The BSDL files for HardCopy II devices are different from the
corresponding Stratix
BSDL files for IEEE Std. 1149.1- compliant Hardcopy II devices, visit the
Altera website at www.altera.com.
The HardCopy II device instruction register length is 10 bits and the
USERCODE register length is 32 bits. The USERCODE registers are not
reprogrammable and are mask-programmed. The designer can choose an
appropriate 32 bit sequence which will be programmed into the
USERCODE registers.
