Analog Rails To Release IC Design Environment August 31, 2008











Analog Rails Simulation Environment


Chandler, AZ (PRWEB) August 13, 2008

Analog Rails will release a IC Design environment on August 31, 2008. Analog Rails(TM) is a complete semi-automatic IC design environment targeting the entire analog circuit design flow. It is the most automated solution in the “custom” IC industry. Along with unified, correct by construction schematic and layout, Analog Rails features automatic layout, which includes an automatic placer, router, parameterized cells, and differential structures. Additionally, Analog Rails also incorporates a complete simulation environment. Layouts are assisted by real-time DRC and LVS aware functionality, which allows Analog Rails the unique approach of porting real parasitics. This enables the user to simulate with real layout values instead of estimations, which is the current industry standard. A free spice simulator is included so that the user can launch as many simulation runs as necessary for the built-in optimizer without requiring third party simulator licenses.

The release of this expert analog design system represents a new methodology based on inputs from leading designers in the industry. By simplifying analog design methodology via the combination of automated and semi-automatic approaches, Analog Rails addresses analog design challenges for next generation designs.

Steven Klass of Standard Microsystems had this to say in an article posted on his blog about Analog Rails: “This tool represents a clear methodology shift… The demise of the block level analog layout engineer. Why? First as I said earlier, the layout automation piece is very intuitive and friendly. Plus the smaller technology geometries that analog design is pushing into (less than 90nm) is forcing simulation earlier (using Cadence) to account for device parasitics (LOD). So the analog engineer is already doing a fair amount of the placement and letting the layout guy clean up the work. But this tool is correct by construction and so the layout is clean from the get-go. So involving a layout person to ‘clean it up’ isn’t necessary.”

Pirooz Hojabri, co-founder and VP of Engineering at Plato Networks, had this to say: “Utilizing the high ft of sub-micron CMOS has opened a new paradigm in circuit design and to reduce the product cycle time, there is a need to understand the parasitics early in development process. Analog Rails has taken a critical step in this direction.”

And Mike Kappes, CEO of IQanalog, said that “what Analog Rails is developing is a tool that will enable circuit designers to extend their deliverable from annotated schematics to finished and polished layout without outside layout or CAD involvement. Furthermore, having a tight coupling of schematics and layout design will result in better design practices with fewer extraction iterations.”

Analog Rails has been natively developed upon the new industry standard database, OpenAccess, which allows customers to seamlessly adopt individual tools or a whole flow. It also allows seamless design exchange between tools and partners supporting OpenAccess. OpenAccess has been widely accepted by leading EDA vendors such as Cadence, Synopsys, Mentor, Magma, and Silicon Canvas.

Free, 24/7 PDK support is included with every Analog Rails license purchase. Pricing, contacts, and specific details about Analog Rails (including online video demos), can be found at the company’s website, http://www.analograils.com.

Analog Devices Introduces Industry’s First Isolated Gate Drivers with Integrated Isolated Power: – ADuM5230 and ADuM6132 isolated half-bridge gate drivers reduce system cost and size while increasing quality and reliability for motor drives, power inverters, and plasma displays.

Saturday, March 5th, 2011



NORWOOD, Mass. (PRWEB) March 19, 2008

    Analog Devices’ engineers integrated an isolated power supply and isolated gate drivers in the same package by using the company’s award-winning iCoupler(R) technology. This provides isolated high-side and low-side outputs together with ADI’s proprietary isoPower(TM) integrated, isolated power. isoPower leverages iCoupler technology’s chip-scale micro-transformers along with high-voltage CMOS to create an isolated dc-to-dc converter.

About the ADuM5230 and ADuM6132 Isolated Half-Bridge Gate Drivers

The ADuM5230 and ADuM6132 are designed for implementations that include motor drives, plasma displays, and power inverters found in power supplies and solar power converters. On both devices, the integrated, isolated converter powers both the high-side output as well as any external buffer circuitry, eliminating the cost, space, and design complexity associated with external power supply configurations.

The ADuM5230 and ADuM6132 differ in power capability and high-side/low-side isolation configuration. In the ADuM5230, which supplies 150 mW of power, the high-side and low-side outputs are isolated from each other as well as from the inputs. In the ADuM6132, which supplies 250 mW of power, only the high-side output is isolated from the input.

In contrast to gate drivers employing high-voltage level translation methodologies, the ADuM5230 and ADuM6132 offer the benefit of true galvanic isolation between the inputs and outputs. On both products, the outputs may be operated up to +/-700 V (peak) relative to each other. On the ADuM5230, the isolated outputs may be operated up to +/-700 V (peak) relative to the inputs, thereby supporting low-side switching to negative voltages.

Availability and Pricing

The ADuM5230 will sample and be available in full production quantities in April 2008. Housed in a wide-body SOIC (small-outline integrated circuit) 16-lead package, the ADuM5230 is priced at $ 2.25 per unit in 1,000-unit quantities. For more information, visit http://www.analog.com/pr/ADuM5230.

The ADuM6132 is sampling now, and will be available in full production quantities in July 2008. Housed is a wide-body SOIC 16-lead package, the ADuM6132 is priced at $ 2.12 per unit in 1,000-unit quantities. For more information, visit http://www.analog.com/pr/ADuM6132.

A complete analog telephone interface

Wednesday, February 23rd, 2011

The ProSLIC® from Silicon Laboratories integrates a complete analog telephone interface into one low-voltage CMOS device and offers extensive software programmability to meet many global telephony requirements and customer specifications. In addition to performing all BORSCHT functions, the Si321x also dynamically generates and controls its own battery voltage, eliminating the need for external battery supplies. Two different battery generation architectures are supported: a BJT/inductor design offering a low-cost battery supply solution, and a MOSFET/transformer design offering increased power efficiency and a wider range of input voltages.

Si321x DC-DC Converter Description

The dc-dc converter dynamically generates the large negative voltages required to operate the linefeed interface. The Si321x acts as the controller for a buck-boost dc-dc converter that converts a positive dc voltage into the desired negative battery voltage. In addition to eliminating external power supplies, this allows the Si321x to minimize power dissipation by dynamically controlling the battery voltage to the minimum required for any given mode of operation.

Understanding the maximum power required by the ProSLIC linefeed circuitry to operate a worst-case specified load is the first step in determining the dc-dc converter design solution. Typically, the ringing state is the highest power consumption state for the SLIC, but in special cases the off-hook state can have the highest.

Undervoltage and Overcurrent Protection

The Si321x dc-dc converter is designed to operate under a specific input voltage and output loading condition. When the input voltage goes too low, there is not enough power from the input to deliver to the output; so, the dc-dc converter may try to draw excessive current in an attempt to deliver power to the output. A similar condition exists when the output ramps up too fast (during power up, transient loading), short loads, or unintentionally overloads the output. To prevent damage to the switching transistor during these abnormal conditions, the Si321x implements an undervoltage and overcurrent mechanism.

MOSFET/Transformer Design DC-DC Converter

The MOSFET/transformer dc-dc converter solution offers higher power efficiency than the BJT/inductor solutions and is the preferred solution for applications using low VDC input voltages.

Power Transformer

A transformer was designed for the Si321x dc-dc converter based on the TDK PC40EF12.6 E core. This transformer has three primary windings connected in series to handle all VDC voltage ranging from 3 V to 35 V (consult the factory for higher VDC). The secondary winding can generates up to 94.5 V VBAT at any in range VDC input.
