As a 30+ year semiconductor veteran I can tell you with 100% certainty that start-ups are the lifeblood of EDA. The mantra is “Innovate or Die!” and that is exactly what Defacto is doing. After more than 10 years of innovating in Design for Test at RTL, Defacto is now offering a complete EDA solution based on generic EDA… Read More

DFT Approaches for Giga-gate SoC Designs
In the early days of IC design there were arguments against using any extra transistors or gates for testability purposes, because that would be adding extra silicon area which in turn would drive up the costs of the chip and product. Today we are older and wiser, realizing that there are product pricing benefits to quickly test each… Read More
A Brief History of Defacto Technologies
In early 2000s, semiconductor design at RTL level was gaining momentum. The idea was to process more design steps such as insertion of test and other design structures upfront at the RTL level. The design optimization and verification were to be done at the RTL level to reduce long iterations through gate level design because changes… Read More
HW Emulator Apps Open Doors to Entirely New Uses
When the topic of hardware emulation comes up, thoughts of big iron customarily come to mind. However, hardware emulation has evolved significantly and now there are other important traits that distinguish the offerings in this area. For a very long period of time emulators provided primarily a method to accelerate gate level… Read More
Cadence Adds New Dimension to SoC Test Solution
It requires lateral thinking in bringing new innovation into conventional solutions to age-old hard problems. While the core logic design has evolved adding multiple functionalities onto a chip, now called SoC, the structural composition of DFT (Design for Testability) has remained more or less same based on XOR-based compression… Read More
Addressing Moore’s Law with the First Law of Real Estate: Location, location, location
Design sizes and complexities have grown exponentially (it’s a Law!), and consequentially the task of silicon test has become proportionally more expensive. The cost of testing a device is proportional to the amount of test data that is applied, and therefore the time it takes, which in turn is proportional to both design size … Read More
An Universe of Formats for IP Validation
Although I knew about Crossfire’s capabilities for signing off quality of an IP before its integration into an SoC, there was much more to learn about this tool when I visited Fractal Technologies booth during this DAC. The complexity handled by this tool to qualify any type of IP for its integration into an SoC can be imagined by the… Read More
Saving Time and Money on Your Next SoC Project
Every SoC project that I know of wants to finish on time, under budget, and maximize profits per device. When I first started out doing DRAM design I learned that we could maximize profit by doing shrinks of existing designs, move from ceramic to plastic packages, and reduce the amount of time spent on a tester. Today, the economic … Read More
SoCs in New Context Look beyond PPA – Part2
In the first part of this article, I talked about some of the key business aspects along with some technical aspects like system performance, functionality, and IP integration that drive the architecture of an SoC for its best optimization and realization in an economic sense. In this part, let’s dive into some more aspects that… Read More
Mentor and ASSET Intertech Do a DFT World Tour
The Mentor Graphics test folks and ASSET Intertech have teamed up to provide a series of free DFT seminars in the US, Europe, and Asia. The first one is in Austin, TX on February 19, 2015, and the last is in Tokyo on April 24. Hereis the full list of locations and dates.
The morning session covers IJTAG. The new IEEE 1687 Internal JTAG (IJTAG)… Read More
