Decisive Floorplanning for Faster Design Closure

Decisive Floorplanning for Faster Design Closure
by Pawan Fangaria on 01-18-2016 at 4:00 pm

Semiconductor design automation at system level is gaining its due importance today. It needs an effective, efficient, and seamless flow from system up to silicon. There is lot of effort going on for automating SoC design exploration at system level but that eventually stops at RTL; another level of flow automation takes over … Read More


Automating Timing Closure Using Interconnect IP, Physical Information

Automating Timing Closure Using Interconnect IP, Physical Information
by Majeed Ahmad on 04-29-2015 at 1:00 pm

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

The over 20 years of experience behind Synopsys Design Compiler is getting a new look for 2014, and we had a few minutes with Priti Vijayvargiya, director of product marketing for RTL synthesis, to explore what’s in the latest version of the synthesis tool.

Previewed today, Synopsys Design Compiler 2013.12 continues to target … Read More


Mentor Buys Oasys

Mentor Buys Oasys
by Paul McLellan on 12-14-2013 at 1:24 pm

Mentor is acquiring Oasys, subject to all the usual caveats about shareholder and regulatory approval. The shareholder paperwork went out earlier this week. The common stock is valueless so presumably the price is low (and Mentor historically has not paid high prices for its acquisitions).

So what is going to happen with the technology?… Read More


Floorplanning Merged With Synthesis

Floorplanning Merged With Synthesis
by Paul McLellan on 10-02-2013 at 2:45 pm

One area of iteration that is becoming more problematic is between floorplanning and synthesis. So much of timing is driven by placement that fixing timing and even power often involves not just re-synthesis and re-placement but alterations to the floorplan. The Achilles heel of existing methods is that floorplanning tools … Read More


Oasys Announces Floorplan Compiler

Oasys Announces Floorplan Compiler
by Paul McLellan on 05-19-2013 at 5:58 pm

Today Oasys announced the availability of Floorplan Compiler in the Oasys RealTime suite of physical RTL exploration and synthesis tools. This is actually a repackaging of a capability that has always been in RealTime Designer, and in fact has been an important aspect of how well RealTime Designer has performed in benchmarks … Read More


How to use NoC to avoid routing congestion

How to use NoC to avoid routing congestion
by Eric Esteve on 11-23-2011 at 5:21 am

Network-on-Chip (NoC) is an emerging paradigm for communications within large VLSI systems implemented on a single silicon chip. Sgroi et al. call “the layered-stack approach to the design of the on-chip intercore communications the Network-on-Chip (NOC) methodology.” In a NoC system, modules such as processorRead More
