使用VIP models实现基于AXI协议的功能测试平台 HIT NoC Research Group Siyue Sun 2007.04.15 Task Progress on This Week (No.) HIGHLITES: 无 TASKS: 实现基于AXI协议的测试平台 STATUS: 掌握VIP的使用，结合VMM实现测试平台 PLANS: 细节问题的研究以及应用于我们的测试平台上 Agenda Introduction to VIP Integration with VMM 概述 基本概念 Base Classes Other components 测试平台的运作流程 初步建立的框架 Introduction to VIP Introduction to VIP Integration with VMM---概述 RVM：The Reference Verification Methodology VMM： The SystemVerilog Verification Methodology Integration with VMM---概述 Integration with VMM---概述 Integration with VMM --- 基本概念 Ports AxiMonitorInterface.svi AxiMasterInterface.svi AxiSlaveInterface.svi Integration with VMM ---基本概念 Factory Provided to a generator as the template for the generated objects. A blueprint for randomization Integration with VMM ---基本概念 Constraints The constraints define the range of randomized values that are used to create each object during the simulation Integration with VMM -- Base Classes Integration with VMM --- Other components Generator: Create constrained random objects, typically transactions. 方法一：扩展vmm_xactor 方法二：VMM provides two macros (vmm_atomic_gen and vmm_scenario_gen) that you can use to define a generator class. Integration with VMM --- Other components Callbacks For each transactor, DesignWare VIP includes a class that contains a set of callback methods. callbacks are an access mechanism can be used for several applications. ● Access for functional coverage ● Access for scoreboarding ● Insertion of user-defined code Channel Pre/Post Actions post_input_channel_get pre_output_channel_put pre_activity_channel_put Callbacks: Callbacks: Callbacks: 测试平台的运作流程---a simple example 测试平台的运作流程---总结 Generate a transaction: ues factory and generator A transaction request: Master transactor gets dw_vip_axi_master_transaction from input channel Master
