10M08SCE144I7G

We use 10M08SCE144I7G CPLD, and colleagues in the department wonder whether outsiders have the opportunity to read or copy the burned data from this IC through JTAG or other methods.

Hello,


If you have access to JTAG to this device, you can download the programming file which you already programmed into the device by enabling the "examine" option in the Quartus Programmer tool.


regards,

Farabi

Dear Farabi，

What I want to express is that we are worried that the programming data of CPLD will be read out using JTAG or other methods.

Is there a protection mechanism to prevent data from being copied out ?
