Crossfire Baseline Checks for Clean IP Part II

Crossfire Baseline Checks for Clean IP Part II
by Daniel Nenni on 10-10-2018 at 7:00 am

In our previous article bearing the same title, we discussed the recommended baseline checks covering cell and pin presence, back-end, and some front-end checks related to functional equivalency. In this article, we’ll cover the extensive list of characterization checks, that include timing arcs, NLDM, CCS, ECSM/EM, and … Read More


Crossfire Baseline Checks for Clean IP at TSMC OIP

Crossfire Baseline Checks for Clean IP at TSMC OIP
by Daniel Nenni on 09-26-2018 at 12:00 pm

IP must be properly qualified before attempting to use them in any IC design flow. One cannot wait to catch issues further down the chip design cycle. Waiting for issues to appear during design verification poses extremely high risks, including schedule slippage. For example, connection errors in transistor bulk terminals where… Read More


55DAC Trip Report IP Quality

55DAC Trip Report IP Quality
by Daniel Nenni on 07-09-2018 at 7:00 am

This year I signed books in the Fractal booth (compliments of Fractal) and let me tell you it was quite an experience. IP quality is a very touchy subject and the source of many more tape-out delays than I had imagined. As it turns out, commercial IP is the biggest offender which makes no sense to me whatsoever. Even more shocking, one… Read More


Fractal Technologies Joins TSMC Open Innovation Platform EDA Alliance

Fractal Technologies Joins TSMC Open Innovation Platform EDA Alliance
by Daniel Nenni on 06-18-2018 at 7:00 am

In case you missed it, Fractal is now officially part of the TSMC EDA Alliance. Fractal Crossfire is the leading IP and Library QA tool used by TSMC and many of TSMC’s customers so this is for the greater IP good, absolutely. Fractal has also released a new white paper “Setup Generation for Fractal Crossfire” that we can talk about but… Read More


Webinar: IP Quality is a VERY Serious Problem

Webinar: IP Quality is a VERY Serious Problem
by Daniel Nenni on 05-25-2018 at 12:00 pm

We just completed a run through of the upcoming IP & Library QA webinar that I am moderating with Fractal and let me tell you it is a must see for management level Semiconductor Design and Semiconductor IP companies as well as the Foundries. Seriously, if you are an IP company you had better be up on the latest QA checks if you want … Read More


Cross View Static Validation

Cross View Static Validation
by Alex Tan on 05-08-2018 at 12:00 pm

Improper handling of design validation could simply translate into a debugging exercise. In mainstream RTL2GDS flow, design implementation involves a top-level integration and lower-level block developments. These lower-level components, comprising of macros, IPs and standard cells are subjected to frequent abstraction… Read More


CEO Interview: Rene Donkers of Fractal Technologies

CEO Interview: Rene Donkers of Fractal Technologies
by Daniel Nenni on 02-28-2018 at 7:00 am

We (SemiWiki) have been working with Fractal for close to five years now publishing 25 blogs that have garnered more than 100,000 views. Generally speaking QA people are seen as the unsung heroes of EDA since the only time you really hear about them is when something goes wrong and a tapeout is delayed or a chip is respun.

FinFETs really… Read More


Good Library Hygiene Takes More Than an Occasional Scrub

Good Library Hygiene Takes More Than an Occasional Scrub
by Bernard Murphy on 10-26-2017 at 7:00 am

You don’t shower only before you have to go to an important meeting (teenagers excepted). Surgical teams go further, demanding a strict regimen of hygiene be followed before anyone is allowed into an operating room. Yet we tend to assume that libraries and physical IP (analog, memories, other physical blocks) are checked and pronounced… Read More


Visual Quality

Visual Quality
by Bernard Murphy on 06-12-2017 at 7:00 am

A few years ago, I started looking at data visualization methods as a way to make sense of large quantities of complex data. This is a technique that has become very popular in big data analytics where it is effectively impossible to see patterns in data in any other way. There are vast numbers of different types of diagram – treemap,… Read More


Power Checks for Your Libraries

Power Checks for Your Libraries
by Bernard Murphy on 05-12-2017 at 7:00 am

When your design doesn’t work, who owns that problem? I don’t believe the answer to this question has changed significantly since semiconductor design started, despite distributed sourcing for IP and manufacturing. Some things like yield can (sometimes) be pushed back to the foundry, but mostly the design company owns the problem.… Read More
