This component implements a 1-bit digital data logger that creates a log file in the Verilog Value Change Dump (VCD) format.
This file can be viewed by an external application such as
GTKWave.
Using an external waveform viewer may be more convenient than VMLAB's scope window when dealing with a very large amount of trace data.
