The following named cells represent the maximum available resources available for the considered device and package. None of these cells are visible in the spreadsheet, however you can use these read only values in your calculations.
| Resource | Named Cells | Description |
|---|---|---|
| LUTs | NUM_LUTS | Includes all LUTS |
| NUM_LUTRAM | Shift Registers and Distributed Memories LUTs | |
| Registers | NUM_FFS | |
| DSP blocks | NUM_DSPS | |
| Block RAMs | NUM_BRAMS | |
| PLLs | NUM_PLLS | |
| MMCMs | NUM_MMCMS | |
| DCMs | NUM_DCMS | |
| Transceivers | NUM_GTPS | Lowest speed blocks |
| NUM_GTS | Lower speed blocks | |
| NUM_GTHS | High Speed blocks | |
| NUM_GTZS | Highest Speed blocks |
- Examples
- Formulas to quickly set device utilization and evaluate thermal effects when
varying device, package or cooling parameters:
= INT(NUM_LUTS * 0.75) Sets total LUT utilization to 75% of device capacity (if entered on the Logic sheet)
= INT(NUM_DSPS * 0.90) Sets DSP block utilization to 90% of device capacity (if entered in DSP sheet)
