+/* The VCD input module has the following options:
+ *
+ * numprobes: Maximum number of probes to use. The probes are
+ * detected in the same order as they are listed
+ * in the $var sections of the VCD file.
+ *
+ * skip: Allows skipping until given timestamp in the file.
+ * This can speed up analyzing of long captures.
+ *
+ * Value < 0: Skip until first timestamp listed in
+ * the file. (default)
+ *
+ * Value = 0: Do not skip, instead generate samples
+ * beginning from timestamp 0.
+ *
+ * Value > 0: Start at the given timestamp.
+ *
+ * downsample: Divide the samplerate by the given factor.
+ * This can speed up analyzing of long captures.
+ *
+ * compress: Compress idle periods longer than this value.
+ * This can speed up analyzing of long captures.
+ * Default 0 = don't compress.
+ *
+ * Based on Verilog standard IEEE Std 1364-2001 Version C
+ *
+ * Supported features:
+ * - $var with 'wire' and 'reg' types of scalar variables
+ * - $timescale definition for samplerate
+ * - multiple character variable identifiers
+ *
+ * Most important unsupported features:
+ * - vector variables (bit vectors etc.)
+ * - analog, integer and real number variables
+ * - $dumpvars initial value declaration
+ * - $scope namespaces
