what the best way to send data from FPGA to PC by JTAG communication?

Hi,

What is the best way to send data from FPGA to PC by JTAG Communication?

I ask about JTAG because I have no more free communication line left and I need information to be transmitted at a fast rate (above 3MHz).

Prefers a solution without use of NIOS.

Also, which tool in Quartus is recommended for reading data from JTAG?

Thank

Hi Amir,

 

You could use System Console or a JTAG bridge. These designs take advantage of Platform Designer and don't require Nios.

 

Link to JTAG Bridge. It's on pages 57 and 149.  https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ug/ug_embedded_ip.pdf 

 

System Console user guide:  https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ug/ug_system_console.pdf

Following the previous question, I will detail the intention -
I have a list of registers in the FPGA and I want to extract data from them at a fast rate (above 3MHz). This means that the data I have selected will be sent permanently until some stop conditions are reached.

I am currently able to pull the data from the "jtag to avalon master bridge" in the System Console by commanding "master_read_32 $claim_path".
