I already put my own MUXes in my Altera FPGA design to better utilize debug pins. is this solution better or not?

FPGA dynamic probe was designed to have minimal intrusion in both the design flow and the design itself. Here are the top areas where the FPGA
dynamic probe solution will save you work and time, even if you already use your own MUXes.
1. FPGA dynamic probe does not require you to modify your HDL code. Alteraâ€™s LAI Interface Editor lets you specify details of the MUX and automatically includes it in your FPGA. Teams not using FPGA dynamic probe must modify HDL code to include MUXes.
2. Control of which signals are presented for measurement is done from the logic analyzer in about a second (only 2 mouse clicks). Teams not
using FPGA dynamic probe must design in special capability (such as changing register values) to change which signals are presented to IO pins.
3. With FPGA dynamic probe, signal names are imported from the FPGA Design Tools and automatically updated in the logic analyzer each time the user selects a new signal bank to measure. This saves considerable time and reduces errors over a manual process for making sure the MUX outputs are correctly reflected in the logic analyzer.
