Support for additional bus protocols has been added to Carbon Design's Virtual System Prototype (VSP) product line in the form of bus-functional models or transactors. These models for the PCI, PCI-X, USB 2.0 Host, and double-data-rate SDRAM protocols provide a communication layer from abstract functions, such as reads and writes, to pin-level devices listening and/or responding on a bus.
The combination of a transactor and a virtual hardware model produced using Carbon Design's methodology creates a very fast transaction-level model (TLM) that's easily integrated into modeling environments that include instruction-set simulators, idealized behavioral models, and cycle-accurate models. The transactors are available now as options to the VSP product line. Pricing per seat is based on an annual subscription volume model.
