Problems solved by technology

[0003] At present, mainstream IC verification platforms are usually built based on system verilog. System verilog refers to the SV language, which is a hardware description and verification language. The system verilog platform only provides randomization methods for fixed-point (integer) data. No randomization method provided for floating point data

Abstract

The invention provides an integrated circuit chip verification method and device, electronic equipment and a storage medium, and relates to the field of artificial intelligence such as an artificial intelligence chip and cloud computing, and the method comprises the steps: obtaining a first parameter and a second parameter, the first parameter being a required floating-point number value upper limit, and the second parameter being a required floating-point number value lower limit; respectively generating a first sign bit, a first exponential bit and a first decimal bit of the randomized floating-point number according to the first parameter and the second parameter; and generating the floating-point number according to the first sign bit, the first index bit and the first decimal bit, and performing integrated circuit chip verification by using the floating-point number. By means of the scheme, randomization of the floating point data can be achieved, and therefore required floating point data excitation and the like are provided for verification of related arithmetic units in integrated circuit chip verification.

Description

technical field [0001] The present disclosure relates to the field of artificial intelligence technology, and in particular to an integrated circuit chip verification method, device, electronic equipment, and storage medium in the fields of artificial intelligence chips and cloud computing. Background technique [0002] The randomized data stimulus is very important for the verification of an integrated circuit chip (IC, Integrated Circuit), and the chip may be a voice chip or the like. [0003] At present, mainstream IC verification platforms are usually built based on system verilog. System verilog refers to the SV language, which is a hardware description and verification language. The system verilog platform only provides randomization methods for fixed-point (integer) data. No randomization method is provided for floating point data. Contents of the invention [0004] The disclosure provides an integrated circuit chip verification method, device, electronic equipment...
