How to Quick Start Virtual Platform Development Umesh

How to Quick Start Virtual Platform Development Umesh Sisodia Circuit. Sutra Technologies

Virtual Platform ? q System. C use case that is gaining wide adoption in the industry q Simulation model of So. C / Electronics system that can run as fast as the real hardware q Can be used for embedded software development q Advanced debug and analysis features q Allows HW and SW development in parallel. Reduces Time to Market. Virtual Platform should be available early in the cycle

Challenges in VP development q Non availability of models. q It requires lots of efforts to understand modeling concepts q No standard for modeling chip interfaces at transaction level (USB, Ethernet, UART, SPI, I 2 C, PCI etc. . ) q. Tools are still evolving, how do you ensure that models are tool independent q To use advanced debug features you may have to do tool specific modifications in the model Can Virtual Platform be available early in the cycle ? For low end applications does it make economic sense to build a VP ?

Challenges in VP development q Registers Ethernet Controller Protocol Handling TLM Ethernet Protocol Backend Ethernet Driver (Host PC) Switch Ethernet Controller

Requirement q Standard TLM interfaces q. TLM_UART q. TLM_SPI q. TLM_I 2 C q. TLM_USB q. TLM_ETHERNET Circuit. Sutra have defined a set of TLM interfaces We can work with Accellera / IEEE to make these standard q Methodology to develop the tool independent models Circuit. Sutra Modeling Library (CSTML) q. Off the shelf models of general purpose peripherals q Re-usable modeling infrastructure Virtual Platform (VP-QSP)

Quick Start your VP project q Circuit. Sutra Modeling Library (CSTML) Library built on top of System. C & TLM 2. 0. This is a collection of convenience classes and utilities that ease the model development activity. Relieves the modeling engineers for the complexity of various modeling concepts (abstraction, TLM rules etc. . ) Enables tool independent model development. Model skeleton is automatically generated using a script Compliant with standards (System. C, TLM 2. 0, STARC TLM Guidelines) Will be continuously updated to adhere to upcoming standards (CCI, IP-XACT, UVM, SCV, System. RDL) q Virtual Platform – Quick Start Package (QSP) Library of basic models and modeling infrastructure that can be used to quick start a Virtual Platform project VP-QSP-ARMCore. Tile VP-QSP-UART VP-QSP-SPI VP-QSP-Ethernet VP-QSP-USB VP-QSP-AUDIO PCI, SATA, DDR, Imaging Sub System, Automotive So. C, Motor control … Reduce your VP development effort upto 80%
