When floor planning (FP) and place & route (P&R) tools took over from custom layout tools for standard cell based designs, life became a lot better for designers of large digital chips. The beauty of the new flows was that all the internals of the standard cells and many IP blocks were hidden from view, lightening the load … Read More

On Tuesday Cadence made a big announcement about their new physical implementation offering, Innovus, during the keynote address at the CDNLive event in Silicon Valley. Cadence CEO Lip-Bu Tan alluded to it during his kick off talk, and next up Anirudh Devgan, Senior Vice President, Digital & Signoff Group, filled in more … Read More


FinFET & Multi-patterning Need Special P&R Handling

FinFET & Multi-patterning Need Special P&R Handling
by Pawan Fangaria on 04-28-2014 at 1:00 pm

I think by now a lot has been said about the necessity of multi-patterning at advanced technology nodes with extremely low feature size such as 20nm, because lithography using 193nm wavelength of light makes printing and manufacturing of semiconductor design very difficult. The multi-patterning is a novel semiconductor manufacturing… Read More


Expert Constraint Management Leads to Productivity & Faster Convergence

Expert Constraint Management Leads to Productivity & Faster Convergence

The SoC designs of today are much more complex than ever in terms of number of clocks, IPs, levels of hierarchies, several modes of operations, different types of validations and checks for growing number of constraints at various stages in the design flow. As a semiconductor design evolves through several stages from RTL to layout,… Read More


Macro Placement Challenges

Macro Placement Challenges
by Paul McLellan on 12-27-2013 at 7:28 pm

Image RemovedOne of the challenges of physical design of a modern SoC is that of macro placement. Back when a design just had a few macros then the flooplanning could be handled largely manually. But modern SoCs suffer from a number of problems. A new white paper from Mentor covers Olympus-SOCs features to address these issues:

  • As

Analog Constraint Standards

Analog Constraint Standards
by Paul McLellan on 09-20-2011 at 8:00 am

Image RemovedOver the years there has been a lot of standard creation in the IC design world to allow interoperability of tools from different vendors. One area of recent interest is interoperable constraints for custom IC design. Increasingly, analog design layout is becoming more automated. Advanced process nodes require… Read More
