Updates for Effective Collaboration

Updates for Effective Collaboration
by Paul McLellan on 07-09-2015 at 7:00 am

Managing any design data management system requires a policy on how often users should be submitting their changes to the central repository. If users commit frequently with less local testing then other users will more likely see errors. If commits are done less often, but with better testing, then other users are protected from… Read More


WarpStor, the Data Tardis: Small on the Outside, Large on the Inside

WarpStor, the Data Tardis: Small on the Outside, Large on the Inside
by Paul McLellan on 05-28-2015 at 7:00 am

There is a data explosion:

  • IBM says that 90% of all data was created in the last 2 years
  • Smartphone processor development requires 100GB of data per engineer
  • Android testing requires 30GB times the number of tests times the number of testers
  • Biotech simulation, game development and more all require enormous amounts of data

This … Read More


Top 10 Reasons to Use Industry-standard Data Management

Top 10 Reasons to Use Industry-standard Data Management
by Paul McLellan on 04-21-2015 at 7:00 am

Should a semiconductor/IP company use a proprietary data-management (DM) environment? Or even develop their own? After all, every company is unique and developing a unique DM allows a perfect match of just what is required for that particular company. And, in principle, a proprietary DM system can underpin the design management… Read More


The Earth is Not Flat; Neither is IP

The Earth is Not Flat; Neither is IP
by Paul McLellan on 03-29-2015 at 7:00 pm

Chip design is largely about assembling pre-designed IP, either developed in other groups in the same company, or brought in from a 3rd party, or occasionally developed within the SoC design group itself. But that makes it sound like it is a bunch of blocks linked together with some interconnect, but of course another important … Read More


Why Would You Leave Yahoo to Go Into EDA?

Why Would You Leave Yahoo to Go Into EDA?
by Paul McLellan on 02-06-2015 at 7:00 am

I sat down this afternoon with Peter Theunis, the CTO of Methodics. Conveniently their office is about a 15 minute walk from where I live so we could chat face to face.

Peter started programming when he was 8 and his first “product” was a weather system for orchards where sensors in the orchards would send information … Read More


Methodics Access Controls

Methodics Access Controls
by Paul McLellan on 01-20-2015 at 7:00 am

My PhD thesis is titled The Design of a Network Filing System. Yes, that was a research topic back then (and yes, we did call them filing systems not file-systems). One big chapter was on access controls. There are several problems with designing an access control system:

  • it needs to be possible to implement it efficiently
  • it needs

Methodology Help for Analog IC Designers

Methodology Help for Analog IC Designers
by Daniel Payne on 12-25-2014 at 7:00 am

Digital designers are more numerous than analog IC designers, and so they tend to get more attention from EDA vendors in terms of tools and automation methodologies. For an analog design team with specialists focused separately on schematics and layout there are several methodology questions that need to be addressed, like:… Read More


IC Design at ZMDI

IC Design at ZMDI
by Daniel Payne on 11-28-2014 at 7:00 pm

As a blogger I have the privilege of meeting many IC designers from around the world, mostly through contact on LinkedIn or from connecting at trade shows. Through a contact at DACI met up with Achim Graupner, a manager of methodology and design automation from ZMDI, then asked him for an interview to understand how his group does … Read More


Effective Bug Tracking with IP Sub-systems

Effective Bug Tracking with IP Sub-systems
by Daniel Payne on 10-31-2014 at 7:00 am

Designing an SoC sounds way more exciting than bug tracking, but let’s face it – any bug has the potential to make your silicon fail, so we need to take a serious look at the approaches to bug tracking. When using an IP or an IP subsystem in a design, the SoC integrators require some critical knowledge about this IP. The actual… Read More


IP and Design Management Done Right

IP and Design Management Done Right
by Daniel Payne on 09-30-2014 at 4:30 pm

At DACin San Francisco this past June I was able to visit and blog about two dozen EDA companies, however there were so many more products and events to see that I couldn’t possibly have enough time to enjoy them all. Fortunately for me there were plenty of videos made of vendor presentations, so this week I got caught up a bit by… Read More
