Does anyone know if there is a way to lock code to work only on a particular fpga? I know the device has a jtag identifier, which identifies the fpga family, but I don't know if part of that idcode reflects a unique serial number associated to only 1 fpga. I'm looking to write some code that checks if the id of that fpga is valid, otherwise the code won't run.
Thanks,

only doable with flash FPGA or external nonvolatile memory on PCB is required.
RAM based FPGA have no serial number.
the jtagid is vendor and part type identifier only

Encrypted bit stream. Key is put into battery backed up register in FPGA, and unless the encryption and decryption keys match, the FPGA doesn't configure.
See:
If this is related to preventing a competitor from selling boards with your functionality after capturing your bitstreams and then programming identical FPGAs I solved this problem by going to Fuse-based FPGAs from Actel.
