Synopsys restarts some China services, sales of core tools still blocked, source says

Reuters3 days ago

BEIJING, June 12 (Reuters) - Synopsys (SNPS.O), opens new tab has resumed offering some services in China, relaxing a suspension it implemented earlier this month to comply with new U.S. export curbs, a source with direct knowledge of the matter told Reuters.
As tensions flared between the world's two largest economies last month, Washington ordered a broad range of companies to stop shipping goods to China.
The decision led Synopsys, a California-based provider of semiconductor design software, to halt sales and services in China and shut down access to its SolvNet customer support site.
Synopsys resumed some services last week, however, including sales of non-core hardware and intellectual property that allow it to serve some existing clients, said the source, who declined to be named as they were not permitted to speak to the media.
Synopsys did not immediately respond to a request for comment on Thursday.
SolvNet has also reopened with restrictions, including limits on access to some Electronic Design Automation software-related documents, the source added.
But sales of essential EDA tools remain suspended, meaning that Synopsys will still be unable to attract new customers as its intellectual property and hardware cannot be put to use, the source said.
The IP consists of code the company sells to users for chip design, while the hardware systems such as HAPS and ZeBu are part of Synopsys' hardware-assisted verification product portfolio, primarily used for verification of acceleration processes.
EDA software is used to compile IP and other designs onto hardware.
Synopsys, along with Cadence (CDNS.O), opens new tab and Siemens EDA (SIEGn.DE), opens new tab, dominates the EDA software chipmakers can use to design semiconductors for everything from smartphones to computers and cars. The three companies control more than 70% of China's EDA market, Chinese state news agency Xinhua reported in April.
Long-term restrictions on Chinese chip design companies' access to the tools would deal a significant blow to the industry in China.
Synopsys suspended its annual and quarterly forecasts after the U.S. implemented the restrictions, as they cast uncertainty over its ability to sell chip design software in China.

What is VTEC and Why Are Honda Fans Obsessed With It?

'VTEC just kicked in, yo!' is a popular phrase you've probably heard before, but there's a story and a meaning behind the saying. Part myth, part fact If you have driven or been around Honda-branded cars since the mid-1990s, you might be familiar with a four-letter word that has defined the brand's performance identity for decades: VTEC. Since its first automotive application in 1989, Honda's VTEC engine technology has given its four and six-cylinder engines a lot of lore and internet fame because of what it could do for spirited drivers and enthusiasts alike. But while there are many memes and misconceptions of what exactly happens under the hood, the tech behind VTEC has stood the test of time and is still used in Honda's new cars today. VTEC has its roots in these 90s automotive icons VTEC has been around longer than you think; it predates the Sega Game Gear, the Super Nintendo, and Dunkaroos. Initially introduced in 1989 in the Japanese-market version of the Honda Integra XSi, VTEC didn't make its way into the United States until the introduction of the Acura NSX supercar in 1991. The legendary mid-engined car's 3-liter C30A V6 engine produced just 270 horsepower. Still, the groundbreaking VTEC technology that gave the engine its unique performance characteristics would later be found in dozens of different Honda models, from humble commuters like the Civic and Accord to their high-performance Type-R versions. Honda VTEC engine In the early 1980s, Honda wanted to develop a new generation of engines for regular cars with a special touch that would further enhance performance. Variable valve timing, or VVT, had existed for some time before VTEC was developed, and automakers like Fiat and Alfa Romeo had used the technology in their own cars before Honda developed VTEC. But the Japanese automaker's lofty goals dictated its destiny. Honda management tasked its engineers with developing a naturally aspirated engine that would deliver 100 horsepower per liter of displacement—an impossible feat at the time. This meant developing an engine that could handle the load of higher speeds without sacrificing quality or reliability.

