Explore Your Interconnect the ICScape Way

Explore Your Interconnect the ICScape Way
by Paul McLellan on 09-09-2015 at 7:00 am

One of the surprises at DAC for ICScape was to be listed on Gary Smith’s list of companies to see. Surprised, since ICScape had never presented their products to him. They were listed under design debug. They don’t have a single product that really falls under that description, but rather a family of tools under the ICExplorer… Read More


How Good Is Your Library? Are You Sure?

How Good Is Your Library? Are You Sure?
by Paul McLellan on 05-26-2015 at 7:00 am

One task that is not very exciting but is critical is that of library quality assurance. Many design groups have created their own procedures, often having been burned in the past, to ensure that the libraries that they use are good. Failure to do so has resulted in:… Read More


How Good Are Your Clocks?

How Good Are Your Clocks?
by Paul McLellan on 04-29-2015 at 7:00 am

One of the trickiest tasks in designing a modern SoC is getting the clock tree(s) right. The two big reasons for this:

  • the clocks can consume 30% or more of the power of the whole chip, so minimizing the number of buffers inserted is critical to keeping power under control
  • the clock insertion delay and clock skew have a major impact on

What is Skipper?

What is Skipper?
by Paul McLellan on 04-01-2015 at 1:00 am

What is Skipper? Well, it seems it’s a penguin in the movie Madagascar. And one of Barbie’s sisters. Who knew? But for Semiwiki readers it’s an integrated chip finishing platform from ICScape. Skipper can read in full-chip layout extremely fast, examine it and manipulate it in various ways, and write it out again.… Read More


Efficient Handling of Timing ECOs

Efficient Handling of Timing ECOs
by Daniel Nenni on 05-29-2013 at 8:00 pm

Today, in the design of any type of system on chip (SoC), timing closure is a major problem and it only gets worse with each new, and more advanced process technology. Timing closure is closely inter-leaved with power and clock design. The complexity of achieving closure rises sharply with increasing design density and advancing… Read More


Interview with Jason Xing, Ph.D., CEO & President of ICScape Inc.

Interview with Jason Xing, Ph.D., CEO & President of ICScape Inc.
by Randy Smith on 05-19-2013 at 12:00 am

I recently had the opportunity to interview Jason Xing, Ph.D., CEO and President of ICScape, Inc. Below is a subset of the nearly two hour long interview.

How did you first become involved in EDA?
My EDA career started in the mid-90s when I started working on my PhD thesis at the University of Illinois in Urbana-Champaign. My thesis… Read More


Modern SoC designs require a placement- and routing-aware ECO solution to close timing

Modern SoC designs require a placement- and routing-aware ECO solution to close timing
by Jamie Chen on 05-09-2013 at 9:30 pm

As an applications engineer for over 15 years supporting physical design tools that enable implementation closure, I have seen the complexity of timing closure grow continuously from one process node to the next. At 28nm, the number of scenarios for timing sign-off has increased to the extent that is way beyond the number that … Read More


Properly Handing Of Clock Tree Synthesis Specifications

Properly Handing Of Clock Tree Synthesis Specifications
by Randy Smith on 04-28-2013 at 1:00 pm

Given today’s design requirements with respect to low power, there is increasing focus on the contribution to total power made by a design’s clock trees. The design decisions made by the front-end team to achieve high performance without wasting power must be conveyed to back-end team. This hand-off must be accurate… Read More


Current Timing Closure Techniques Can’t Scale – Requires New Solution

Current Timing Closure Techniques Can’t Scale – Requires New Solution
by Daniel Nenni on 10-16-2012 at 8:30 pm


There’s a nice article on timing closure by Dr. Jason Xing, Vice President of Engineering at ICScape Inc. on the Chip Design website. Not familiar with ICScape? Paul McLellan called ICScape the The Biggest EDA Company You’ve Never Heard Ofand Daniel Payne did Schematic, IC Layout, Clock and Timing Closure from ICScape atRead More
