Freescale develops virtual prototypes

Freescale Semiconductor is expanding its development ecosystem to include virtual prototypes for its automotive Power Architecture microcontroller (MCU) portfolio using technology from Vast Systems.

These virtual prototypes will enable automotive developers to tackle growing software intricacies and speed up time to market.

Powertrain management systems have grown in complexity and performance to meet emissions and fuel efficiency standards, while industry demands for quality, reliability and faster time to market continue to increase.

The automotive ecosystem is responding to these challenges and virtual platforms have emerged as a compelling solution.

Vast Systems technology enables high cycle count accuracy, fast simulation speed and the functional accuracy required by many electronic control unit (ECU) suppliers.

These automotive system suppliers use simulation and modelling strategies as an effective substitute for the target hardware.

'Automotive suppliers operate in a high-pressure environment where speed and zero defects are paramount, and developing highly complex software adds to the challenge,' said Peter Schulmeyer, Freescale's director of strategy for automotive MCUs.

'Virtualisation addresses these requirements by providing automotive developers with early access to pre-silicon development, key technology and validation capabilities.' The 32bit MCU architecture for automotive powertrain management systems, Power Architecture technology, offers developers the combined benefits of cost-effective performance, advanced features and functionality, plus extensive third-party tool support that now includes virtual system prototypes (VSPs).

VSPs are available for Freescale's MPC5554, MPC5566, and MPC5565 Power Architecture MCUs.

These modelling solutions are built on the Virtual Processor Models (VPMs) from Vast Systems for the E200Z6 core and the enhanced timer processing unit (ETPU).

The solutions also are integrated with System C based peripheral models to help ensure a virtual replication of the specific device.

Using traditional tools, compilers, debuggers and integrated development environments (IDEs), powertrain system engineers can work with virtual hardware to develop software, test/validation suites and perform system architecture analysis before receiving silicon samples.

Freescale plans to add model availability to select current and future 32bit MCU products for advanced safety, body electronics and next-generation powertrain applications.
