Tool suite eases the flow for utility meter design

Tue, Apr 27, 2021

Evaluation tools for ultrasonic flow converters by ScioSense give designers almost-instant measurement outputs to accelerate the design cycle for utility meters and other applications using AS6031 and AS6040 ultrasonic flow converters.

The ScioSense tool suite for the AS6031 and AS6040 ultrasonic flow sensors includes dedicated development boards and new evaluation software.

The AS6031 and the AS6040 UFCs provide precise measurements of time of flight that convert into flow rate of gas or water.

The development tools include general-purpose or microcontroller-specific boards, and evaluation software which provides an intuitive graphics user interface (GUI) for sensor configuration and for the display of measurement outputs.

The UFC evaluation software provides a framework for configuring transducer and spool piece settings, enabling developers to start acquiring flow rate data from the sensors quickly after powering up the sensor board. The software displays the measurement results in either a graphical or numerical format.

Developers can also choose to use a wizard to guide them through the settings. Data can be exported for subsequent data analysis in other tools.

The evaluation software is supplied free with any of the evaluation boards for the AS6031 and AS6040.

Stand-alone evaluation kits, the AS6031-QF_DK and AS6040-QF_DK, include a PICOPROG USB programming interface and cables. ScioSense also supplies Nucleo shields (or demo boards) which are compatible with any STMicroelectronics STM32 microcontroller family. The AS6031-QF_NUC and AS6040-QF_NUC boards are supplied with sample code for communication with STM32 microcontrollers, including libraries for configuration download, initialisation and data readout.

The combination of evaluation boards and evaluation software provide a convenient platform for users to integrate an AS6031 or AS6040 ultrasonic flow sensor instantly into the measurement set-up. Instead of spending time on basic system configuration, they can focus on characterising the operation of the application over the range of flow rates and ambient temperatures, says the company.

The AS6040 and AS6031 ultrasonic flow converters with integrated 32-bit CPU core include all the functions required to drive a pair of external transducers, and to convert ultrasonic time of flight measurements to a calculation of the rate of flow. The sensors are notable for their low power consumption, high accuracy, and high sensitivity.

The AS6031 and AS6040 evaluation kits are available for purchase directly from ScioSense or from authorised distributors.

White chip LEDs save space in IoT devices and drones

Fri, Apr 23, 2021

Compact high luminous intensity white chip LEDs from Rohm are optimised for applications which require high brightness white light emission. The CSL1104WB LEDs are intended for IoT devices, drones, and other battery equipped applications.

High luminous intensity (2.0cd) white LEDs are being increasingly adopted to improve visibility in a range of applications in the consumer electronics and automotive sectors. At the same time, the emergence of applications that mount multiple LEDs in a small space – for example IoT devices and drones – require high density mounting. This makes it difficult to achieve high brightness in a compact footprint, explains Rohm.

The CSL1104WB series achieves a high luminous intensity of 2.0cd in an ultra-compact 1608 size (1.6 x 0.8mm for 1.28mm²), which was previously difficult to achieve. The result is the same luminosity as the current mainstream 3528 size PLCC package (3.5 x 2.8mm or 9.8mm²) but in an 87 per cent smaller form factor.

Colour variation is significantly improved, simplifying the colour adjustment process by ensuring accurate white colour chromaticity, says Rohm. This contributes to space savings, but also improves design flexibility along with visibility through high density mounting of high luminosity LEDs. Qualification under the automotive reliability standard AEC-Q102 is specifically developed for optical devices is planned, enabling a smooth application inside industrial equipment and automotive applications that are exposed to harsh environments.

Rohm is committed to expand its line up of 1608 size white chip LEDs from low to high brightness.

Rohm Semiconductor develops and manufactures a large product range from SiC diodes and MOSFETs, analogue ICs such as gate drivers and power management ICs to power transistors and diodes to passive components. The company has manufacturing plants in Japan, Korea, Malaysia, Thailand, the Philippines, and China.

Lapis Technology and Lapis Semiconductor (former OKI Semiconductor), SiCrystal and Kionix are companies of the Rohm Semiconductor Group. Rohm Semiconductor Europe has its head office near Dusseldorf, Germany serving the EMEA region (Europe, Middle East and Africa).

Fri, Apr 23, 2021

Smart luminaires for indoor and outdoor installations have been introduced by Ledvance. The Smart+ range can be controlled via remote, app or voice. The range includes panel and flood luminaires, a neon flex strip and camera functions.

