Continuing Challenges For Open-Source Verification


Experts at the Table: This is the last part of the series of articles derived from the DVCon panel that discussed Verification in the Era of Open Source. It takes the discussion beyond what happened in the panel and utilizes some of the questions that were posed, but never presented to the panelists due to lack of time. Contributing to the discussion are Ashish Darbari, CEO of Axiomise; Serge L... » read more

A Price To Be Paid


Ancient wisdom says you should be careful what you ask for, because you just might get it. This was certainly true many times during my career within EDA, and I am sure it is still happening today. Sometimes the outcome was not what was wanted, or the price was higher than expected. As an example, consider VHDL, the language that was meant to correct the problems of Verilog. One of the probl... » read more

Invent A New Way To Do Your Job


My friends own a farm in the southwest of France, and though I spent most of my recent decades around big cities, my village-raised roots are sending me working in the fields every time I have the time. I don’t really care what I’m assigned to, as long as soil, the nearby forest trees, and the sky (preferably blue) will take part. If the job consists of repeating actions, I like to come up ... » read more

Scaling Simulation


Without functional simulation the semiconductor industry would not be where it is today, but some people in the industry contend it hasn't received the attention and research it deserves, causing a stagnation in performance. Others disagree, noting that design sizes have increased by orders of magnitude while design times have shrunk, pointing to simulation remaining a suitable tool for the job... » read more

Virtuoso ADE Assembler


Cadence Virtuoso ADE Assembler is an advanced design and simulation environment that extends the capabilities of Virtuoso ADE Explorer, adding all the tests needed to fully verify a design over all operational, process, and environmental conditions. As more analysis is required, users can take incremental advantage of the Virtuoso Variation Option to do more advanced statistical analysis on the... » read more

Hardware-Software Co-verification (ARM CPU)


In every complex SoC verification process, it is necessary to activate the CPUs during verification and to check the operation of the software they execute alongside the test’s scenarios. At a minimum, basic scenarios such as “boot rom execution” are tested, but in many cases, further scenarios are required. The CPUs themselves are usually proven IPs, but in order to verify their integrat... » read more

Trends In FPGA Verification Effort And Technology Adoption


The more we know about the bigger picture, context, historical and projected trends, or simply how other people do the same thing we do, the more efficiently and successfully we can do our specific jobs. This perspective also informs the EDA industry in how to best assist and sustain the needs of the FPGA and ASIC engineering communities. Providing this kind of information is the reason we c... » read more

Early Detection Of Reset Domain Crossing Errors


Many aspects of system-on-chip (SoC) designs are growing, including the numbers of gates, memories, clock domains, reset domains, power domains, on-chip buses, and external interfaces. A recent blog post focused on reset domain crossings (RDCs) and the requirements for effective pre-silicon verification of these trouble-prone structures. If properly applied, a solution meeting these requirement... » read more

Designing Secure and Trusted Silicon Using Shift-Left in Verification


Designing secure silicon requires the design to be stable at all times, it shouldn't enter unknown states at any time to make it vulnerable from the security point of view. This paper identifies different sources of instability such as combinational feedback loop, unguarded clock and reset crossing, unguarded power crossing, etc. These instabilities can lead to unknown value propagation and hig... » read more

Standards, Open Source, and Tools


Experts at the Table: Semiconductor Engineering discussed what open source verification means today and what it should evolve into with Jean-Marie Brunet, senior director for the Emulation Division at Siemens EDA; Ashish Darbari, CEO of Axiomise; Simon Davidmann, CEO of Imperas Software; Serge Leef, program manager in the Microsystems Technology Office at DARPA; Tao Liu, staff hardware engineer... » read more
