Solving the System-Level Design Riddle October 2014
Solving the System-Level Design Riddle October 2014 What is the System Design Riddle? With no errors? Then marketing says they need it… Sooner Onbudget? With higher performance How do I complete my design ontime? In less area Sooner? Sorry, I meant early… …maybe you can drop a feature?

No, not entirely • Using Sonics and other high-quality IP will aid greatly • But there are limitations that good IP alone doesn’t solve - Your design methodology is probably wrong, though it may be the best you can do today 5 October 2014 Sonics, Inc. © 2014, all rights reserved What’s wrong? Waterfall Methodologies Specification Prototype Design Simulation Verification Emulation Physical Design 6 October 2014 Software Sequential operations • Little parallelism Changes in one phase may result in a reset of all downstream steps While design reuse (and use of purchased IP) is allowed, it cannot be fully exploited If one feature is causing a delay, it may be impossible to move forward with the rest of the design until it is resolved In general, the focus is on the process, rather than the desired outcome It’s easy to see the problems with the waterfall method. It assumes that every requirement can be identified before any design or coding occurs. Reasons for Changing IC Methodology Some drivers for change Consumer products • Short release cycle • Low power, but still always on • Security • Design costs IoT • Starting design without a complete spec Makimoto’s wave shifts emphasis from standardization to customization System companies are in best position to assume product risk 7 October 2014 Desired new attributes Ability to make reasonable progress with an incomplete specification To better solve modern design challenges: • Time-to-market • Power • Security Ability to easily ship “on-time”/early with a reduced feature set Improved relationship between architectural, logical, physical, and software design Why is Sonics leading this? 100% 250 90% 70% 60% 150 50% 40% 100 30% 20% 50 10% 0% Percent of Reuse Sonics, Inc. © 2014, all rights reserved 2018* 2017* 2016* 2015* 2014* 2013 2012 Avg.

The participants didn't agree about much, but they found consensus around four main values: • Individuals and interactions over processes and tools • Working software over comprehensive documentation • Customer collaboration over contract negotiation • Responding to change over following a plan Requirements Test & Feedback Architecture & Design Development “The Agile movement proposes alternatives to traditional project management. Agile approaches 11 are typically used in software development to help businesses respond to unpredictability.” October 2014 HW and IC Design Teams Must Evolve Yesterday Tomorrow Component-Level Aggregation System-Level Architecture One-time Usage Platform Reuse Hierarchical Requirements and Stepwise Design Management Concurrent Engineering and Agile IC Methodology Dedicated Resources Shared Resources 12 October 2014 What an Agile IC Methodology Might Look Like Waterfall Specification Prototype Design Simulation Verification Emulation Physical Design 13 October 2014 Time What an Agile IC Methodology Might Look Like Agile IC Methodology Specification Prototype Design Simulation Verification Emulation Physical Design Time Change the slope!
