CoolRunner-II - How do you program the usercode?


Is it possible to program a customer usercode in a CoolRunner-II CPLD?


It is possible to apply a User code to the CoolRunner-II CPLD; it is done in iMPACT in the programming properties:

You first select the programming properties and add the 8 HEX digit code (1).

Once the device is programmed, you can right click on the device and select "Get Device Signature/Usercode" (2) and this will display the user code in the console window (3).
