Cadence Improves Virtuoso IC Design Platform

Cadence Design Systems has announced performance, capacity and usability enhancements to its Virtuoso IC design platform. The improvements in Virtuoso IC6.1.4 are said to reduce overall design time while ensuring quality production ICs. This is said to benefit design teams working along the full spectrum of design complexity, from the most advanced-node designs to more traditional chips. The Virtuoso release has been extended to work efficiently at advanced nodes down to 28nm and now supports 64-bit processing for improved capacity and performance.

The Virtuoso Space-Based Router has been integrated into the Virtuoso Layout Suite cockpit, making it easier to access. It now provides design teams a single common router they can use from start to finish to help ensure consistent results. Additional time-saving, quality-enhancing updates have been made to the Virtuoso Analog Design Environment XL, and Cadence design constraints technology. Integrating the Virtuoso Space-Based Router into the Virtuoso Layout Suite brings the power of a net-capable router to the desk of every layout engineer.

Interactive wire editing and full chip automatic finish routing share the same algorithms, providing a flow for a higher quality of design, from IP module creation though full chip sign-off. Improvements to the Virtuoso Analog Design Environment XL include display capabilities within the product that can now produce more and better datasheets. The Virtuoso Analog Design Environment's ability to analyse multiple tests simultaneously, including those across corner and statistical variations, helps engineers pick the best circuit design directions early on and verify those choices efficiently post implementation.

The Cadence design constraints methodology, which can help engineers reduce layout optimisation and design refinement times by as much as 20 per cent, received a boost in the new release, with enhancements that make it easier to add design constraints. In addition, there are new design constraints specifically geared to address sub-45nm design yield challenges. The release extends the Cadence ExpressPcells capability to support multiple-user sites.

Now customers can use their vast libraries of Skill-parameterised cells anywhere and see up to an eight times performance improvement. Cadence also improved the analogue display technology to handle multi-gigabyte waveform files more efficiently. The company has removed the two-gigabyte limit on waveform databases to account for today's larger, more complex designs. Performance has also been boosted for underlying design rule engines.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa...

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin...

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
