Writing into registers in simulation

[AnotherKamila]

Hello,

My project relies on the control plane writing the right data into registers. Therefore, in order to be able to test the functionality in the simulation, I would need to be able to write into registers as part of the simulation (i.e. when I run vivado_sim.bash). Can you please give me some pointers for how to do that?

If I can figure out how to do that, I could make that functionality available from the commands.txt file, so that it is easy to use for everyone.

There is currently no good way of configuring P4 registers before running the SDNet vivado_sim.bash script. However, you can configure registers when running the full SUME simulation. See the switch_calc project for an example: https://github.com/NetFPGA/P4-NetFPGA-live/blob/master/contrib-projects/sume-sdnet-switch/projects/switch_calc/simple_sume_switch/test/sim_switch_ctrlWrites/run.py#L131