Its engineers tried everything, but one solution that did work was a system that could switch cam profiles on command: VTEC. VTEC stands for Variable Valve Timing & Lift Electronic Control System. While it may be an unusual name, it is derived from an engine technology that combines excellent fuel efficiency at low RPMs with a burst of power at high RPMs. This can be achieved by switching between two camshaft lobe profiles at different speeds within the rev range. VTEC in an engine VTEC in an engine All engines require air and fuel to turn over, and valves open up to allow air into a cylinder; a process controlled by cams on a camshaft and rocker arms. Each cylinder has cam followers with different cam profiles and rocker arms that can lock together. The taller cam lobes deliver VTEC power and connect to an inactive rocker arm. When activated, these lobes increase lift and extend lift duration, allowing more air to enter the engine at high RPM. When drivers mash the accelerator down, the engine speed rises, and so does the oil pressure. Once the engine reaches a certain RPM in Honda VTEC engines, the oil pressure pushes pins inside the rocker arms, locking them together. Since the rocker arms are locked together, all the intake valves (and exhaust valves, depending on the engine type) open wider, allowing more air in and creating more power. When the RPM drops, the oil pressure also drops, the locking pins go back to their original positions, and the lower-profile cams operate the valves back to the 'fuel economy' mode. 2000 Honda Civic Si Engine What are the performance benefits and downsides? The phrase 'VTEC just kicked in, yo!' is a term so ingrained in internet car enthusiast culture that it has its own page on Know Your Meme, but it is based on a real phenomenon that Honda drivers have experienced. In most other four-cylinder engines, the zone around the 5000-6000 RPM range is where most other cars would have their redline, as it would start losing power around this point. However, this traditional 'no-go zone' is where Honda's VTEC engines truly shine. Reaching the 'VTEC cutoff' can be characterized by a unique, brawny, high-revving sound and a sudden pull of instant power; a feeling that many late-model Civic and Accord drivers can attest to as addictive. As a whole, the VTEC system does what it was designed to do by Honda engineers and the managers who oversaw them; it delivers a lot of power in 1.6 to 2.4-liter inline four-cylinder or 3 to 3.5-liter V6 engines, solid fuel economy at the lower rev range, and virtually bulletproof reliability. In 2023, one 2003 Accord owner, Justin Kilmer, racked up one million miles on his V6 coupe through his work as a medical courier. But with its benefits, VTEC engines can suffer from feeling lethargic at lower speeds, as peak power and torque could be located ridiculously high on the rev counter. For instance, the 2.4-liter K24 DOHC VTEC engine in the 2006 Honda Civic Si produces 197 horsepower at 7,800 RPM, which is very close to its 8,000 RPM redline. 2000 Honda Civic Si Final thoughts Although VTEC has evolved over the years to include versions like i-VTEC, VTEC-E, and VTEC Turbo, 'copycats' of VTEC technology have been developed by other automakers, such as Toyota and Mitsubishi, while other automakers used other methods to achieve the same end goal. For example, the 996 Porsche 911 featured VarioCam, which used an adjustable chain tensioner to control the amount of slack in the timing chain that connects the intake and exhaust cams. BMW's VANOS on the M50 straight-six engine, used in cars like the E46 M3, employed a helical gear on the camshaft to adjust the timing. Today, many manufacturers, including American and European companies as well as several of Honda's competitors in Japan, employ some form of variable valve timing in their engines. However, VTEC remains a Honda hallmark as one of the first commercially successful variable valve timing technologies to be used in mass-produced cars, and a source of pride among Honda fans and owners.

