If, like me, you’ve been paying too little attention to historically less glamorous areas of chip design like packaging, you’ll wake up one day and realize just how much things have changed and continue to advance and how interesting it’s become.
One of the main drivers here is the increasing use of chiplets to counter the decreasing… Read More
On big chip design projects the logic verification effort can be larger than the design effort, taking up to 70% of the project time based on data from the 2022 Wilson Research Group findings. Sadly, the first silicon success rate has gone downwards from 31 percent to just 24 percent in the past 8 years, causing another spin to correct… Read More
This. AI in PCB design is not a new idea. Other PCB software companies also make that claim. But when a mainstream systems technology company like Siemens talks about the subject, that is noteworthy. They already have an adaptive user interface (UI) for their mechanical modeling suite and to assist in low-code development for application… Read More
You don’t often hear about the inner workings of EDA tools and flows – the marketing guys much prefer telling us about all the exciting things their tools can do rather than the internal plumbing. But this matters for making design flows – and building these has largely been left to the users to sort out. That’s an increasing challenge… Read More
I first heard about High Level Synthesis (HLS) while working in EDA at Viewlogic back in the 1990s, and have kept watch on the trends over the past decades. Earlier this year Siemens EDA hosted a two day event, having speakers from well-known companies share their experiences about using HLS and High Level Verification (HLV) in their… Read More
SemiWiki readers from a digital IC background might find it surprising that post-PCB route analysis for high speed serial links isn’t a routine and fully automated part of the board design process. For us, the difference between pre- and post-route verification is running a slightly more accurate extraction and adding SI modelling,… Read More
The last thing you want when taping out a design is to hit large numbers of violations in signoff checks that could have been flushed out and resolved in earlier flow iterations. For implementation flows (floorplanning, synthesis, place and route), it’s usual to do a lot of flow flushing work early in the design cycle and iteratively… Read More
Before chiplets arrived, it seemed like designing an electronic system was a bit simpler, as a system on chip (SoC) methodology was well understood, and each SoC was mounted inside a package, then the packages for each component were interconnected on a printed circuit board (PCB). The emerging trend to design a 3D IC using chiplets… Read More
As more AI applications turn to edge computing to reduce latencies, the need for more computational performance at the edge continues to increase. However, commodity compute engines don’t have enough compute power or are too power-hungry to meet the needs of edge systems. Thus, when designing AI accelerators for the edge, Joe… Read More
My IC design career started just a few years before PADS got started in 1985 with a DOS-based tool for PCB design. A lot has changed since then, as PADS was acquired by Mentor Graphics in 2001, and continued to grow under Siemens EDA, now with four versions to choose from, where the top version is called PADS Professional Premium:
