CLBs in Versal ACAP have been enhanced from previous architectures. CLB resources that are no longer supported in Versal ACAP (e.g., CARRY8, MUXF7, MUXF8, MUXF9, etc.) are automatically migrated by inferring the appropriate Versal ACAP block. RTL instantiations are also automatically migrated. For optimal area and timing results, Xilinx recommends that you do not instantiate CLB UNISIMs that are no longer supported in Versal ACAP and that you re-synthesize your RTL to infer the appropriate Versal ACAP block. For detailed architectural differences, see the Versal ACAP Configurable Logic Block Architecture Manual (AM005).
