Configuring trace lines (DSTREAM and RVT2 only)

If you have a DSTREAM unit or RVT2 unit, you can configure delays on the trace lines. To do this:

  1. Open the RVConfig utility.

  2. If you have already configured a debug hardware unit, select Open from the File menu to locate and open the corresponding configuration file.

    Otherwise:

    1. Connect to the required debug hardware unit.

    2. Create a new debug hardware configuration.

  3. Select the Trace node in the tree control. The following figure shows an example:

    You can delay each line by a specified amount of time (expressed in picoseconds, in 75ps intervals). Default delays are configured into the unit, and you are able to delay each signal by a specified amount relative to these defaults, allowing for variations in target hardware.

    You can also invert the clock so that data is sampled on the falling edge (rather than on the rising edge) of the clock. To do this, select the True/False checkbox. The default is False (unchecked).

Note

Some debuggers have limitations when tracing with DSTREAM. See your debugger documentation for details of the trace capabilities of your debugger.
