Test excitation generator of complex algorithm and control method thereof

Abstract

The invention relates to a test excitation generator of a complex algorithm and a control method of the test excitation generator. The test excitation generator comprises a fixed vector generation module, a random vector generation module, a special vector generation module, a time sequence monitoring module, a verification scheme input interface module, a time sequence signal input interface module and a test excitation output interface module. The fixed vector generation module generates excitation such as register reset read-write attributes, and the random vector generation module generates constrained randomized excitation; the special vector generation module generates special excitation which cannot be generated by adopting a SystemVerilog randomization command; the test excitationgenerator obtains a control signal through the verification scheme input interface module, controls different vector generation modules to generate corresponding test excitation, and outputs the testexcitation through the test excitation output interface module; the test excitation generator acquires a control signal through the time sequence signal input interface module, and controls the loading and verification starting of the output test excitation; the time sequence monitoring module monitors state information of the complex algorithm verification system through the time sequence signalinput interface module. The method is suitable for test excitation generation of a complex algorithm realized by pure hardware or software and hardware collaboration, and the quality and efficiency ofcomplex algorithm verification can be effectively improved.

Description

technical field [0001] The invention belongs to the simulation verification of complex algorithm modules in the field of integrated circuit design, and in particular relates to a test excitation generator for complex algorithms and a control method thereof. Background technique [0002] Generally speaking, the complexity of an algorithm determines the complexity of its RTL implementation to a large extent. In order to ensure the functional coverage of the verification, the RTL simulation verification scheme of complex algorithms will inevitably become large and cumbersome. In particular, according to different application requirements, the same type of complex algorithm may adopt multiple implementation methods such as software and hardware coordination or pure hardware to obtain more flexible application characteristics or achieve higher data throughput. The high complexity and diverse implementation methods make the RTL simulation verification of complex algorithms more di...
