Automatic Place and Route (APR) tools have been around since the 1980s for IC design teams to use, and before that routing was done manually by very patient layout designers. Initially the big IDMs had their own internal CAD groups coding APR tools in house, but eventually the commercial EDA market picked up this automation area,… Read More
DARPA Toolbox Initiative Boosts Design Productivity
When you think of the Defense Advanced Research Projects Agency (DARPA), this first thing that comes to mind is the development of the internet. And indeed, if you look at their website’s historic timeline, the development of ARPANET, as it was known at the time, is shown prominently in 1969. Incidentally, I actually used one of … Read More
Heterogeneous Package Design Challenges for ADAS
Increasingly complex heterogeneous packaging solutions have proved essential to meeting the rapidly scaling requirements for automotive electronics. Perhaps there is no better example of this than advanced driver-assistance systems (ADAS) that are found in most new cars. In a recent paper published by Siemens EDA, they … Read More
Electromigration and IR Drop Analysis has a New Entrant
My first IR drop analysis was back in the early 1980s at Intel, where I had to manually model the parasitics of the VDD and VSS interconnect for all of the IO cells that our team was designing in a graphics chip, then I ran that netlist in a SPICE simulator using transient analysis, measuring the bounce in VSS and droop in VDD levels as all… Read More
Formal Methods for Aircraft Standards Compliance
When promoting adoption of formal methods in functional verification, there are two hurdles to overcome: one technical, the other people. The first is a comfortable and familiar challenge for us engineers. Take the course, pass the test, get the certificate. Very mechanical and deterministic. People on the other hand are non-deterministic… Read More
Verifications Horizons 2021, Now More Siemens
In a discussion with Tom Fitzpatrick of Siemens EDA he recalled that their Verification Horizons newsletter started 17 years ago, back when they were Mentor. We’ve known about the Siemens acquisition for a while. The deal closed in March 2017, but it wasn’t until January 1, 2021 that the legal entity merger was complete. Which makes… Read More
Optimize AI Chips with Embedded Analytics
The foundry model, multi-source IP blocks, advanced packaging technologies, cloud computing, hyper-connectivity and access to open-source software have all contributed to the incredible electronics products of recent times. Along with this, the complexity of developing and taking a chip to market has also increased. And… Read More
AMS IC Designers need Full Tool Flows
Digital IC design gets a lot of attention, because all of our modern devices primarily use digital logic, but in reality whenever you have a sensor like a camera, accelerometer, gyroscope or any radio like Bluetooth, WiFi or NFC, then you’re really in the realm of analog, and that’s where mixed-signal IC design comes… Read More
Symmetry Requirements Becoming More Important and Challenging
Humans certainly have always had an aesthetic preference for symmetry. We also see symmetry showing up frequently in nature. The importance of symmetry in electronic designs has been apparent for decades. There are a host of analog structures that require balanced layout. For instance, these include differential pairs and … Read More
Debugging Embedded Software on Veloce
Arm provides great support for debugging embedded software in its CoreSight tools, but what support do you have if you’re debugging hardware and software together in a pre-implementation design? In a hardware debugger you have lots of support for hardware views like waveforms and register states. But these aren’t well connected… Read More
