Research on ‘Building Block’ Digital Logic Simulation Platform in SaaS Mode *

In response to the problems of cumbersome installation and configuration, poor compatibility, rigid simulation devices, and lack of creativity in traditional digital logic virtual simulation platforms, this paper proposes the concept of building a “building block” style digital logic system based on the SaaS (Software as a Service) model. The paper analyzes in detail the challenges of drawing and simulating digital logic circuits in a “building block” style, studies the visual recognition method of logic devices based on SVG (Scalable Vector Graphics) technology, and introduces recursive and iterative algorithms for tree-based logic simulation. The design and implementation of the simulation platform based on SaaS technology are also presented.
