Development System Reference GuideChapter 15: SPEEDPRINT
Example Outputs
Following is the first part of a speed grade report for the XC4044XL device. The following command generates the displayed report.
speedprint xc4044xl
The default speed grade, temperature, and voltage settings are described at the beginning of the file.
Block delay report for a: x4044xl
Speed grade is: -09
Version id for speed file is: x1_0.45 1.24 PRELIMINARY xilinx
This speed file supports voltage adjustments over the range of 3.000000 to 3.600000 volts.
Temperature adjustments are supported over the junction temperature range of 0.000000 to 85.000000 degrees Celsius
This report prepared for default temperature and voltage.
Note - this report is intended to present the effect of different speedgrades and voltage/temperature adjustments on block delays, for specific situations use the timing analyzer report instead.
Delays are reported in picoseconds, where a range of delays is given they represent the fastest and slowest paths reported under that name.
When a block is placed in a site normally used for another type of block, a IOB placed in a Clock IOB site for example, small variations in delay may occur which are not included in this report.
