Pin mapping limit?

Hello

I try to make a design, which has a std_logic_vector(254 downto 0) as input.

A TCL script is used to assign the pins. This works well for the 100 first pins. Then they seam to be not recognized any more, even though they are shown in the Assignment Editor.

Is there a limit for vectors?

What could be the problem?
