Timing closure

Difference between Inverter and Buffer, when to use them during STA and Timing closure

In this blog post, we will discuss the difference between inverter and buffer, two common logic gates that are used in digital circuits. We will also explain when to use them for timing closure, a crucial step in the physical design of integrated circuits. ## What is an inverter? An inverter is a logic gate that produces an output that is the inverse of its input. For example, if the input is 1, the output is 0, and vice versa. An inverter can…

Tristate Buffers

You can think of tristate buffers as a way of turning a signal on and off. When the enable input at the top of the buffer is '1', the tristate buffer acts like a normal buffer. But when the enable input is '0', the buffer "turns off" by giving a very high impedance output. This effectively "disconnects" the buffer from the circuit. So if you need to turn off a signal, ground the enable input of the tristate bu…
