DefineEndPoints

The DefineEndPoints command selects the starting and ending points of the paths that you want to analyze.

This command is equivalent to the Path Filters Custom Filters Select Sources and the Path Filters Custom Filters Select Destinations menu commands.

FPGA starting and ending points are: flip-flops, pads, nets, pins, CLBs, RAMs, latches, clocks, or timegroups. CPLD starting and ending points are: flip-flops, pads, nets, macrocells, or clocks.
