Figure 7-4: Example: Defining marker traces (CONTROL LENGTH tag is not used)
To define a restart marker and a frame start marker, use the following tags:
1. The waveform is 300 samples long, i.e. set {SAMPLES: 300} .
2. Set two [TRACE] LIST tags:
● For Marker 1 that acts as a restart marker:
{MARKER LIST 1: 0:1; 10:0; 299:0}
● For Marker 2 that marks each frame start:
{MARKER LIST 2: 0:1; 10:0; 99:0}
3. Do not use the CONTROL LENGTH tag.
The length of the repeated patterns is determined by the last sample number in the
[TRACE] LIST
, that is the last { Pos: State} .
Example: How the CONTROL LENGTH tag influences the processing of the
traces
For the example on Figure 7-4 , use the same marker traces and set the
CONTROL
LENGTH
tag, e.g.
{CONTROL LENGTH: 150}
.
Figure 7-5: Example: Processing of control signals if the CONTROL LENGTH tag is used
The length of all control signals is determined by the
CONTROL LENGTH
. Observe how
the marker traces are processed. In this example, both marker traces are repeated
each 150 samples.
