摘要：AMBA (Advanced Microcontroller based Bus Architecture) consists of AHB, APB, ASB and AXI. In this project we are Tracing AHB (Advanced High performance Bus) signals with Real time Compression and Multi-resolution Techniques. A simple transaction on the AHB consists of an address phase and a subsequent data phase. Access to the target device is controlled through a MUX , thereby admitting bus-access to one bus-master at a time. In AHB Tracer we have to Trace Address signals, Data signals and Control signals, we have to compress them depending on AHB protocols. A multi-resolution AHB on-chip bus tracer is named as SYS_HMRBT (AHB Multi-resolution Bus Tracer) and is used for monitoring. The goal is to provide better compression quality and multiple resolution traces to meet the complex SoC debugging needs. Compressing all signals at cycle-accurate-level does not always meet the debugging needs. As SOCs become more complex, the transaction level debugging becomes increasingly important, since it helps designers focus on the functional behaviors, instead of interpreting complex signals. By using this SYS_HMRBT, we can achieve 79%-96% of compression depending on selected resolution mode. Tools Used for this Project are Modelsim for Simulation, and Xilinx ISE II for Synthesis.