UK ‘woefully' ill-protected against Chinese and Russian undersea cable sabotage

China and Russia are stepping up sabotage operations targeting undersea cables and the UK is unprepared to meet the mounting threat, according to new analysis. A report by the China Strategic Risks Institute (CSRI) analysed 12 incidents where national authorities had investigated alleged undersea cable sabotage between January 2021 and April 2025. Of the 10 cases in which a suspect vessel was identified, eight were directly linked to China or Russia through flag-state registration or company ownership. The involvement of 'shadow fleet' commercial vessels in these incidents is consistent with China and Russia's broader 'grey zone' strategy – a space between war and peace – which aims to coerce adversaries while minimising opportunities for response, the report claims. The patterns of activity – such as the involvement of Chinese vessels in suspicious incidents in the Baltic Sea, and Russian vessels near Taiwan – suggest possible coordination between Moscow and Beijing on undersea cable attacks, it said. It is estimated that up to 99% of intercontinental data transmission takes place through submarine cable systems, playing a vital role in civilian and defence infrastructure. Without undersea cables, much of the economy – from international banking and cloud computing to virtual communications and global logistics – would cease to function. The UK acts as a key hub in Euro-Atlantic cable infrastructure and is likely to become a frequent target for future sabotage operations. But a UK government submission to parliament's joint committee on the national security strategy admitted that it has limited capabilities to monitor commercial maritime traffic around undersea cables. The joint committee is mounting an investigation into the threat posed to the underseas cables and the possibility of more secure alternatives. The Department for Science, Innovation and Technology submission to the committee noted that 'the UK has limited capabilities for monitoring general maritime and white [commercial] shipping traffic, as coastal radar only covers about 22% of the exclusive economic zone (EEZ) around the UK. 'The high volume of maritime traffic makes it challenging to identify every instance of abnormal maritime activity. As a result, the current capabilities cannot fully guarantee that all vessels adhere to UK laws and regulations, especially around sensitive infrastructure like undersea cables.' Andrew Yeh, the executive director of CSRI and author of the report, said: 'Undersea cables underpin prosperity and security in the digital age. We cannot afford to be naive about the unprecedented threat that China and Russia's grey-zone operations pose to the UK's undersea infrastructure. 'While well set up to deal with conventional threats, the UK's defence infrastructure is woefully inadequate in protecting against grey-zone tactics. The UK must bolster its monitoring and surveillance capabilities, while looking to partners such as Taiwan who have a wealth of experience in countering grey-zone threats.' The recent strategic defence review admitted that underwater cables were becoming an increasingly vulnerable maritime domain. Sign up to This is Europe The most pressing stories and debates for Europeans – from identity to economics to the environment after newsletter promotion The UK is the landing point for 60 undersea cable systems, including nine out of the 15 undersea cables connecting North America to Europe. Only this month a Taiwanese court sentenced the Chinese captain of a ship to three years in jail after finding him guilty of intentionally damaging cables off the island in February. Proof of intent, as opposed to carelessness, is one of the difficulties in pursuing these cases in court. In the Taiwanese case, the Chinese captain said it was a case of negligence. Much of the law of the sea in relation to these highly sophisticated cables carrying hi-tech data is governed by the Cable Convention passed in 1884. Baltic Nato countries meeting in January vowed to boost patrol missions after several telecom and power cables were severed in the Baltic Sea in recent months, with experts and politicians accusing a Russian 'shadow fleet' of sabotage.

Mum killed in India crash was ‘reluctant to go' and feared leaving her son

A mother who died in the Air India plane crash had been reluctant to travel and feared leaving her young son behind for the first time, a colleague has said. Abdhiben Patel, known as Abdhi, 40, was killed when flight AI171 crashed shortly after take-off from Ahmedabad on Thursday. She had flown to India just two weeks earlier to care for her elderly mother, but was hesitant to make the trip and leave her eight-year-old son behind. 'She didn't want to go,' said Atif Karim, 45, her colleague and close friend at Zone Beauty Studio in Northampton. 'She told me, 'I just don't like being away from him'. It was her first time leaving him, and she was very nervous.' 'She wasn't excited,' he added. 'It was a sense of duty. Her mum was unwell, but you could tell it was weighing on her.' Mr Karim, a father of two, said recent tensions between India and Pakistan, which led to flight cancellations and uncertainty, had added to Mrs Patel's worries. 'All the flights were getting cancelled,' he said. 'It didn't feel like the right time.' Because her husband Pankaj worked night shifts, Mrs Patel was inseparable from their son Meer, he said. 'She kept saying how shy and reserved he is, how attached they were,' he added. 'She was totally devoted to him – her entire world revolved around him.' Mrs Patel had planned to return to work on Saturday. The day before the crash, she had messaged Mr Karim to check in about a task and offer to help finish it remotely. 'She said, 'Do you want me to finish that?' and later, 'Don't worry, I'll sort it,'' he said. 'That was the last I heard.' Originally from Gujarat, she moved to the UK in 2012 and joined the salon in 2016. She worked her way up over the years and had been managing the business for the last three. 'She was the most diligent, reliable worker I've ever had,' Mr Karim said. 'But more than that, she was our friend.' 'She was bubbly, kind, always smiling – she had a way of putting people at ease and always took a genuine interest in their lives.' 'She got on with everyone and left a real mark on the people she worked with and the customers she served. 'Yesterday, we had people coming in and crying their eyes out.' Inside the salon, he said the mood has changed, Mr Karim said. 'There's no music playing anymore,' he said. 'The staff are devastated. My colleague burst into tears when she walked in. 'Everyone's just heartbroken.' Mrs Patel's husband and son are now in India, where efforts are still ongoing to identify victims and return remains to grieving families. Authorities have since begun handing over remains after identifying some through DNA testing. The Boeing 787 Dreamliner had crashed into a residential area shortly after take-off, killing 241 people on board and at least 29 on the ground. Only one passenger – a 40-year-old British man – survived. A fundraiser has since been launched to support Mrs Patel's grieving husband and son, raising more than £4,000 in its first few days. The campaign is hoping to reach £50,000.
