Abstract: Reset circuitry for an integrated circuit is presented. An internal oscillator produces an oscillating signal upon power-up of the integrated circuit. The internal oscillator is not dependent on signals generated outside the integrated circuit. An electro-static discharge blocker circuit receives an external reset signal generated outside the integrated circuit. The electrostatic discharge blocker circuit utilizes the oscillating signal to perform electro-static discharge blocking for the external reset signal to produce an internal reset signal.

Abstract: A system and method for emulating an ASIC using multiple filed programmable gate arrays. A designer, using this method, emulates an integrated circuit design using a prototyping apparatus. The method includes reserving more than one location in a prototyping apparatus for a circuit block that is part of an ASIC design. Each of the reserved locations is coupled to a single interconnection point within the prototyping apparatus. By reserving more than one space for the possible locations of each circuit block, a designer can choose late in the design process where to finally place each circuit block, thereby allowing for design changes without problematic resynthesis and communication path reroutes.
