Abstract

The embodiment of the invention discloses a verification system and a verification method for cooperative work among integrated circuit modules. The verification system includes: a stimulus model, a function simulation model, an interconnection circuit model, a memory model, and a scoreboard, wherein the interconnection circuit model is used to realize the alignment of the master circuit module and the slave circuit module in the circuit under test according to the configuration information of the interconnection circuit. Interconnection function; the scoreboard is used to verify the cooperative work between the master circuit module and the slave circuit module according to the expected value of the operation, the actual value of the master operation and the actual value of the slave operation. The verification system using the above-mentioned integrated circuit modules to work together can complete the verification of the interconnection function of the circuit under test and the multi-module cooperative work ability with high quality without interconnection circuits, memories, and upper-level integrated connection lines. Test circuit problems can be found and resolved earlier.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of integrated circuits, and in particular to a verification system and verification method for cooperating among integrated circuit modules. Background technique [0002] In chip design, especially 5G and artificial intelligence chips, large-scale interconnection of core circuit modules is essential. [0003] In the early development of integrated circuits, more than 70% of the workload is in the verification stage. However, the relevant verification environment has the following problems: in the interconnection circuit design, when the memory design and circuit integration are not completed, it is impossible to establish a verification environment for the collaborative work of the circuit modules, and then it is impossible to verify the collaborative work function of the core circuit modules. Circuit modules cannot be distributed in high quality individually. Correspondingly, ver...
