An embodiment includes a tie-off circuit includes multiple field effect transistors (FETs), and a node isolation circuit that is connected to a first output node and a second output node of the tie-off circuit. The node isolation circuit consists of a first FET with a third output node and a second FET with a fourth output node. The second output node includes a logical LO node and is coupled to a gate of the first FET and generates a TIE HI output.

Node isolation for protection from electrostatic discharge (ESD) damage

A method and apparatus are provided for implementing an enhanced out of order processor instruction issue queue in a computer system. Instructions are selectively accepted into an instruction issue queue and ages are assigned to the accepted queue entry instructions using a queue counter. The queue entry instructions are issued based upon resources being ready and ages of the instructions. Ages of the queue entry instructions and the queue counter are selectively decremented, responsive to issuing instructions.

Implementing out of order processor instruction issue queue

Embodiments relate to electrostatic discharge (ESD) protection. One embodiment includes a tie-off circuit including a multiple field effect transistors (FETs), a first internal node, a second internal node, a first output node and a second output node. A node isolation circuit is connected to the first output node and the second output node of the tie-off circuit. The node isolation circuit includes a first FET with a third output node and a second FET with a fourth output node. The third output node and the fourth output node are electrically isolated from the first internal node and the second internal node.
