To begin a simulation, an AP and its algorithm must first be selected. To do this, select the ``AP/ALG SELECT'' button. An overlay for this purpose will appear. You will notice that the word ``SELECTED'' appears under this button whenever the overlay is popped up. This is important since MPSAS has a few configuration overlays, and switching between them will require popping some overlays up and others down.
On the the AP/ALGORITHM SELECTION overlay you will notice a list of supervisor and non-supervisor APs, several windows and buttons for selecting an algorithm, and three buttons at the bottom right corner. The ``RESET'' button does exactly what it sounds like it does - it clears out any current configuration information and prepares MPSAS to start again from the beginning.
The other two buttons, ``SUPE@DEV'' and ``SINGLE AP'', select the simulator's mode. The default mode is the simulation of a single AP, so for this section it need not be selected. However, if you were doing a simulation of a supervisor at the device-level and wanted to change over, you would do so by selecting the ``SINGLE AP'' button (a reset of MPSAS will be performed internally whenever either of these buttons is selected).
The algorithm or AP can be selected in either order. For demonstration here, we'll assume you first select the AP. Simply click on the AP in the list to be simulated. This action will be reflected in the messages window. An algorithm is then selected using the file-selection windows, lists, and buttons. Your current directory should appear in the box marked ``Filter'' and the files within it should appear under ``ALGORITHM FILE NAMES''. If this is not the directory from which you want to select your MPSL ``.PORT'' file, you can edit the ``Filter'' box to reflect the desired directory and then follow by pressing the ``Filter'' button. You can also manipulate the directory selection window. Select a file from the ``ALGORITHM FILE NAMES'' and it should appear in the ``Selection'' box. As another alternative, you can also directly type a file name (along with its directory name) into the ``Selection'' box. Once this box reflects the desired file you can hit the return key or press the ``OK'' button to select the algorithm.
MPSAS will pause while the data from this file is being loaded and MPSAS is prepared with a default configuration of device states and beam settings. A success message will appear in the message window, and you are ready to begin configuring devices and beam settings. Press the ``AP/ALG SELECT'' button once again to pop down this overlay out of your way.
Now that an AP and algorithm have been selected, selection of the ``AP/ALG LIST'' button will pop up a moveable, diagnostic window that displays information about the configuration of the current simulation. It contains AP names, whether the AP is a supervisor or not, whether an algorithm has been properly loaded for the AP or not, and the name of the algorithm. This information is trivial for the simulation of a single AP, but this list can become quite detailed and helpful when performing a simulation of a supervisor at the device level. More on that will follow in the section that pertains to it.
With an AP and algorithm selected, the configuration of devices and beam settings can begin. To configure devices (or to set algorithm ``operand-equalities''), select the ``OP-EQ CONFIG'' button to pop up the operand-equality configuration overlay. To configure the beam settings, select the ``BEAM CONFIG'' button to pop up the beam configuration overlay. As with the ``AP/ALG SELECT'' button, you will notice the word ``SELECTED'' appears under these buttons when the corresponding overlay is popped up as an aid when switching between the three configuration overlays.
