Australis eFPGA IP tool for rapid prototyping is built on OpenFPGA framework

Rapid prototyping of customisable FPGA architectures is automated with the latest tool from QuickLogic. The Australis embedded FPGA (eFPGA) IP Generator integrates QuickLogic’s best practices for performance, power, and area optimisation, said the company, to ensure low risk and low cost for eFPGA IP licensees

Its automation capability enables custom-parameterised eFPGA IP is available rapidly – within days in some cases, said the company.

Interest in domain-specific devices has been increased as the industry faces severe semiconductor supply constraints and difficulties keeping up with Moore’s Law, said QuickLogic. This is typically an expensive course for system developers and they may take longer to develop and may introduce risk. Integrating embedded FPGA technology can mitigate these risk but the fact that they are conventionally tied to a particular foundry and process node can deter developers. QuickLogic says Australis addresses these issues by giving developers the ability to customise eFPGA IP quickly and cost- effectively.

It is based on the OpenFPGA IP generator and adds additional features and capabilities specific to implementing QuickLogic’s eFPGA IP, along with testing and support required to build commercially-viable eFPGA IP.

It can provide ASIC/SoC developers a highly automated way to define and implement customised eFPGA IP. Embedded FPGA enables reprogrammable use, so that devices can address changing market conditions, support the evolution of new standards with the same silicon, customise implementations for IP protection, offload and accelerate hardware for artificial intelligence / machine learning  (AI / ML) or it can be used to create a range of product variants for small, niche or fragmented markets.

Australis provides customised eFPGA IP, from description to GDSII format in days and can meet specific Soc design requirements, such as being optimised for power, performance and area requirements.

According to QuickLogic, IP is a fraction of the cost of traditionally-built eFPGA IP cores.

In addition, a broad range of foundries and processes is supported, so developers can choose the best fab and technology for a given application.

ASIC / SoC and FPGA user tool support ensure seamless integration of the IP, continued QuickLogic.

The Australis eFPGA IP Generator is available now.

Renesas adds GUI and design parameters to Lab on the Cloud environment

Testing for voice and mobile applications are design parameters that Renesas Electronics has added to its Lab on the Cloud environment to simplify configuration and testing, while accelerating time to market.

The Lab on the Cloud environment enables customers to remotely access, configure, test, monitor and measure Renesas products instantly 24/7 in a cloud-connected lab. There, users can find evaluation boards for popular devices, together with proof of concept boards from Renesas and its partners. Users can access the physical lab through a PC-based graphics user interface (GUI) that enables them to immediately begin configuring and testing designs without requiring a physical board.

The GUI introduces parameters for control and additional results for monitoring. The ergonomic lab layout combined with an intuitive user interface have been designed to make it easier for users to quickly navigate the environment, said Renesas. For instance, the centralised live camera feed gives users a view of the complete lab set up and results; it also has the ability to zoom in and out on real time testing and data capture readings.

There are advanced implementations in test set ups and control for voice recognition, mobile application and power supply which enable users to complete complex testing such as transient performance in a few mouse clicks, Renesas continued.

New options include the Femtoclock2 point of use timing devices, which is claimed to be the smallest and lowest power clock generation and jitter attenuation device available, at less than 100fs.

Developers can test these and other devices via Lab On the Cloud to ensure stringent performance requirements are met, as well accelerating time to market.

New sections in the Lab on the Cloud suite including timing, power supply, voice recognition and control, healthcare, safety and surveillance, industrial communication, and IEEE 1588/5G computing and communication.

There are also a further 14 evaluation boards that have been added to the Lab on the Cloud environment, bringing the total to 23, covering IoT battery systems, industrial CAN sensor networks, voice recognition, air quality and capacitive liquid level indication, surveillance camera with CMOS sensor and a super capacitor-based terminal back up  power supply.

According to Renesas the enhancements of an advanced GUI and new design parameters create a more engaging and ergonomic user experience, and offer designers greater configuration flexibility.

