8.1.1. Planning Guidelines for Debugging Tools
|1||Select on-chip debugging schemes early to plan memory and logic requirements, I/O pin connections, and board connections.|
|2||If you want to use Signal Probe incremental routing, the Signal Tap Embedded Logic Analyzer, Logic Analyzer Interface, In-System Memory Content Editor, In-System Sources and Probes, or Virtual JTAG IP core, plan your system and board with JTAG connections that are available for debugging.|
|3||Plan for the small amount of additional logic resources used to implement the JTAG hub logic for JTAG debugging features.|
|4||For debugging with the Signal Tap Embedded Logic Analyzer, reserve device memory resources to capture data during system operation. Ensure that the JTAG signals have a clean timing.|
|5||Reserve I/O pins for debugging with Signal Probe or the Logic Analyzer Interface so you do not have to change the design or board to accommodate debugging signals later.|
|6||Ensure the board supports a debugging mode where debugging signals do not affect system operation.|
|7||Incorporate a pin header or mictor connector as required for an external logic analyzer or mixed signal oscilloscope.|
|8||To use debug tools incrementally and reduce compilation time, ensure incremental compilation is on so you do not have to recompile the design to modify the debug tool.|
|9||To use the Virtual JTAG IP core for custom debugging applications, instantiate it in the HDL code as part of the design process.|
|10||To use the In-System Sources and Probes feature, instantiate the IP core in the HDL code.|
|11||To use the In-System Memory Content Editor for RAM or ROM blocks, turn on the Allow In-System Memory Content Editor to capture and update content independently of the system clock option for the memory block in the IP catalog.|
If you intend to use any of the on-chip debugging tools, plan for the tool(s) when developing the system board, Intel® Quartus® Prime project, and design.
