Node Finder Signal Tap

Hi,

Then may be can try with the preserve or noprune attribute in the second link posted https://www.intel.com/content/www/us/en/docs/programmable/683819/23-4/preserve-for-debug-overview.html

Preserve link https://www.intel.com/content/www/us/en/programmable/quartushelp/17.0/hdl/vhdl/vhdl_file_dir_preserve.htm

Noprune link https://www.intel.com/content/www/us/en/programmable/quartushelp/17.0/hdl/vhdl/vhdl_file_dir_noprune.htm

I had tried with a sample code and I can find the signal in signal-tap check screenshot below:

Code:

entity example_module_vhdl is

port (

a, b : in std_logic

);

end entity example_module_vhdl;

architecture Behavioral of example_module_vhdl is

signal and_result : std_logic;

attribute noprune: boolean;

attribute noprune of and_result: signal is true;

begin

process(a, b)

begin

and_result <= a and b;

end process;

end architecture Behavioral;

Screenshot:

Thanks,

Regards,
