The following named cells represent operating limits for the considered device, package, speed grade and temperature grade. None of these cells are visible in the spreadsheet however you can use these read only values in your calculations.
| Resource | Named Cells | Description |
|---|---|---|
| Temperature | TJ_MAX | Maximum operating junction temperature (°C) |
| TJ_MIN | Minimum operating junction temperature (°C) | |
| Voltages | VCC_MAX | Maximum operating VCCINT voltage (V) |
| VCC_MIN | Minimum operating VCCINT voltage (V) | |
| Transceivers | GTP_MAXRATE | Maximum data rate of lowest speed blocks (Gb/s) |
| GTX_MAXRATE | Maximum data rate of lower speed blocks (Gb/s) | |
| GTH_MAXRATE | Maximum data rate of high speed blocks (Gb/s) | |
| GTZ_MAXRATE | Maximum data rate of highest speed blocks (Gb/s) |

Temperature cell on the Summary sheet to force the
device junction temperature to the maximum allowed while evaluating different
temperature or device and package combination:
= TJ_MAX
