Embodiment Construction

[0047] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0048] At present, the commonly used memory test method is to design a BIST (Built-in Self Test) circuit around the memory. BIST is a technology that implants relevant functional circuits in the circuit to provide self-test functions during design. This reduces the dependence of device testing on automatic test equipment.

[0049] BIST is usually divided into MBIST (Memory BIST, memory built-in self-test) and LBIST (Logic BIST, logic built-in self-test). Compared with ATPG (Automatic Test Pattern Generation, automatic test vector generation), BIST can generate extremely high fault coverage rate through limited vectors, and realize memory testing.

[0050] In VLSI design, the logic design of MBIST mainly relies on special EDA (Ele...

Abstract

The embodiment of the invention provides a controller generation method and device and a storage medium, a high-level comprehensive tool and an instruction script for at least one random access memory(RAM) are preset, and the method comprises the following steps: writing a high-level programming language code of a controller into the high-level comprehensive tool; Generating a register transfer hierarchy code of the controller based on the high-level programming language code through the high-level synthesis tool; Wherein the register transfers a port of the controller described by the hierarchical code; Wherein the port comprises an effective port; And setting an effective port of the controller according to the instruction script and the register transfer hierarchy code. Compared with the mode that the controller is designed by transferring hierarchical codes through the handwriting register, the implementation complexity of the related algorithm of the controller is greatly reduced, the design time is shortened, the productivity is improved, and the test cost is reduced. Meanwhile, the problems that a special tool is single in algorithm and a custom algorithm is high in difficulty are solved.

Description

technical field [0001] The invention relates to the technical field of integrated circuits, in particular to a method for generating a controller, a device for generating a controller and a storage medium. Background technique [0002] With the development of integrated circuits, the area of ​​embedded memory in the chip is getting larger and larger. Due to the limitation of the number of chip ports and the complex mechanism of the memory itself, the test of embedded memory is facing great challenges. [0003] At present, due to the gradual expansion of the size and capacity of the embedded memory, the test cost of the memory increases accordingly. Therefore, how to optimize the test process of the embedded memory and reduce the test cost of the memory has become an urgent technical problem to be solved. Contents of the invention [0004] In view of the above problems, embodiments of the present invention provide a method for generating a controller, an apparatus for gene...
