 In the early days of digital design, all circuits were designed manually. You would draw K-map, optimize the logic and draw the schematics. If you remember, we all did many logic optimization exercises back in college. It was time consuming and very error prone. This works fine for designs with a few hundred gates, but as the designs get larger and larger this became non-feasible.
Designs that are described at a higher level of abstraction are less prone to human errors. High-level descriptions of designs are done without significant concern regarding design constraints. The conversion from high-level descriptions to gates is done by using synthesis tools. These tools use various algorithms to optimize the design as a whole. This circumvents the problem with different designer styles for the different blocks in the design and sub-optimal design practices. Logic synthesis tools also allows for technology independent designs. Logic synthesis technology was commercialized around 2004, and since then it’s been part of the standard EDA tool chain for ASICs and FPGAs.

 Happy New Year!
January brought an unseasonably warm wave of weather to Las Vegas as International CES converged on the city this month.
The size and scope of this worldwide consumer electronics tradeshow continues to grow each year with new products and industries on the rise, now driven by a phenomenon called the “Internet of Things” (IoT).
Shawn Dubravac, Ph.D., Chief Economist and Director of Research for the Consumer Electronics Association (CEA) kicked off the event by presenting a summary of his new book, “Digital Destiny”.

 When I first launched Aldec in 1984, home computers hadn’t quite taken off and innovations such as the compact disk and those oversized, power draining cellphones were still struggling to obtain mass acceptance.
Fast forward 30 years, even those of us in the electronics industry have whiplash from the speed at which technology is advancing and delivering new products. Buyers are more eager to become early adopters of innovative new technology, and smarter, faster tools are required to keep pace.
As a long-time member of the Electronic Design Automation (EDA) community, Aldec has had a front row seat to the technology race and over the years we have celebrated many successes of our own. Here, our product managers reflect on some of our most memorable highlights from 2013.

 Here at the Aldec corporate office, we have a sign that reminds us all of our mission in the field of Technology. It reads, ‘To deliver solutions that provide the highest productivity to value ratio; supporting our existing products while delivering innovation to current and new technologies’. We have similar statements to reaffirm our commitment in the areas of Research, Alliances, and Culture – we call it our “Aldec DNA”.
 Because we genuinely want to have a clear understanding of our user’s requirements and methodology preferences, we continually engage in surveys and interviews. The knowledge we gain better positions us to support our existing products and to deliver that support where it matters the most to our users. If you’ve ever had that frustrating experience where your favorite tool no longer supports your methodology of choice – then you understand why this is so important.
Our Commitment to the VHDL Community
When it comes to VHDL-2008, we have learned from our customers that many are happy using the methodology – and continue to successfully deliver cutting-edge technology with it. So, while we remain committed to delivering innovation to new technologies, our R&D teams also invest a great deal of development time to ensure that Aldec solutions continue to offer a high level of support for popular languages like VHDL.

 As the proud Product Manager of Aldec’s FPGA Design Simulation solution, I am excited (like it was my first Cranberries concert) to announce that Active-HDL™ is celebrating 16 years since its initial release in 1997. Active-HDL has not merely stood the test of time, it has dominated the FPGA market like a Hulk Hogan smackdown with powerful simulation performance and debugging tools.
The key to Active-HDL’s long-term success lies in Aldec’s customer-centric philosophy. Simply put, we really do listen closely to our users and invest heavily in our tools. For this reason, continued simulation performance optimizations from release to release enable users to benefit from Active-HDL’s faster simulation even as the size of FPGA designs continues to grow.

 Retargeting Legacy Designs for New Technology
Digital design has come a long way since its inception from drawing schematic on paper, to CAD tools which can be used to draw schematics, and to today’s most popular (and efficient) process of describing designs through HDLs.
I recently encountered a customer with a legacy design developed in block diagram format. If he hadn’t been an Aldec customer, he might have been stuck. Fortunately, Aldec Active-HDL™ provides utilities for importing legacy schematic based designs from Xilinx® Foundation Series, ViewLogic™, ViewDraw™, Active-CAD™ or any schematic tools that can output an EDIF netlist.

 Productivity Boosting Features
Yes I did, but with no intention to start a holy war on which HDL editor is best. When it comes to HDL editors, each engineer has their own choice and I am not attempting to hurt any madly, deeply felt sentiments. My goal is only to bring the awareness to those using the HDL editor built into Active-HDL™ and to help them use it more efficiently.
There are two main categories for HDL editors (1) general purpose text editors, and (2) integrated text editors. Both have their own pros and cons, and in the end it is for each engineer to decide which suits their needs.
The HDL editor built into Active-HDL falls under the second category of integrated text editors. It offers many basic features (syntax highlighting, templates, columns selection, code folding, auto-formatting) as well as semantic features (code navigation, on-the-fly error detector), and also offers seamless integration with the simulator and version control system. The HDL editor in Active-HDL can be used with VHDL, Verilog, SystemVerilog, SystemC, C/C++, PSL, OVA, Perl scripts and Tcl scripts.
