WebUltimately you want to produce (either instantiate or infer) an IOBUF component or similar. This has one port IO that connects to the pin and three ports I, O and T that connect to your design in the fabric. Note that T is an active low enable. The OBUF (output buffer) part of the IOBUF will be enabled when T is low and tristate when T is high.

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.
