An apparatus for generating a function activation signal to activate a function in an integrated circuit device comprises a power-on circuit receiving a power input and initializing and generating a test activation signal, a test circuit receiving the test activation signal and generating a test result signal, and a threshold decision circuit receiving the test result signal and generating the function activation signal. The test circuit models a function of the integrated circuit device and generates the test result signal when the power input has reached a sufficient voltage to perform the function of the integrated circuit device. The threshold decision circuit generates the function activation signal if the test result signal indicates the power input has reached a sufficient voltage to perform the function of the integrated circuit device.

A method of accessing the testing means in a Field Programmable Gate Array ('FPGA') comprised of a plurality of functional groups ('FGs') comprising: inputting a function netlist defining a user circuit; compiling said function netlist; and generating a logic Built-In Self Test (&#x201c;BIST&#x201d;) netlist; wherein said BIST netlist replaces all user registers with scan registers with a scan chain routed as the physical silicon scan chains.

A grass guard for forming a vegetationless border around a perimeter of an object, such as a lawn sprinkler head, is described. One particular embodiment consists of a two layer construction. The top layer is a plastic sheet simulating grass. The bottom layer is made of a heavy grit bonded into a uniform body with a polymer. The layers form a relatively thin, weather resistant, plastically compliant disk with a center hole for stretch, self-adjusting fit over a pre-installed sprinkler head. The device is also easily cut through with a knife to fit various head locations. The bottom layer has an outside vertical edge with a top rounded corner enclosing the top layer to prevent edge delamination or fraying. An adhesive is provided to bond the grass guard to the neck of the sprinkler head to eliminate gap formation around the head. A hammering board can be used to facilitate the installation. Optionally, pre-watering the vicinity of the sprinkler head until the ground is softened from moisture further simplifies the installation and enhances the quality. In general, the device can be used to guard against the growth of vegetation next to any physical objects with the proper tailoring of geometry and choice of associated manufacturing process.

Effective and environmentally benign liquid deicing and anti-icing compositions are provided by aqueous solutions of (a) alkali metal acetates, preferably KAc, (b) phosphate ion, e.g., H.sub.3 PO.sub.4 or K.sub.3 PO.sub.4, (c) soluble silicate,, e.g., K.sub.2 SiO.sub.3 or Na.sub.2 SiO.sub.3, (d) aromatic triazole, preferably tolyltriazole, (e) a dye which provides a visible hue, and (f) a compatible surfactant which lowers the surface tension to below about 50 dynes per sq. cm., prevents aggregation of components (a) to (f), and assures excellent dispersion across aircraft surfaces, preferablty octylphenoxypolyethoxy ethylphosphate. These compositions are environmentally safe and are useful in methods for deicing or preventative anti-icing of aircraft that meet AEA, ISO and SAE aviation standards. These compositions remain effective at low temperatures and are non-corrosive to metals used in aircraft construction.
