LogiCORE CAM v6.1 - CAM does not support partial initialization of core


CAM v6.1 does not currently support partial initialization. If the CAM is initialized with a .COE initialization file and the number of entries contained within that .COE file is less than the total available CAM depth, the uninitialized locations will not behave as "empty" locations. Instead, the "empty" locations will get initialized to '0', and this might result in unexpected matches for a search entry for a data value of '0'.


To avoid this unexpected behavior, you should initialize the CAM with a .COE file that has a data value defined for every memory location contained within your core.
