WebA Time to Digital Converter core for Spartan 6 FPGAs. Web6 feb. 2024 · I have difficulties creating a TRI-STATE pin. The output logic should be: the pin is either pulled down to 0, or open-collector. I have a pull-up resistor between that pin and VCC (3.3 V). I'm expecting that if I write '0', it is low. When I write 'Z', it's open collector and pulled high by my pullup. But in my design, the pin stays low. 0.62 V.
