Virtual platforms enable software developers to build drivers and test their code early using a virtual version. They bring software and hardware team to enable early software and early validation. As I can see, you’re talking in your "Plans for RISC-V in 2016 » presentation about SPI, I2C, I2S, UART IP, I think it would be interesting for the community to have a TLM LT level (for example) equivalent to ease hardware, driver development and testing.

Hi Guillaume. Thanks for getting in touch. My personal experience with
SystemC is through our Loki research project where we found a model of
the complete design to be useful for rapidly iterating on hardware
designs and to verify against with the RTL implementation that
followed. I have less experience using models for IP blocks in
isolation - perhaps you could expand on how you feel a loosely timed
model of SPI, I2C, ... could be exploited by the community? Although
much more challenging, I wonder if models for higher speed protocols
like USB or PCIe might be interesting.
