Abstract: The disclosure contains descriptions of various methods and systems for accelerating the execution of a virtual prototype simulation. Acceleration may be achieved, for example, by providing two or more redundant virtual communication paths for access made by virtual models of a virtual prototype of a hardware design to provide for both accelerated access transactions and time-accurate access transactions. A model having such redundant virtual communication paths is referred to herein as a “multimode model.

Abstract: A method including accessing a first virtual prototype configured to perform a first simulation of a hardware design, identifying checkpoints within the first virtual prototype, each checkpoint including a storage state and/or behavioral state, and determining breakpoints for dividing execution of a second virtual prototype into a series of execution segments, where the second virtual prototype is configured to perform a second simulation of the hardware design, the second virtual prototype includes virtual models representing a separate portion of the hardware design, each virtual model representing a same portion of the hardware design as a corresponding virtual model of the first virtual prototype.

Abstract: System and methods for generating a software object that simulates the operation of a hardware device from a register transfer level description of the device written in a hardware description language, such as Verilog. The invention uses global analysis techniques (i.e., analysis of the design of the electronic device as a whole) to produce cycle accurate simulations of hardware devices. These global analysis techniques include generation of a static schedule for the simulation, based on clock edges and other selected signals present in the design. In some embodiments, reusing results from a previous simulation optimizes the simulation. In some embodiments, the software object that is generated may be linked with software that is being developed or tested for use with the hardware that is simulated by the software object. The software that is being developed or tested may interact with the simulation using a high-throughput application program interface (API).

Abstract: System and methods for analyzing the design of the hardware device as a whole, rather than in fragments. This provides a basis for a high-performance simulation of the hardware device from a register transfer level description of the device written in a hardware description language, such as Verilog.

These global analysis techniques include generation of a static schedule for the simulation, based on clock edges and other selected signals present in the design.
