该文主要讨论高级综合系统RTL(registertransferlevel)级综合结果正确性验证策略的确定及验证系统设计中DFG(dataflowgraph)逆向获取算法的设计与实现.算法主要包括4个处理阶段:FSM(finitestatemachine)动态分析及控制输出获取;FSM当前状态下数据通道有效元件分析;数据通道结构到DFG操作结点转换;DFG结点间数据依赖关系分析、共享寄存器变量分离及有向边的形成.
This paper mainly discusses the confirmation of the correctness of RTL (registertransferlevel) level synthesis verification scheme and the design and implementation of DFG (dataflowgraph) reverse acquisition algorithm in the verification system design. The algorithm mainly includes four processing stages: dynamic analysis of FSM (finitestatemachine) and acquisition of control output; effective element analysis of data channel in FSM current state; conversion of data channel structure to DFG operation node; data dependency analysis of DFG nodes, shared register Variable separation and the formation of directed edges.
