摘要： The independent claims of this patent signify a concise description of embodiments. A hardware emulation system is configured to define a variable delay associated with each of a multitude of design clocks used in the circuit design, compute a compression value in accordance with the multitude of variable delays, detect a change in one or more of the variable delays, and recompute the time compression value in response to the detected change. The hardware emulation system is further configured to recompute the time compression using programmable circuitry disposed in the hardware emulation system and without stopping the hardware emulation system. Such circuitry may be disposed in a single programmable device disposed in the hardware emulation system or a multitude of programmable devices disposed in the hardware emulation system. This Abstract is not intended to limit the scope of the claims.

摘要： A radiator is formed by forming a multitude of slot antennas adjacent one another such that the spacing between each pair of adjacent slot antennas is smaller than the wavelength of the signal being transmitted or received by the radiator. The radiator achieves high efficiency by reducing the excitation of substrate modes, and further achieves high output power radiation by combining power of multiple CMOS power amplifiers integrated in the radiator structure. Impedance matching to low-voltage CMOS power amplifiers is achieved through lowering the impedance at the radiator ports. Each output power stage may be implemented as a combination of several smaller output power stages operating in parallel, thereby allowing the combination to utilize an effective output device size commensurate with the impedance of the radiator.
