Microchip FPGA: How should I set the DQ Drive, DQS Drive, ADD/CMD Drive, and Clock Drive in the DDR Controller tab of the PolarFire SoC MSS Configurator?

Libero SoC PolarFire

The IBIS model generated by Libero SoC changes depending on the Drive setting.
Select the Drive value based on the SI simulation results using the IBIS model.

An example of the generated IBIS:


Unlike the use of DDR in Fabric, MSS DDR generates only one model according to the setting value. Please keep this in mind when performing SI simulation.
