WebFeb 15, 2005 · These timing exceptions have the ability to improve FPGA QoR by relaxing constraints on the timing paths of the design and potentially allow the FPGA to run faster. In this paper we have studied the impact of timing exceptions on nine designs using Synplify_pro from Synplicity for logic synthesis, Xilinx tools for place and route, and Focus … WebTiming Exceptions. A false path is a logic path in the design that exists but should not be analysed for timing. A false path is a point-to-point timing exception that removes all timing constraints from a path, which prevents errors from being reported but does not stop delay calculation. DC command used for setting a false path is set_false_path.
