I don't know if this is the exact place for this question. I have been using the write_sdf TCL command of PlanAhead for a while. After upgrading to ISE 14.4, the TCL console fails:
invalid command name "write_sdf"
The command appears in last valid version of the documentation (UG 789), and even the TCL help for some commands ("help write_verilog") refers to it ("See Also: write_sdf").
Could anyone from Xilinx confirm if this is a bug, the command has been renamed, or it has been removed.
