CPM5 QDMA1 Gen4x8 Functional simulation example design:

  • This design has CPM5 – QDMA1 enabled in Gen4x8 configuration as an End Point
  • The design support simulation
  • Enables QDMA AXI4 and QDMA AXI-ST functionality with 4 PF and 252 VFs
  • The design includes Root Port testbench, which simulates QDMA AXI4 and AXI4-Stream datapath.

Example design registers are listed under CPM5_QDMA_Gen4x8_MM_ST_Design section.

Note: Before doing data transfers, you must clear the context for that queue. First, you must clear the perfetch context and the software context for the hardware context and credit context for simulation to work properly.
