2.3. Simulating the Example Design in ModelSim*
- In a terminal, change directory to <workingdir>/pcie_g3x8_integrated_tb/ep_g3x8_avmm256_integrated_tb/sim/mentor.
- Start the ModelSim* simulator (invoke vsim).
- To run the simulation, type the following commands in a terminal window:
- do msim_setup.tcl
- ld_debug
The ld_debug command compiles all design files and elaborates the top-level design without any optimization.
- run -all
The simulation performs the following operations:
- Various configuration accesses after the link is initialized
- Setup of the DMA controller to read data from the BFM’s shared memory
- Setup of the DMA controller to write the same data back to the BFM’s shared memory
- Data comparison and report of any mismatch
