A tristate buffer is a component in computer architectures that can either pass input to output when enabled or enter a high-impedance state (denoted by 'z') when disabled to prevent conflicts with other devices sharing the same data lines. ...
Warning: Tri-state node (s) do not directly drive top-level pin(s) è Warning: Converted the fan-out from the tri-state buffer “tribuf” to the node “comb” into an OR gate When I find the help message it state: --- Tri-state node(s) do not directly drive top-level p...
General Description Symbol Diagram The Tri-State Buffer (Bufoe) component is a non-inverting buffer with an active high output enable signal. When the output enable signal is true, the buffer functions as a standard buffer. When the output enable signal is false, the buffer turns off. ...
A CMOS tri-state buffer circuit transfers digital signals between a first digital circuit system operating at 3.3 Volts and a second system operating at 5 Volts. The buffer circuit receives an active high enable signal and a data signal as inputs to a tri-state select network. When the enabl...
the register outputs cannot be connected directly to the memory input/outputs, because when the memory is in the output condition, you will have memory outputs connected to register outputs, which is not tolerable. We need to use a three-state buffer to prevent the register outputs from collidi...
A tri-state output buffer has a signal input terminal, a control terminal and a signal ouput terminal and is controlled by a control signal applied to the control terminal so as to be selectively put
If I need to read the status of the pins into a register, which means I the tr-state output pins are connected to a reg variable (along with the output pins), I get the below mentioned warning from Quartus. Warning: Converted the fan-out from the tri-state buffer "i2c_expander_v...

According to your diagram clearly the bus_tri_d is not clock in the usual sense, neither is there any other register after it. so either timequest is going wrong or is misled or may be it has different rules for tristate buffer- just a guess. I can imagine that a...
