved to the new
PINLOCK section.
