ABSTRACT:
A circuit arrangement and method detect external requests to access a memory array in a hardware simulation accelerator during performance of a simulation on a simulation model and access the memory array without halting the simulation in response to detecting the external request. Such functionality may be provided, for example, by detecting such external requests in response to processing a predetermined instruction in an instruction stream associated with the simulation model, where the predetermined instruction is configured to ensure a predetermined period of inactivity for the memory array. By doing so, the memory array can be accessed from outside of the hardware simulation accelerator during the processing of a simulation, and without requiring that the simulation be halted, thus reducing overhead and improving simulation efficiency.
