Although design houses have always strived for optimizing best design flows according to their design needs by customizing the flows using effective and efficient internal as well as external tools, this need has further grown in the context of design scenarios getting wider and wider from transistor, gate and RTL to system level.… Read More
Go ahead – type “open source” into the SemiWiki search box. Lots of recent articles on the IoT, not so many on EDA tools. Change takes a while. It has only been about five years since the Big Three plus Aldec sat down at the same table to work on UVM. Since then, Aldec has also gotten behind OS-VVM, and is now linked to a relatively new open… Read More
Usually these brief history pieces are totally written by the SemiWiki blogger whose name is at the top. Often me since that was how I prototyped book chapters (buy). Well, OK, I did actually write this but it is completely cribbed from a presentation earlier this week by Wally Rhines who gave a sort of keynote at the announcement of… Read More
A very popular acronym is ‘WYSIWYG’ – What You See Is What You Get! This is very true and is important to visualize things to make it better in various aspects such as aesthetics, compactness, organization, structure, understandable for correction and so on; the most important, in case of semiconductor design, is being able to identify… Read More
In the current decade of SoCs, semiconductor design size and complexity has grown by unprecedented scale in terms of gate density, number of IPs, memory blocks, analog and digital content and so on; and yet expected to increase further by many folds. Given that level of design, it’s imperative that SoC verification challenge has… Read More
In his DAC keynote last year (2012) Mike Mueller of ARM compared how much CPU was required to verify the first ARM versus one of the latest ARM Cortex CPUs. Of course the newer CPU is hundreds of times larger than the first ARM but the amount of verification required was millions of times as much, requiring ARM to construct their own datacenter… Read More
The Accellera Systems Initiative, most well-known for driving the standardization of various aspects of Verilog and SystemVerilog before handing the standards off to the IEEE, has announced that nominations are open for the 2013 Technical Excellence Award. This recognizes outstanding contributions in the creation of EDA… Read More
I speak VHDL and SystemC, others speak Verilog and SystemVerilog … what do you speak?
Before getting into the core of the topic let me give you some round figures, engineers love numbers. Julian Lonsdale “European Sales Manager at Aldec” informed me at the Xfest Munich last month that Aldec carried out a survey to evaluate the usage… Read More
Verilog History
Prabhu Goel founded Gateway Design Automation and Phil Moorby wrote the Verilog language back in 1984. In 1989 Cadence acquired Gateway and Verilog grew into a de-facto HDL standard. I first met Prabu at Wang Labs in 1982 where I designed a rather untestable custom chip named the WL-2001 (yes, it was named to honor… Read More
Intro
Mentor, Cadence and Synopsys all offer Verilog simulators, however when was the last time that you benchmarked your simulator against a tool from a smaller company?
I just heard from an RTL designer (who wants to remain anonymous) about his experience comparing a Verilog simulator called CVC from Tachyon against ModelSim… Read More
