The "R2CLDynFixDiag.rcl " file is for an camera simulator that we use here in production. It is proprietary and not for sale. In fact it would not be all that useful as it is designed to make sure the boards are manufactured correctly, and not much else.
The boards can produce a synthetic image, for the R2/R3 family, the camera configuration files are usually called "BFSynt256E1.*" If you used SysReg to attach these camera files to your board, it will provide simple ramp images.
Another option is to buy a camera simulator from Vivid Engineer:
They make a wide variety of camera simulators which are fully programmable.
