AXI-SmartConnect is constructed as an IP integrator hierarchical IP. The topology of AXI-SmartConnect is dynamically generated during the Validate step in the IP integrator. This allows AXI-SmartConnect to adapt to the characteristics of the connected endpoint AXI master and slave IPs. After performing Validate, the topology of SmartConnect will be generated and you can open the IP to tune the settings, reduce pipelining, and inspect clock domains, for example.
SmartConnect is tuned by default to help designs achieve high clock frequency, at the expense of latency and area.
