Designing the Right Architecture Using HLS

Designing the Right Architecture Using HLS
by Pawan Fangaria on 09-17-2014 at 9:05 am

With the advent of HLS tools, general notion which comes to mind is that okay, there’s an automated tool which can optimize your design description written in C++/SystemC and provide you a perfect RTL. In real life, it’s not so, any design description needs hardware designer’s expertise to adopt right algorithm and architecture… Read More


International Workshop on Logic and Synthesis

International Workshop on Logic and Synthesis
by Paul McLellan on 04-20-2014 at 12:54 am

There are always a number of other events that are colocated with DAC. One this year is the 23rd International Workshop on Logic and Synthesis (IWLS) that is held the weekend before DAC on May 30th and June 1st. Strictly speaking it is not colocated since it is in the Galleria Park Hotel on Sutter Street a few blocks away whereas DAC itself… Read More


Top 10 Reasons to Use Vivado Design Suite

Top 10 Reasons to Use Vivado Design Suite
by Paul McLellan on 03-23-2014 at 7:05 am

Here are the top 10 reasons to use the Xilinx Vivado Design Suite to design your All Programmable Devices:

Reason number 10: Accelerate verification by over 100XThe Vivado Design Suite System Edition lets you do design at the C, C++ or systemC level. But a side-benefit is that you can use these languages for verification at performances… 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


Don’t Shoot Yourself in the Foot With Timing Exceptions

Don’t Shoot Yourself in the Foot With Timing Exceptions
by Paul McLellan on 08-15-2013 at 1:42 pm

Timing exceptions are ways of guiding design tools, primarily synthesis and static timing analysis (STA), but these days also place & route and perhaps other tools. Most paths in a design go from one register to the next register. Both registers are on the same clock, and the design needs to ensure that the signal can make it from… Read More


New Book on Design Constraints

New Book on Design Constraints
by Paul McLellan on 07-20-2013 at 10:18 pm

There is a new book out from Springer. The subtitle is actually a better description that the title. The subtitle is A Practical Guide to Synopsys Design Constraints (SDC) but the title isConstraining Designs for Synthesis and Timing Analysis. The authors are Sridhar Gangadharan of Atrenta in San Jose and Sanjay Churiwala of Xilinx… Read More


Easy SystemC Debugging

Easy SystemC Debugging
by Randy Smith on 07-03-2013 at 7:00 pm

Electronic system design has been slowly migrating to higher level languages such as SystemC for more than a decade now. SystemC is an open source C++ library that has emerged as a standard for high-level design and system modeling. Writing code in SystemC has several advantages which I won’t elaborate on in this article, though… Read More


Interview with Forte CTO John Sanguinetti on Cynthesizer 5

Interview with Forte CTO John Sanguinetti on Cynthesizer 5
by Randy Smith on 05-26-2013 at 12:00 pm

Recently, Forte Design Systems announced the release of a new core engine to their popular high-level synthesis tool offering. It is a large undertaking, so I asked John Sanguinetti, Forte’s CTO, to answer some questions about that development effort.

Q. How long has it been since the last major upgrade of the CynthesizerRead 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
