Honored ContributorExtracting .jic from cyclone III
Hi, Does anybody know if it is possible at all to extract and copy/open/read/write a design from a .jic file already installed on a Cyclone III FPGA? If yes, what are the ways to prevent ...

Honored Contributor --- Quote Start --- Does that mean, that no DS28E01 datasheet study is needed? Just use DS28E01 as a "black box"? --- Quote End --- Definitely yes. You need to read the datasheet in order to learn that you need a 2.2k pullup resistor between onewire signal (DS28E01 pin 2) and 3.3V supply: but now I have told you :cool:, so you should not need the datasheet at all. In the HDL code you only need to set your secure code key and possibly change the clock frequency. --- Quote Start --- What about hdl code - is it published somewhere or needed to be requested at Altera under NDA? --- Quote End --- Request at Altera. IIRC they don't require a NDA. They simply ask you generic details about your target application.
