System Design with Early System Exploration

November 30, 2015

System Design creates the right “look and feel” of the product for the target application. System design enables early architecture exploration using incomplete information to create accurate system requirements. Early system design creates the highest quality product with the required response time and throughput; optimized for power consumption; and has the lowest cost. The end […]

Estimating Execution Time using Discrete-event Simulation for large complex Aerospace Systems

November 12, 2015

Emerging, high-speed bus technologies and migration to multi-core platform requires detailed high-level system analysis before scheduling implementation. Systems engineers run multi-variant workloads to conduct a battery of trade-offs including task response time vs. power dissipated; distributed vs. centralized processing; and throughput vs. cost. Analytical means and over-provisioning cannot handle the system complexity required to identify […]

Fine-Grained Performance and Power Analysis

November 12, 2015

Architecture exploration, performance and power analysis early in the design flow are mandatory in modern SoC design flow due to complex multi-threaded applications and multi-core processing requirements. Instruction Set Simulator or ISS of a selected processor plays a very important role. However, Current Instruction Set Simulators (ISS) and platform modelers have detailed functional execution, tuned […]

Selecting right processor for Next-Gen SoC

November 11, 2015

Have you ever thought of having a systematic approach for selecting right processor for your upcoming SoC? Absolutely, every day we all think about it and finally go with our “gut feeling”. Selection of processor is becoming extremely complex day by day and is not at a straightforward task as opposed to early days of […]

Certification of IMA for Avionics System

November 3, 2015

Real-time constraints, reconfigurability and safety have a direct impact on architecture design and on the validation/certification process, at the aircraft and system level. Current certification of Integrated Modular Architecture (IMA) avionics using network calculus cannot accurately predict communication and processing latency. Here is a solution for IMA-based avionics to generate certification tests, conduct what-if analysis, […]

Incremental design issues in Avionics System

October 12, 2015

Incremental Designs are common and highly practiced approach in every avionics system design process. Designing a new system from ground-up is prone to multiple issues right from technical to overall cost required. Even a minor up gradation of application software may cause huge impact on the overall system performance and power consumption. Predicting system performance […]

Early system analysis of AVB based Systems

October 10, 2015

Ethernet is widely used for all kinds of applications. However, for demanding multimedia streaming applications in a fully-loaded network, Ethernet is not the right choice due to its limited Quality-of-Service (QoS) support. IEEE 802.1 Audio/Video Bridging (AVB) standard, an extension to legacy Ethernet, provides the QoS features needed for multimedia streaming such as time synchronized […]

Multi-core, Power Optimization- All about system design and exploration

October 10, 2015

Multi-core, mutli-thread, multi-processors, lower power, more performance, shorter response time, higher throughput.  These are all the sales pitch and potential of these new technology.  Be it Nvidia with a large number of small cores, or the Monarch with it is local embedded memory or the Intel architectures or the Snapdragon, multi-cores are the new approach. […]

Modeling of Software Process using VisualSim Architect

October 10, 2015

Over the past few decades the software industry has been assailed by numerous accounts of schedule and cost overruns as well as poor product quality delivered by software development organizations in both the commercial and government sectors. One of the areas of research which addressed the problem effectively is Software process modeling and simulation. The […]

Linking System-level modeling to RTL and Source code

October 10, 2015

Everyone is always looking for this elusive link from high-level conceptual design to implementation. Also, what is high-level and what is implementation also depends on the team charter. Is it a functional model or timing or a power model? Is the implementation in RTL (Verilog or VHDL) or C, C++ or Java for software? Or […]

Integrated Vehicle Health Management(IVHM) system development using VisualSim Architect

October 10, 2015

One of our recent work was evaluation of the “Integrated Vehicle Health Monitoring(IVHM)” of electronic systems using VisualSim for modeling and simulation. In the current scenario most of the solutions are using analytical methods to evaluate “success” or “failure” of a system which is obviously a critical task. We have created a very detailed level models […]

ESL and IC-only Solutions are not the same

October 10, 2015

Most articles on ESL cover the IC-only design or a virtual prototyping environment for software development. Articles would be accurate if systems were simple and ICs were the only parts in a complete product. Unfortunately for an already confused industry, everyone mixes ESL and IC, seeming to imply that ESL tools aren’t needed. Remember that […]
