Simulation Debug - 5.0 English - PG118

The simulation debug flow for Mentor Graphics Questa Advanced Simulator is described below. A similar approach can be used with other simulators.

• Check for the latest supported versions of Questa Advanced Simulator in the Vivado Design Suite User Guide: Release Notes, Installation, and Licensing (UG973). Is this version being used? If not, update to this version.
• If using Verilog, do you have a mixed mode simulation license? If not, obtain a mixed-mode license.
• Ensure that the proper libraries are compiled and mapped. In the AMD Vivado™ Design Suite this is done within the tool using Flow > Simulation Settings.
• Have you associated the intended software program for all connected MicroBlaze™ processors with the simulation? Use Tools > Associate ELF Files in the AMD Vivado™ Design Suite to do this.
• When observing the traffic on any of the AXI4 interfaces connected to the System Cache core, see the AMBA® AXI and ACE Protocol Specification for the AXI4 timing.
• To speed up simulation C_ENABLE_FAST_INIT_SIM can be enabled to to reduced the initialization sequence duration after reset. This feature is for simulation only, the full initialization sequence is always performed in hardware.