Toshiba adds 20 microcontrollers to TXZ+ family for high speed data processing

Toshiba Electronics Europe has added 20 microcontrollers to its TXZ+ family. The M4G group microcontrollers use Arm Cortex-M4 microcontrollers for data processing and are manufactured using a 40nm process.

The microcontrollers, in common with existing TXZ+ devices can be used for high speed data processing applications, for example in IoT equipment, building automation, factory automation, home appliances, AV equipment, multi-function printers and other office equipment.

In addition to the Arm Cortex-M4 core, the new microcontrollers include a floating point unit (FPU) that runs at speeds up to 200MHz. They also integrate 2048kbyte of flash memory for code, a further 32kbyte of data flash with 100k write cycles endurance and 4kbyte of user data flash. They also incorporate multiple interfaces and various communication options.

As with the other devices in the M4G group, the latest additions have enhanced communication functions integrated as a serial memory interface. Among the standards supported are quad / octal SPI, audio interface (I2S), UART, FUART, TSPI and I2C. A three-unit DMAC and bus matrix structure is claimed to “significantly” improve communication throughput, compared to conventional products.

The new microcontrollers have a high speed, high precision 12-bit ADC to support a variety of sensing applications. The ADC allows individual sample-and-hold times to be set for each input channel with up to 24 channels. If integrated with Toshiba’s advanced programmable motor driver (A-PMD), the devices can also be used in AC motor, brushless DC (BLDC) motors, said the company.

Self-diagnosis functions for ROM, RAM, ADC and the clock contribute to the devices’ IEC60730 Class B functional safety certification. The microcontrollers maintain good compatibility with devices within the existing TXZ family M4G group.

Comprehensive documentation, sample software (with examples of actual usage), and driver software for each peripheral are available for free download on the company’s website. Additionally, evaluation boards and development environments are provided in co-operation with Toshiba’s global ecosystem partners.

The new microcontroller products are in mass production now.

Single axis MEMS capacitive accelerometers measure on three axes

Low noise, low cost MEMS capacitive accelerometer modules from Silicon Designs offer measurements on up to three orthogonal axes.

The Model 2210 series modules offer repeatable measurements across a variety of lower frequency vibration testing applications, including those common to vibration analysis, machinery control, modal analysis, robotics, and crash event detection, said Silicon Designs.

The modules are offered in standard ranges from ±2g to ±400g and incorporate a MEMS capacitive accelerometer chip together with high drive, low impedance buffering. They can be used in a Silicon Designs-recommended mounting block accessory, such as the Model 2330-BLK, to measure vibration and acceleration on either one, two, or three orthogonal axes with equal accuracy and repeatability. This degree of versatility in measurement allows customers to specify just one part number for multiple measurement requirements, reducing in-house costs and inventory counts.

All Silicon Designs’ Model 2210 series MEMS capacitive accelerometer modules generate two analogue voltage outputs which vary in response to applied acceleration. Customers can utilise either a single-ended or differential output. Using the latter doubles accelerometer sensitivity. The sensitive axis of the Model 2210 module is perpendicular to the package bottom, with positive acceleration defined as a force pushing on the bottom of that package. Output scale factor is independent from the supply voltage of +8.0 to +32V. At zero acceleration, differential output voltage is nominally 0V DC. At full scale, differential output is ±4V DC.

A simple, but robust, four-wire connection and internal voltage regulator minimise supply voltage variation effects. The MEMS capacitive sense element of each Model 2210 series accelerometer module is packaged within a lightweight, epoxy sealed and anodized aluminium housing which occupies a total footprint of one square inch (25mm), said Silicon Designs.

All Model 2210 series MEMS capacitive accelerometer modules are relatively insensitive to temperature changes and can self-calibrate.

Modules are designed, developed and manufactured at the company’s headquarters and ISO9001:2015 certified R&D centre, just outside of Seattle, Washington, USA. Each accelerometer also undergoes rigorous quality testing prior to shipment.
