CDL: Circuit Description Language is a kind of netlist, a description of an electronic circuit. It is usually automatically generated from a circuit schematic. It is used for electronic circuit simulation and layout versus schematic (LVS) checks. It is similar to SPICE netlists, but with some extensions.

Schematic- driven layout allows for several features that make the layout designer's job easier and faster. One of the most important is that changes to the circuit schematic are easily translated to the layout. Another is that the connections between components in the schematic are graphically displayed in the layout ensuring work is correct by construction.

Vertical connections between these layers are often called vias. # Reduction: During reduction the software combines the extracted components into series and parallel combinations if possible and generates a netlist representation of the layout database. A similar reduction is performed on the "source" Schematic netlist. # Comparison: The extracted layout netlist is then compared to the netlist taken from the circuit schematic.

Figure 8: The AC input for an ASD. FIGURE 9: Single-Phase Half-Bridge Voltage Source Inverter The single-phase voltage source half-bridge inverters, are meant for lower voltage applications and are commonly used in power supplies. Figure 9 shows the circuit schematic of this inverter. Low-order current harmonics get injected back to the source voltage by the operation of the inverter.

As current in a wire or circuit element can flow in both directions, the direction representing positive current must be specified, usually by an arrow on the circuit schematic diagram. This is called the reference direction of the current. When analyzing electrical circuits, the actual direction of current through a specific circuit element is usually unknown until the analysis is completed. Consequently, the reference directions of currents are often assigned arbitrarily.

XCircuit is a Unix/X11 and Windows program for drawing publication-quality electrical circuit schematic diagrams and related figures and the production of circuit netlists through schematic capture. XCircuit regards circuits as inherently hierarchical and writes both PostScript output and hierarchical SPICE netlists. Circuit components are saved in and retrieved from libraries which are fully editable. XCircuit does not separate artistic expression from circuit drawing; it maintains flexibility in style without compromising the power of schematic capture.

Randles circuit schematic. A Randles circuit is an equivalent electrical circuit that consists of an active electrolyte resistance RS in series with the parallel combination of the double-layer capacitance Cdl and an impedance of a faradaic reaction. It is commonly used in Electrochemical impedance spectroscopy (EIS) for interpretation of impedance spectra, often with a Constant phase element (CPE) replacing the double layer capacity (Cdl). The Randles equivalent circuit is one of the simplest possible models describing processes at the electrochemical interface.

This architecture is referred to as folded because it takes its basis from the open array architecture from the perspective of the circuit schematic. The folded array architecture appears to remove DRAM cells in alternate pairs (because two DRAM cells share a single bitline contact) from a column, then move the DRAM cells from an adjacent column into the voids. The location where the bitline twists occupies additional area. To minimize area overhead, engineers select the simplest and most area-minimal twisting scheme that is able to reduce noise under the specified limit.

OrCAD Capture is a schematic capture application, and part of the OrCAD circuit design suite.OrCAD Capture, OrCAD Website Unlike NI Multisim, Capture does not contain in-built simulation features, but exports netlist data to the simulator, OrCAD EE. Capture can also export a hardware description of the circuit schematic to Verilog or VHDL, and netlists to circuit board designers such as OrCAD Layout, Allegro, and others. Capture includes a component information system (CIS), that links component package footprint data or simulation behavior data, with the circuit symbol in the schematic.OrCAD Features, OrCAD Website Capture includes a Tcl/Tk scripting functionality that allows users to write scripts, that allow customization and automation.

FIGURE 3: Single-Phase Voltage Source Full- Bridge Inverter FIGURE 4: Carrier and Modulating Signals for the Bipolar Pulsewidth Modulation Technique The full-bridge inverter is similar to the half bridge-inverter, but it has an additional leg to connect the neutral point to the load. Figure 3 shows the circuit schematic of the single-phase voltage source full-bridge inverter. To avoid shorting out the voltage source, S1+ and S1- cannot be on at the same time, and S2+ and S2- also cannot be on at the same time. Any modulating technique used for the full-bridge configuration should have either the top or the bottom switch of each leg on at any given time.
