The datasheet provides the design specification for the MicroBlaze Debug Module (MDM). The MDM core enables JTAG-based debugging of one or more MicroBlaze processors.
Key Features and Benefits
Support for JTAG-based software debug tools
Support for debugging up to 32 MicroBlaze processors
Support for synchronized control of multiple MicroBlaze processors
Support for a JTAG-based UART with a configurable AXI4-Lite interface
Based on Boundary Scan (BSCAN) logic in Xilinx devices
Direct JTAG-based access to memory with a configurable AXI4 master interface
Configurable software access to debug functionality through the AXI4-Lite interface
Support for cross-trigger between connected MicroBlaze cores, Zynq-7000 Processing System and Integrated Logic Analyzer (ILA) cores
External trace function to funnel program trace from connected MicroBlaze cores to external interfaces
