5.4.4.1. Optional Configuration Pins
Number | Done? | Checklist Item |
---|---|---|
1 | Plan the board design to support optional configuration pins as required. |
You can enable the following optional configuration pins:
- OSC_CLK_1—Must be connected to a 25 MHz, 100 MHz, or 125 MHz external source if EMIF and transceiver are used
- CONF_DONE
- INIT_DONE
- CVP_CONFDONE
- SEU_ERROR
- HPS_COLD_nRESET
- Direct to Factory Image
- nCATTRIP
nCATTRIP
The Catastrophic Trip (nCATTRIP) is an optional signal assignable to any unused SDM_IO pin. When enabled, the nCATTRIP signal de-asserts when core temperature is greater than the pre-defined temperature threshold value. You may assign your preferred temperature threshold value through the Device and Pin Options window of the Quartus® Prime software.
To enable the nCATTRIP output, select "USE nCATTRIP output" in the Configuration PIN GUI and assign the appropriate SDM I/O from the pulldown menu.
For more information about nCATTRIP and other optional configuration pins, refer to the Secure Device Manager (SDM) Optional Signal Pins section in Pin Connection Guidelines: Agilex™ 5 FPGAs and SoCs and the Power Management User Guide: Agilex™ 5 FPGAs and SoCs .
GUIDELINE: Ensure that you follow the pull-up recommendations for the nCATTRIP signal to avoid incorrect sampling before you configure your device.
nCATTRIP SDM_IO Assignment Options | Internal Pull-Up or Pull-Down | External Pull-Up Recommendation |
---|---|---|
1-7, 9-15 | 20kΩ pull-up | Not required |
0, 8, 16 | 20kΩ pull-down | Connect 4.7kΩ to VCCIO_SDM |
