Inside UVM
By Vatsal Choksi - 26 Oct, 2017 - Comments: 0

We have all been witnesses to the rapid improvements of the iPhone processor chip every year. With the iPhone 8 featuring the newest A11 Bionic at 10 nm FinFET with 4.3 billion transistors, I can’t personally fathom the amount of the verification effort needed for this type of SoC - the required manpower and time to get the job done is absolutely mind-boggling. Thankfully, we have several pre... » read more

High Performance, Low Power, And Test: DFT’s Impact On System PPA And Safety
By Rob Knoth - 12 Oct, 2017 - Comments: 0

Back in the day, test was an afterthought in system design and implementation. It was a separate task that could be added to the end of a project schedule—essentially, a checkbox before sending a design for manufacture or during product qualification. Nowadays, test is no longer an afterthought, and we’ll see it continue to grow in importance. Safety-critical semiconductor applications h... » read more

System Coverage Undefined
By Brian Bailey - 28 Sep, 2017 - Comments: 1

When is a design ready to be taped out? That has been one of the toughest questions to confront every design team, and it's the one verification engineers lose sleep over. Exhaustive [getkc id="56" kc_name="coverage"] has not been possible since the 1980s. Several metrics and methodologies have been defined to help answer the question and to raise confidence that important aspects of a block... » read more

Tech Talk: eFPGA Test

Volkan Oktem, director of product applications at Achronix, explains how to design a test approach for embedded FPGAs, including how to plan for sufficient coverage and how much it will cost. https://youtu.be/aGXd8QH-BfY   Related Stories Tech Talk: EFPGA Acceleration When and why to use embedded FPGAs. » read more

Portable Stimulus Status Report
By Brian Bailey - 24 Aug, 2017 - Comments: 0

The first release of the Portable Stimulus (PS) standard is slated for early next year. If it lives up to its promise, it could be the first new language and abstraction for verification in two decades. [getentity id="22028" e_name="Accellera"] uncorked the PS Early Adopter release at the Design Automation Conference (DAC) in June. The standard has been more than two years in the making by t... » read more

When Is Verification Complete?
By Ann Mutschler - 24 Aug, 2017 - Comments: 0

Deciding when verification is done is becoming a much more difficult decision, prompting verification teams to increasingly rely on metrics rather than just the tests listed in the verification plan. This trend has been underway for the past couple of process nodes, but it takes time to spot trends and determine whether they are real or just aberrations. The Wilson Research Group conducts a ... » read more

Verification Unification
By Brian Bailey - 22 Jun, 2017 - Comments: 0

Semiconductor Engineering brought together industry luminaries to initiate the discussion about the role that formal technologies will play with Portable Stimulus and how it may help to bring the two execution technologies closer together. Participating in this roundtable are Joe Hupcey, verification product technologist for [getentity id="22017" e_name="Mentor, a Siemens Business"]; Tom Fitzpa... » read more

Safety Plus Security: A New Challenge
By Brian Bailey - 08 Jun, 2017 - Comments: 0

Nobody has ever integrated safety or security features into their design just because they felt like it. Usually, successive high-profile attacks are needed to even get an industry's attention. And after that, it's not always clear how to best implement solutions or what the tradeoffs are between cost, performance, and risk versus benefit. Putting safety and security in the same basket is a ... » read more

Verification Unification
By Brian Bailey - 25 May, 2017 - Comments: 0

There is a lot of excitement about the emerging [getentity id="22028" e_name="Accellera"] [getentity id="22863" e_name="Portable Stimulus”] (PS) standard. Most of the conversation has been about its role in [getkc id="11" kc_name="simulation"] and [getkc id="30" kc_name="emulation"] contexts, and in the need to bring portability and composability into the verification flow. Those alone are st... » read more

Whatever Happened to High-Level Synthesis?
By Brian Bailey - 16 May, 2017 - Comments: 0

A few years ago, [getkc id="105" comment="high-level synthesis"] (HLS) was probably the most talked about emerging technology that was to be the heart of a new [getkc id="48" kc_name="Electronic System Level"] (ESL) flow. Today, we hear much less about the progress being made in this area. Semiconductor Engineering sat down to discuss this with Bryan Bowyer, director of engineering for high lev... » read more
