A multi-resolution AHB on-chip bus tracer named SYS-HMRBT (AHB Multi-Resolution Bus Tracer) for versatile System-on-Chip (SoC) debugging and monitoring. The bus tracer is capable of capturing the bus trace with different resolutions, all with efficient built-in compression mechanisms, to meet a diverse range of needs. Experiments show that the bus tracer achieves very good compression ratios of 79% - 96%, depending on the selected resolution mode. The SoC has been successfully verified both in field-programmable gate array and a test chip.
