  • Physically-Aware Synthesis: This Time it’s Different

    RTL Compiler Physical has been available for about 2 years now, and we're getting more customers all the time. But we still get the question - how is this different from physical synthesis tools like PKS or Physical Compiler? Those of you that were around 10 years ago when physical synthesis was...

  • The Dangers of Excessive Guard Banding

    By Matt Rardon Synthesis Solutions I want to take a couple of minutes to talk about guard banding of constraints in logic synthesis. This approach was initially conceived to add a little bit of padding to the design to account for inaccuracies in synthesis modeling techniques and to provide some wiggle...

  • Where Oh Where is "number_of_routing_layers"?

    OK, I'll just do " set_attribute number_of_routing_layers 6 "... Error : The attribute is read-only. [TUI-26] [set_attribute] : attribute: 'number_of_routing_layers', object type: 'root' : Cannot set or reset read-only attributes. Hey, wait a minute! If you are faced with...

  • Blogs: What interests you? What do you want to read about?

    With the new blogging opportunities at Cadence, is there anything you'd like to read more about for frontend design? Stuff like: Early chip-planning/prototyping, synthesis (including physical-synthesis), formal verication, DFT, frontend methodologies, etc. My hope is for the blog topics to be informative...

  • "What is ChipEstimate?" plus a touch of RC-Physical x 2

    Day 2 @ CDNLive San Jose: Another interesting day - met quite a few people, some new, others I met the day before while co-presenting at two morning sessions, and also some of my fav customers. My focus-of-the-day - ChipEstimate awareness with a touch of RC-P. Here are some attendees' feedback: Question...

  • Logic Handoff Models at 45nm and Beyond

    CDNLive! Silicon Valley has been a good conference so far, lots of good papers and conversations. One thing I wanted to share was a panel discussion yesterday entitled "Logic Handoff Models at 45nm and Beyond." It was a great discussion, moderated by Ron Wilson of EDN, and on the panel were...

  • Feeling Restless ... CDNLive San Jose Conference Update!

    Ah yes ... my first blog here! I can't believe the freedom we're getting at Cadence, unfiltered blogging. :) I co-authored and helped deliver two presentations/papers yesterday with a couple of down-to-earth engineers. Thanks to everyone who was able to attend these sessions, it was fun meeting...

  • Some tips for predicting power consumption

    In my previous post , entitled “How do you predict power?”, I was actually looking for reader input via the comments. I should have been more clear on that….perhaps I am too accustomed to my 6-year-old son, who will supply a barrage of responses to even a rhetorical question. Anyway...

  • How do you predict power?

    You read stories about it – the device or chip that comes out and consumes more power than expected. Maybe the battery life isn’t what it was supposed to be (my current smartphone is a great example!). Or even worse, maybe there are failures because the excessive power density generates too...