The wall and ceiling assortment includes round luminaires in a decorative design as well as sleek and timeless panel luminaires. For outdoor installations, Ledvance offers products for mood, decorative lighting and security purposes. The Neon Flex TGBW LED strips are designed for indoors and outdoors and offer a smooth and seamless illumination with RGB and tuneable white option. All new smart luminaires are easily and quickly installed and are available now, says Ledvance.

The Smart+ Wi-Fi Planon are smart panel luminaires that will slot seamlessly into any indoor installation. The Smart+ Planon comes in three different form factors including square versions measuring 300, 400 or 600mm (20W/ 28W/ 40W) in length, frameless rectangular option in six sizes (20W/ 28W/ 35W/ 40W) or as frameless round luminaires with two diameters (20W/ 28W). All Smart+ WIFI Planon models feature tuneable white and some also RGB functions, and can be connected via Wi-Fi. Using the Ledvance Wi-Fi app or a speaker device, users can control the luminaire and timer or select dynamic lighting options by switching from warm to cool light with tuneable white.

The slim, lightweight, robust and durable Smart+ Wi-Fi flood luminaires are for garden illuminations. The luminaire’s tempered glass cover with semi-frosted finish allows for a very homogenous illumination and the smart and intelligent control options enable both general lighting as well as mood lighting. The luminaires can be controlled by app or a voice controlled speaker device within the local Wi-Fi, to change colours, dim the light or to switch it on/off. The IP65 certified luminaries are available in four versions (10W/ 20W/ 30W/ 50W).

Synopsys bundles design engines for hyper-convergent ICs

Fri, Apr 23, 2021

For memory, artificial intelligence (AI), automotive and 5G applications, the PrimeSim design environment provides comprehensive analysis, improved productivity, says Synopsys.

At the SNUG World international user conference, Synopsys unveiled the PrimeSim Continuum. This is a unified workflow for circuit simulation technologies to accelerate the creation and signoff of hyper-convergent designs. PrimeSim Continuum is built on next-generation Spice and FastSpice architectures and is the industry’s only proven GPU acceleration technology, claims Synopsys. It provides design teams 10X runtime improvements with golden signoff accuracy, says the company. PrimeSim Continuum combines PrimeSim Spice, PrimeSim Pro, PrimeSim HSpice and PrimeSim XA. PrimeWave delivers a seamless simulation experience around all PrimeSim engines with comprehensive analysis, improved productivity and ease of use.

“PrimeSim Continuum represents a revolutionary breakthrough in circuit simulation innovation with heterogeneous compute acceleration on GPU/CPU, setting a new bar for EDA solutions,” said Sassine Ghazi, chief operating officer (COO) at Synopsys. The PrimeSim Continuum technologies complement the company’s Custom Design Platform and Verification Continuum, continued Ghazi.

Today’s hyper-convergent SoCs consist of larger and faster embedded memories, analogue front-end devices and complex I/O circuits that communicate at 100Gb+ data rates with the DRAM stack connected on the same piece of silicon in a system-in-package (SiP) design. Verifying complex designs at advanced technology process nodes present increased parasitics, process variability and reduced margins, reports Synopsys. This results in more simulations with longer runtimes at higher accuracy impacting the overall time-to-results, quality-of-results and cost-of-results. PrimeSim Continuum addresses the systemic complexity of such hyper-convergent designs with a unified workflow of sign-off quality simulation engines tuned for analogue, mixed-signal, RF, custom digital memory designs, says Synopsys. PrimeSim Continuum uses next-generation Spice and FastSpice architectures and heterogenous computing to optimise the use of CPU and GPU resources and improve time-to-results and cost of results.

The PrimeSim Pro simulator represents a next-generation FastSpice architecture for fast and high-capacity analysis of modern DRAM and Fflash memory designs.

The PrimeSim Spice simulator’s next-generation architecture with GPU technology delivers significant performance improvements needed to perform comprehensive analysis for analogue and RF design while meeting signoff accuracy requirements.

The PrimeSim Continuum integrates PrimeSim Spice and PrimeSim Pro with the PrimeSim HSpice simulator for foundation IP and signal integrity and the PrimeSim XA simulator, for SRAM and mixed-signal verification. PrimeWave delivers a seamless experience by providing a consistent and flexible environment across all PrimeSim Continuum engines optimising design set-up, analysis and post-processing, says Synopsys.

PrimeSim Continuum is available now.
