Timing parameters and their representative values are selected for inclusion below either because they are important as general design requirements or they indicate fundamental device performance characteristics. The Spartan-3A DSP FPGA speed files (v1.29), part of the Xilinx Development Software, are the original source for many but not all of the values. The speed grade designations for these files are shown in Table 15. For more complete, more precise, and worst-case data, use the values reported by the Xilinx static timing analyzer (TRACE in the Xilinx development software) and back-annotated to the simulation netlist.
