3.5. Controlling the Sequencer using System Console

The System Console tool provides access to the Sequencer registers (present in the Sequencer Monitor block) through the Avalon® memory-mapped interfaces.

To use the System Console tool, your design must contain a Platform Designer subsystem with both the JTAG to Avalon® Master Bridge and Alignment Bridge enabled. Connect the JTAG to Avalon® Master Bridge through the Alignment Bridge and to the Avalon® Slave interface of the Sequencer Monitor. The example design already contains these components, but they are disabled. To enable them, select the checkboxes to the left of the component and press F5 to refresh the interconnect. The following figure shows a system that provides control access to both the PMBus* as well as JTAG interfaces.
