HBM2E (High Bandwidth Memory) is a high-performance 3D-stacked DRAM used in high-performance computing and graphic accelerators. It uses less power but posts higher bandwidth than graphics cards relying on DDR4 or GDDR5 memory. Validating the performance and utilization of memory is a big challenge for users due to complex structure of SoC and the subsystem attached to it such as memory subsystem, interconnect bus, and processor.

³§²â²Ô´Ç±è²õ²â²õ¡¯&²Ô²ú²õ±è;Verdi Performance Analyzer provides a solution. This blog will provide insight into how Verdi Performance Analyzer natively integrated with ²ÝÁñÉçÇø VIP can be used to measure key performance metrics like number of commands, count of page empty scenarios that occur in a test. All of these metrics can be used for performance benchmarking.

Memory Transaction Flow

The basic memory access flow can be described as opening a bank using an Activate command, followed by Writing or Reading from various addresses in the bank, and finally closing the bank using a precharge command.
