Hi, 

I am trying to read data from EPM712SQC100-7, using USB Blaster. 

Quartus-II isable to detect Device when i press "AUTO DETECT". JTAG chain is OK and intact.  

I am not able to read data as "EXAMINE" check box is disabled. 

Only "Blank check" box is active. 

 

Pls. help. 

 

Thanks a Lot

The 'examine' function is only available if the CPLD is not protected by a security bit.
