The Bandwidth calculation tab allows user to estimate the total bandwidth used in the A2B network. Bandwidth calculation is useful to design an efficient A2B network.
The following steps are involved in Bandwidth calculation
The “Chart Breakdown” tab allows user to get a breakdown chart, which will have detail of operation of each node.

Overall power consumption of the A2B network can be estimated using the Power Calculation tab. Power calculation can assist board designers in estimating power requirements for power supply design.
The following steps are involved in Power calculation
The “Power Breakdown” tab allows user to get a breakdown chart, which will have detail of power requirement of each node.

Bit errors generated over an A2B network can be monitored in the GUI. BERT calculation is useful to design an efficient error-free A2B network. BERT is supported both via I2C and SPI interfaces.
The following steps are involved in Bandwidth calculation
The Trace option in the Network properties window show in Figure 61 enables user to log various transactions and network events into a .txt file. Upon enabling this feature the A2B stack running inside SigmaStudio Plus captures all transactions as per the ‘Level’ and ‘Domain’ set. Figure 78 shows a sample Trace file generated for selected Level (Debug, Info, Trace3) and Domain (Plugin, Message, I2C). The Trace file gets saved inside the ‘Settings’ folder corresponding to the A2B schematic project file location.

The Sequence Chart option in the Network properties window show in Figure 61 enables user to view various transactions and network events as a rich graphical sequence diagram (.png).
The sequence diagram shows interactions between different stack modules arranged in time sequence and the messages exchanged between the stack modules to discover, configure and handle various network events.
The Sequence Chart file gets saved inside the ‘Settings’ folder corresponding to the A2B schematic project file location.
Following prerequisites shall be ensured to generate the sequence chart upon discovery completion.
Prerequisites:
Figure 79: Setting Path in Environment Variables
If the prerequisites are met and sequence chart option is enabled in the Network properties tab, then upon successful discovery of A2B network, the Sequence chart will be generated which can be viewed by clicking on the View button. A Sequence chart generated for a 3 node sample demo schematic is shown in Figure 80.

If the prerequisites are not met, then a pop up window will display the error message as shown in Figure 81.
