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
Digital IC design has been largely automated with high-level languages, RTL coding, logic synthesis, and automated place and route tools. What about analog IC layout automation, is it possible? A few EDA companies think that it is possible and even practical. In recent memory there were two companies really focused on analog … Read More
Timing closure is a “tortoise” for some system-on-chip (SoC) designers just the way many digital guys call RF design a “black art”. Chip designers often tell horror stories of doing up to 20 back-end physical synthesis place & route (SP&R) iterations with each iteration taking a week or more. “Timing closure”, a largely… Read More
Synopsys has been acquiring EDA and IP companies at a fast clip over the past few years and it’s often made me wonder how they are going to craft a coherent tool flow for custom IC design. At DACthis year I learned that for schematic capture the winning tool is Custom Designer SE– a relatively new tool, while the IC layout… Read More

Daniel Payne recently blogged some of the integration challenges facing Synopsys with their impending acquisition of SpringSoft. On my way back from San Diego last week I stopped by Tanner EDA to discuss an alternative tool flow for users who find themselves concerned about the Laker Custom Layout road map.
Design of the analog… Read More
Linda Fosler, Tom Daspit and Mitch from Mentor Graphics met with me last Monday at DAC to provide an update on IC layout and circuit simulation tools. My notes follow:
