So I've built a custom FPGA development board that basically breaks out all the IO to headers, groups the power into 3 rails driven by an external bench supply and I've adjusted my J-tag wiring to ma...

Regular ContributorHello,
To make sure your power supply to FPGA meeting the FPGA requirements, could you please check below signals?
1- nCONFIG(active low) - turn low-then-high when FPGA completed power ramp up and start to enter configuration mode
2- nSTATUS(active low) - turn low-then-high when FPGA enters configuration mode.
3- CONF_DONE (active high)- turn high when FPGA completed configuration, and enter user mode.
If you dont see activity of above signals, the power supply is not meeting device requirements.
regards,
Farabi
