When implementing a design in ISE 11.1, I receive the PAR Warning below.
However, I did not set the Placer Cost Table and do not see an option to change it in the PAR properties.
In ISE 11, the PAR cost table is not a visible property in Project Navigator.
As a result you cannot explicitly set it.
However, in order to ensure that the MAP and PAR cost tables match, Project Navigator is explicitly passing the par -t, with the same value that has been set in MAP.
If this was not done, and you had chosen a MAP cost table other than 1, PAR would post a warning indicating that the MAP and PAR cost tables do not match (because PAR uses a -1 as default when nothing is passed explicitly), and would let you know that it will use the MAP -t value instead of the [default] PAR -1 value.
In ISE 11.2, this deprecated message has been changed to an Informational message.
