Abstract

Disclosed is a method (or a system or a non-transitory computer readable medium) for recreating states of an embedded processing unit of a design under test (DUT). In one aspect, a host system configures an emulator to implement the DUT. The DUT includes the embedded processing unit and a memory unit. The host system configures the emulator to execute design instructions for testing an operation of the DUT through the embedded processing unit. The host system receives a stream of values stored by the memory unit of the DUT. The values indicate execution results of the design instructions executed by the embedded processing unit. The host system stores the stream of the values and generates a log file for recreating one or more states of the embedded processing unit based on the stored stream of the values.
