2. Virtual Platform should be available early in the cycle
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

3. Challenges in VP development
Non availability of models.
It requires lots of efforts to understand modeling concepts
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 ?

5. CircuitSutra Modeling Library (CSTML) Virtual Platform (VP-QSP)
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

6. Reduce your VP development effort upto 80%
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
