Using VDKs for Automotive Systems Development
This white paper discusses the quantitative and qualitative analysis of the return on investment from VDKs. The software content of automotive systems found in powertrain, chassis, safety, body and advanced driver assistance systems (ADAS) application is increasing. At the same time, the pressure to accelerate development time lines, improve reliability and maintain/reduce costs is also increasing. Automotive OEM, Tier 1 and semiconductor companies involved in embedded software development, integration and test need to integrate new tools and methodologies in their development process to address these new challenges.

Using Virtual Prototypes to Address the Growing Software Complexity in Automotive
This white paper explores how using virtual prototypes to model microcontrollers and electronic control units provide multiple benefits across the automotive supply chain. These include but are not limited to, the ability to develop software before hardware is available, the ability to integrate and test software stacks sooner and the ability to more thoroughly test functional safety aspects. Where time-to-market is the main driver for mobile applications, within the automotive industry the use of virtual prototypes aims mostly at improving quality and reducing safety risks, all while keeping the cost of software development and testing at bay.

Virtual Prototypes for Early Software Development: Requirements, Solutions and Use Cases
In previous white papers, we've looked at the demands of the rapidly changing market and how the use of virtual prototypes has evolved to help meet them. In this white paper, we look specifically at the challenges of developing some of the hardware-dependent software layers - namely boot ROM code, OS bring-up, driver development - used in fast-evolving mobile devices and how to use virtual prototypes to 1) Start developing software far in advance of hardware availability 2) Break the gating dependencies between layers in the software stack to enable parallelized development and 3) Develop the silicon validation suite before hardware is available.

Virtual Hardware "In-the-Loop": Earlier Testing for Automotive Applications (Part 1)
This whitepaper is the first one in a series of publications that will describe the concept of virtual hardware "in-the-loop" (vHIL). The goal of vHIL is to frontload the testing process by enabling software teams to create and run their software tests before the actual ECU hardware is available. Higher quality tests, higher quality software and a more streamlined "in-the-loop" flow is the intended outcome of this solution. Besides describing how vHIL fits in the general Model-In-the-Loop (MIL) - Software-In-the-Loop (SIL) - Hardware-In-the-Loop (HIL) process, this first whitepaper describes in more detail how a virtual prototype model created with Synopsys Virtualizer can be integrated with a MathWorks Simulink plant model. This integration is fundamental for enabling a vHIL solution.

Virtual Prototypes: When, Where And How To Use Them
An innovation-hungry public and a highly competitive marketplace make for short product cycles, while the sophistication and performance expected of digital devices grows with every new product generation. Heterogeneous multiprocessing, where different cores do specialized work, has become the industry norm inside those devices, radically increasing the amount of software needed, the importance of software in managing system resources and the possibility for error among interconnected, interdependent subsystems. Traditional tools and methods for embedded software development are no longer up to the jobs software is being asked to perform within the schedules engineering teams are required to meet.

Designing the Right Architecture
In this white paper, we present a tool-assisted system-level performance analysis flow for interconnect and memory performance optimization using Synopsys Platform Architect. This environment allows the rapid creation of system-level performance models and the parallel simulation of many design configurations to investigate a wide range of architectural options. After a brief motivation and introduction of the flow we discuss the results of a design project, where Platform Architect has been used to optimize the performance of a multicore mobile platform SoC.

Virtual Prototyping for Energy Efficient Mobile Platform Design
This white paper introduces the complexity of power management at the software level for mobile devices by means of Linux and Android. The complexity of hardware power management is mirrored in software. A single defect in the power management scheme can have a catastrophic impact on the standby time of a mobile device. We outline how Synopsys Virtual Prototypes address major challenges in the bring-up and validation of power management software. Furthermore, we introduce how virtual prototypes can be used for software-centric power estimation and analysis.

Efficient Design and Verification of Digital Communication Systems
LTE and WiMAX are key contenders for next generation mobile phone system. Both standards are excellent examples to highlight the huge complexity involved in modern communication algorithms. This increasing complexity is the trigger for new design methodologies and tools. This white paper provides a detailed analysis on the elements that determine algorithm design and verification efficiency for LTE and WiMAX communications systems. The concept of efficiency is discussed for modeling, simulation, reuse, and verification. Different methodologies and simulation solutions are then compared, providing the reader with specific algorithm design requirements.

C/C++ for Complex Hardware Design
An increasing number of ASIC and FPGA designs are accelerating algorithms and applications directly in hardware (HW) circuits. These HW accelerator cores have become commonplace and are now a key part of product differentiation and the ability to meet market expectations in performance, cost and reliability. However, the implementation and verification of hardware acceleration cores is very difficult, especially due to the growing complexity of standards in video, imaging, wireless, and other multimedia and communications applications. RTL methodologies for IC design and verification are struggling to address this complexity in terms of productivity, available resources and time-to-market.

Debugging SuperSpeed USB Software Using Virtual Prototypes
Software is a critical component for the development of USB-based designs. In efforts to start software development early and to make it as productive as possible, design teams are often utilizing virtual and FPGA prototypes for software development prior to silicon. While FPGA prototypes can still be made available prior to silicon, virtual prototypes can be utilized even before RTL is available. This white paper describes how virtual prototype use models for hardware/software verification and the integration of the LeCroy analyzer software into Synopsys' DesignWare SuperSpeed USB verification environments help solve SuperSpeed USB IP development challenges.
