Abstract: A simulation system includes an application, a chip model and an off-chip model. The application is configured to generate a corresponding instruction set in accordance with an application situation of a simulation circuit, wherein the simulation circuit includes a chip. The chip model receives the instruction set as an input to simulate operation of at least one intellectual property core of the chip via high-level languages in accordance with the at least one intellectual property core of the chip and to generate a power consumption and an I/O logic signal of the chip. The off-chip model constructs one or more orders of RLCG circuit cascading models in accordance with all or part of the off-chip model abstracted by the S parameter. The application program and the RLCG circuit cascading model are integrated for simulating and analyzing power integrity and signal integrity of the simulation system.

Abstract: The invention discloses a lock device. The lock device is used for detachably mounting a cover on a base. A recess is formed on the cover. A first hole is formed on the bottom of the recess, and a first retainer is extended out of the bottom of the recess. The lock device includes a first sliding member, a first elastomer, and a second sliding member. A column which is capable of passing through the first hole is formed on the first sliding member. A second retainer which is used for the first retainer to lock is formed on the second sliding member. When the first sliding member slides toward the base along a first axle, the column pushes the second retainer to make the second sliding member slide toward a second axle, so as to make the second retainer separate from the first retainer.
