Abstract: A signal integrity simulation method for an encryption hybrid model is provided. A step response data of a SPICE model is extracted through a transient simulation. An external random code signal is generated. The extracted step response data is imported as an input source for an ADS channel simulator. An eye diagram at a RX end is calculated by the ADS channel simulator based on an algorithm and the external random code signal, to perform measurement on the eye diagram. With the signal integrity simulation method for an encryption hybrid model such as an IBIS AMI model, the problem that signal integration simulation cannot be accurately performed or cannot be performed because models provided by the manufacturer are encrypted or the types of models provided by the manufacturer are not consistent can be effectively solved.

Abstract: The present invention provides a method for the preparation of an insensitive high enthalpy explosive Dihydroxylammonium 5,5?-bistetrazole-1,1?-diolate (TKX-50) in the presence of N,N-dimethylformamide, N,N-dimethylacetamide, or N-Methyl-2-pyrrolidone as a solvent via a four-step, one-pot reaction route to obtain a final product after four reaction steps. The more dangerous intermediate diazidoglyoxime may be solved by the one-pot method without the need of isolation. Further, the cyclization reaction is carried out in the presence of dropwisely added concentrated sulfuric acid to replace hydrochloric gas so no hydrochloric gas generator is needed to greatly reduce the amount of waste acid so as to effectively reduce the cost by avoiding using hydrochloric gas steel cylinders which require much safety equipment.
