Providing ASIC equivalents of FPGAs is facilitated and made more efficient and economical by using an ASIC architecture including a plurality of so-called hybrid logic elements (“HLEs”), each of which can provide a portion of the full functionality of an FPGA logic element (“LE”). The functionality of each FPGA LE implementing a user's logic design can be mapped to one or more HLEs without re-synthesis of the user's logic. Only as many HLEs as are necessary are used to perform the functions of each LE. The one-for-one equivalence between each LE and either (1) one HLE or (2) a group of HLEs facilitates mapping (without re-synthesis) in either direction between FPGA and ASIC designs.

The invention discloses a positive feedback XOR / XNOR gate and a hybrid logic adder. The hybrid logic adder comprises a positive feedback XOR / XNOR gate and an output circuit. The positive feedback exclusive-OR / XNOR gate comprises a first PMOS tube and a second PMOS tube which are used as transmission tubes, and a first NMOS tube and a second NMOS tube which form a pull-down network. The third PMOStube, the third NMOS tube and the fourth NMOS tube form a positive feedback loop; when the exclusive-OR logic output end of the positive feedback exclusive-OR / exclusive-OR gate is pulled down to be below the switching threshold value of an inverter composed of a third PMOS tube and a fourth NMOS tube, the exclusive-OR logic output end of the positive feedback exclusive-OR / exclusive-OR gate is switched off. The positive feedback loop starts to work, so that the exclusive-OR logic output end of the positive feedback exclusive-OR / XNOR gate enters an accelerated pull-down period and is successfully pulled down to a low level, and threshold-voltage-loss-free is realized; the invention has the advantages of no threshold voltage loss, and small time delay and power consumption time delay product.

The invention discloses a control method for high-power reactive and harmonic dynamic hybrid compensation method. The hybrid compensation system comprises an SVG (static var generator), a TSF (thyristor switched filter) group and a controller, and the SVG and TSFs are parallelly connected to a grid. The three-phase current of the grid between the SVG and the TSFs is taken as a detection object, voltage and current values collected by sensors are processed through the controller, switching signals of the TSFs are acquired according to hybrid logic judgment, most of the reactive power of loads is compensated in a graded manner, and specific subharmonic is filtered out; control parameters of the SVG are acquired according to an instantaneous-power theory, and the surplus reactive power and harmonic of the loads are continuously compensated. A cost-effective scheme for rapid continuous compensation of the high-power reactive and harmonic is provided, impact of switching of passive equipment on the grid can be completely avoided, and harmonic current is avoided flowing to the grid, so that the control method is energy saving, emission reducing, green, environment friendly, good in social and economical effectiveness, wide in application range and especially applicable to the field of oil drilling.
