Description
The AXI crossbar will only be verified at top-level for the 1st stage of the project with a preliminary version of the SCB and usage of an open source AXI agent/VIP (potential sources: https://github.com/antmicro/axi-vip, which has been forked from https://github.com/SymbiFlow/axi-vip, also https://github.com/taichi-ishitani/tvip-axi/tree/master... -> need further seach).
- [x] First we need to find a reliable open source UVM AXI agent/VIP. This agent will be used at block-level later, but we can already start to use it at top level.
- [x] Then we need to add this AXI agent into our top DV env ([initial top env PR](https://github.com/lowRISC/mocha/pull/213)) for each AXI interface we want to monitor with binds.
- [x] Then create a simple scoreboard (reusable if possible at block level where we'll extend its features later).
- [x] Instantiate this SCB and connect the TLM ports to all the AXI monitors.
- [x] Make sure the SCB is able to check in/out AXI transactions against each other and check if the AXI transactions have been routed properly.
