Debugging <strong>and</strong> signal tracing<br />
• Signal tracing can be done in SystemC by using a so<br />
called VCD (Value Change Dump) format file<br />
• A VCD file is a text format file containing the activity<br />
of the signals which need to be traced<br />
• A VCD file is created in 4 steps:<br />
– Open the VCD file<br />
– Select the signals to be traced<br />
– Start simulation: VCD file is written<br />
– Close the trace file
