I use the LED’s on the unit to debug my programs. However, I found that under certain bit files, the LED is also quite dim.
My application requires the FPGA’s output to set the pins hi/lo on another device. This device’s pins are internally pulled high. When the FPGA led is dim, the FPGA cannot pull those down all the way either (although it does go part-way). Is this a defect with my FPGA?
What sort of bug in my verilog could cause such behavior?
