Abstract: Providing a unified view of multiple computer system simulations. A simulation process has a simulation thread that executes a plurality of computer system simulations. The simulation process also has a debug support thread that provides a unified view of the simulations. To provide the unified view, the debug support thread has an external interface, an internal interface to each of the simulations, and an interface converter that converts between the external interface and the internal interfaces. Thus, the external interface provides a unified view of the simulations. The external interface allows a single debugging platform to control and observe the simulations.

Abstract: Executing a simulation of a computer platform, the simulation including simulation models. A dynamic quantum is accessed whose current value specifies a maximum number of units of execution a simulation model is allowed to perform without synchronizing with another simulation model. The dynamic quantum may be received from a user. Respective simulation models are invoked for execution with the current value of the dynamic quantum provided to each of the simulation models. The method also comprises modifying the value of the dynamic quantum based on a simulation event.

Abstract: Protocol conversion is disclosed. A first transaction of a first protocol and a second transaction of a second protocol are accessed. From the accessed transactions, a plurality of protocol conversions are computed. Additional transactions of the first protocol and additional transactions of the second protocol can be accessed, and further protocol conversions applicable between the additional first and the second transactions can be computed. Based on at least some of the applicable protocol conversions, a combined controller that is able to convert between the transactions of the first and second protocols is generated. Instructions that are operable to describe the combined controller are stored in a computer readable medium.

Abstract: Translating to a hardware description language (HDL) from an architecture description language (ADL) is disclosed. An architecture description that is written in the ADL and has a hierarchical organization is received. Decoders are generated, described in the HDL, from the architecture description written in the ADL. Control signals are generated, described in the HDL, from the architecture description written in the ADL. The decoders are configured to output the control signals and the control signals are input to functional units in order to preserve the hierarchical organization of the architecture description written in the ADL.

Abstract: Generating a simulator from an architecture description. A target architecture model described in an architecture description language (ADL) is accessed. The model comprises a semantic representation of an instruction set for the target architecture. The semantic representation is translated to a behavioral representation. The simulator is automatically generated from the behavioral representation. A compiler may also be generated from the semantic representation.
