ABSTRACT:
A method and corresponding equipment for emulation of a target programmable unit, which has at least one CPU, by means of an external emulation device, which is coupled to the target programmable unit by means of a communication link, comprising: transferring predetermined initialization data through the communication link to the emulation device for initializing the emulation; transferring through the communication link to the emulation device a CPU clock signal and emulation data; emulating the target programmable unit in the external emulation device using the transferred emulation data; ascertaining respective trace data from the emulation in the external emulation device and storing and/or outputting the trace data; deriving respective target integrity-control data and emulation integrity-control data from respective target-internal data and emulation-internal data; and transferring the derived target integrity-control data from the target programmable unit to the external emulation device.
