How to Quick Start Virtual Platform Development Umesh Sisodia CircuitSutra Technologies
Virtual Platform ? • SystemC use case that is gaining wide adoption in the industry • Simulation model of SoC / Electronics system that can run as fast as the real hardware • Can be used for embedded software development • Advanced debug and analysis features • Allows HW and SW development in parallel. Reduces Time to Market. Virtual Platform should be available early in the cycle
Challenges in VP development • Non availability of models. • It requires lots of efforts to understand modelingconcepts • No standard for modeling chip interfaces at transaction level (USB, Ethernet, UART, SPI, I2C, PCI etc..) • Tools are still evolving, how do you ensure that models are tool independent • 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 ?

Requirement • Standard TLM interfaces • TLM_UART • TLM_SPI • TLM_I2C • TLM_USB • TLM_ETHERNET • Methodology to develop the tool independent models • Off the shelf models of general purpose peripherals • Re-usable modeling infrastructure CircuitSutra have defined a set of TLM interfaces We can work with Accellera / IEEE to make these standard CircuitSutra Modeling Library (CSTML) Virtual Platform (VP-QSP)
Quick Start your VP project • CircuitSutra Modeling Library (CSTML) • Library built on top of SystemC & TLM2.0. 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 (SystemC, TLM2.0, STARC TLM Guidelines) • Will be continuously updated to adhere to upcoming standards (CCI, IP-XACT, UVM, SCV, SystemRDL) • 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-ARMCoreTile • VP-QSP-UART • VP-QSP-SPI • VP-QSP-Ethernet • VP-QSP-USB • VP-QSP-AUDIO • PCI, SATA, DDR, Imaging Sub System, Automotive SoC, Motor control … Reduce your VP development effort upto 80%
VP-QSP-UART UART Socket UART Socket UART Controller TERMINAL TLM UART • Sample model: PL011 UART • Similarly for other interfaces: SPI, Ethernet, USB, Audio
VP-QSP-ARMCoreTile Library of basic IP models which are required for any ARMCortexA9 & A15 based SoC. A minimal Virtual Platform that can boot Linux. VP of ARM reference boards: Core Tile Express A9, A15 and Motherboard uATX (ARM SMP Architecture) • Tested on Linux (32, 64), Windows (32, 64) • Can be integrated into any Virtual Platform environment • Other QSP being planned: Automotive SoC, Imaging SoC, Motor control etc..
