Pull Request Test Coverage Report for Build 12918090684Details
💛 - Coveralls |
Initialize the read/write start address to zero by default. Signed-off-by: Peter Colberg <peter.colberg@altera.com>
Add a function version_code() to combine major and minor version into a single code for comparison to, e.g., guard version-dependent features. Signed-off-by: Peter Colberg <peter.colberg@altera.com>
Add High Bandwidth Memory (HBM) support to the memory traffic generator (mem_tg) sample used to exercise and test available memory channels, which currently supports DDR memory only. For DDR, each memory channel accesses an independent memory bank, each starting from offset 0. For HBM, each memory channel has access to the entire memory space and must therefore access memory from different locations when reading or writing on multiple channels simultaneously to avoid collisions. For details on the HBM memory architecture, refer to the Intel Agilex® 7 M-Series FPGA Network-on-Chip (NoC) User Guide.
