1.2.1.1. Overhead Logic

Any debugging tool that requires a JTAG connection requires SLD infrastructure logic for communication with the JTAG interface and arbitration between instantiated debugging modules. This overhead logic uses around 200 logic elements (LEs), a small fraction of the resources available in any of the supported devices. All available debugging modules in your design share the overhead logic. Both the Signal Tap logic analyzer and the LAI use a JTAG connection.
