What is standard cell in VLSI?
A standard cell is a group of transistor and interconnect structures that provides a boolean logic function (e.g., AND, OR, XOR, XNOR, inverters) or a storage function (flipflop or latch).
What is VLSI orientation?
Usually the orientation of a standard cell is in terms of mirror and rotation. Normal orientation would be no mirror and rotation of zero degrees. Other orientations are, for example: MX — mirrored about the X-axis. MY — mirrored about the Y-axis.
What do you mean by standard cells?
Definition of standard cell : a cell of known electromotive force used in the potentiometer calibration of electrical instruments.
What is a standard cell in chemistry?
Noun. 1. standard cell – a primary cell used as a standard of electromotive force. Clark cell, Clark standard cell – a form of voltaic cell once used as a standard for electromotive force.
What are the standard cell rows?
The height of this row is equal to the height of the standard cell. In digital designs most of the cases, the height of standard cells are constant and width varies. There may be double height cells , triple height cell, etc.
What are metal layers in VLSI?
What are Metal Layers? To route any PG/Clock/Signal we need metal layers. Metal layers connect the points of the two ends.
What is meant by metal stack in VLSI?
Cross-section diagram of a Metal Stack: This is basically a cross-section of different metal wire after the fabrication. In the sense, how different metals are placed and how they are connected.
What is APR in VLSI?
APR: Auto place and route is the process whereby a gate-level netlist (usually obtained from the synthesis tool) is physically implemented in layout by placing standard-cell layout and auto-routing the cells based on the connections inferred from the netlist.
What is standard potential of a cell?
A cell’s standard state potential is the potential of the cell under standard state conditions, which is approximated with concentrations of 1 mole per liter (1 M) and pressures of 1 atmosphere at 25oC. Write the oxidation and reduction half-reactions for the cell.
