Parameterization unit circuit establishing method and standard unit circuit replacing method and device

Abstract

The embodiment of the invention provides a parameterization unit circuit, a parameterization unit circuit establishing method and a standard unit circuit replacing method, and the parameterization unit circuit establishing method comprises the steps: in a circuit, determining at least one unit circuit capable of being standardized as a standard unit; establishing a parameterization unit which corresponds to the standard unit and is consistent with the standard unit in circuit function; configuring a mapping relation between the parameterization unit and the standard unit; according to the unit mapping information and the port mapping information, calling a standard unit schematic diagram in a parameterized unit to form a parameterized unit schematic diagram; verifying whether the circuit functions are consistent or not according to a circuit netlist generated by the parameterized unit schematic diagram and a parameterized unit function description language; if the verification is consistent, regarding that the verification is passed; otherwise, reconfiguring the mapping relation between the parameterized unit and the standard unit. According to the embodiment of the invention, the result of the first replacement can be repeatedly utilized, and different standard units can be conveniently and efficiently replaced.

Description

technical field [0001] The embodiment of the present application relates to the field of chip technology, and specifically relates to a parameterized unit circuit and a method for establishing it, and a method and device for replacing a standard unit circuit. Background technique [0002] Custom integrated circuits are integrated circuits specially designed and manufactured according to user needs. As the integration scale becomes larger and larger, the design becomes more and more complex. In order to complete the design in a short time, designers often use computer-aided design systems ( EDA) unit circuit library design method, using standard units to build logic circuits, and calling pre-designed circuits in integrated circuits. The pre-designed circuit may be a circuit designed by the designer before, or it may be purchased from other craft factories or sales companies. [0003] If it is necessary to modify the pre-designed circuit, manual wiring is required. Even if on...

Problems solved by technology

And if the port names in the units replaced before and after are inconsistent, the replacer needs to spend more time checking port information, etc.

When the process is migrated or the circuit needs a lot of modification, it will be a lot of work to make manual modifications
